We combined acoustic pharyngometry (APh) and speech data from 42 adults to benchmark eight widely used formant-based VTL estimators against incisors-to-glottis length and to test an interpretable two-stage bias-corrected linear estimator. Across more than 400 000 central frames with valid F1–F4, traditional quarter-wave, odd-harmonic, and dispersion-type estimators correlated with VTLAPh but showed poor out-of-sample anatomical recovery and strong calibration compression. Re-estimated one-stage linear models reduced mean absolute error (MAE; median �1.0 cm) but still overestimated shorter tracts and underestimated longer tracts. A two-stage model markedly improved calibration and agreement, outperforming one-stage linear and nonlinear alternatives (median per-vowel MAE 0.39 cm, median out-of-sample R2 ¼ 0:83). Front and front-rounded vowels were the most informative. Speaker-level 95\\% limits of agreement were about 60.9 cm, indicating that the method is better suited to aggregated tract-scale estimation than to direct anatomical measurement. These results identify calibration bias as a central limitation of standard formant-based VTL estimators and provide a practical, interpretable route to tract-scale estimation from similarly processed labeled-vowel data under matched conditions.},\n\tlanguage = {en},\n\tnumber = {6},\n\turldate = {2026-07-06},\n\tjournal = {The Journal of the Acoustical Society of America},\n\tauthor = {Friedrichs, Daniel and Guerrini, Urs and Ekström, Axel and Dellwo, Volker and Moran, Steven},\n\tmonth = jun,\n\tyear = {2026},\n\tpages = {5650--5666},\n}\n\n\n\n

Most research on voice learning is conducted in laboratory settings, where participants are\n              explicitly\n              instructed to attend to and memorize voices for later recognition. Yet, the impact of task awareness (awareness regarding the goal of voice learning) on voice recognition performance remains poorly understood. To address this gap, we conducted a study comparing two voice-learning modalities: explicit learning, instructing participants to listen to and memorize voices for later recognition, and implicit learning, based on exposure during a voice discrimination task, without awareness of a subsequent recognition test. After both exposure phases, participants completed a surreptitious old–new voice recognition task. To further examine whether task awareness is modulated by voice load (number of voice identities introduced in the experiment), we implemented both a simple and a challenging version of the experiment. We found that, irrespective of voice load, implicit learning through participation in a discrimination task, resulted in higher recognition performance than explicit listen-and-memorize training. These findings suggest that highly demanding explicit listen-and-memorize tasks may benefit from incorporating ecologically valid familiarization paradigms, such as voice discrimination. We discuss the implications of our findings in relation to previous empirical research and their relevance for forensic applications.},\n\tlanguage = {en},\n\tnumber = {1},\n\turldate = {2026-07-10},\n\tjournal = {Scientific Reports},\n\tauthor = {Fröhlich, Andrea and Ramon, Meike and French, Peter and Dellwo, Volker},\n\tmonth = mar,\n\tyear = {2026},\n\tpages = {13498},\n}\n\n\n\n

\n Introduction Cooperation is essential to humans and manifests in speech through acoustic convergence, in which interlocutors’ voices become more similar. Yet convergence can be limited when signaling individuality is more important than aligning with others. In such contexts, speakers may adopt non-accommodative strategies to preserve their vocal identity and recognizability. Drawing on animal communication research—which shows that species in larger social groups exhibit greater vocal individuality—we test how group size (3 and 5 interactants) shapes the balance between remaining identifiable while still cooperating to support communication. Methods In an interactive online game, players collaborated on a shared task while trying to recognize one another by voice, with the player recognized best receiving a reward. To assess how group size influences accommodation under these dual demands, we analyzed the speech of three players who participated in both game sessions. Acoustic features relevant to voice identity and amenable to accommodation—harmonicity, jitter, F0, formant dispersion, and duration—were extracted and reduced through Principal Component Analysis to two dimensions accounting for 52.9% of the variance. Following the identification of group size effects on these components, we assessed whether inter-speaker acoustic differences increased, decreased, or remained stable across conditions. Additionally, within-speaker variability was examined as a function of group size to determine whether observed changes in the five-player condition were driven by all speakers or only a subset. Results In larger groups, accommodation was selective: players modulated their acoustic features, maintaining some while converging on others. No significant differences as a function of group size were observed for PC1, interpreted as reflecting maintenance and primarily associated with voice quality measures (harmonicity and jitter). In contrast, significant differences emerged for PC2, largely driven by F0 standard deviation and duration. These changes indicated reduced inter-speaker differences in the larger group, consistent with convergence. In the larger group setting, convergence was observed when two speakers showed mutual alignment and also shifted toward the speech patterns of a third participant, who remained comparatively stable in their acoustic behavior. Discussion The pattern of selective and asymmetrical convergence indicates that speakers strategically balance the goals of cooperation and individuality, suggesting that recognizability demands also shape accommodation.\n

This study investigated whether the acoustic basis of voice discrimination remains stable across the linguistic levels of words and sentences. Mandarin-speaking listeners judged speaker identity (same/different) for word and sentence pairs with controlled similarity in a classic voice space. Interpretable machine learning classifiers were trained on acoustic differences between speech pairs to predict listeners’ judgments. Models performed well within levels, but generalization across levels declined and was asymmetric: sentence-trained models tended to overproduce different-speaker responses when tested on word data, whereas word-trained models showed a bias toward same-speaker responses when tested on sentence data. Feature importance rankings converged on a shared acoustic scaffold (spectral balance, formant structure, higher harmonics, and pitch) but highlighted the dominant role of temporal–prosodic cues (speech rate) and the growing relevance of variability-based cues for sentences compared with words. These findings refine prototype-based models of voice perception by demonstrating adaptive cue weighting across linguistic structure and offer implications for voice perception in naturalistic contexts. Methodologically, this study addressed an issue in the literature concerning the computation of variability measures for harmonic spectral features.},\n\tlanguage = {en},\n\turldate = {2026-08-03},\n\tbooktitle = {Speech {Prosody} 2026},\n\tpublisher = {ISCA},\n\tauthor = {Xu, Tianze and Jiang, Xiaoming and Dellwo, Volker},\n\tmonth = may,\n\tyear = {2026},\n\tpages = {609--613},\n}\n\n\n\n

This study examined between- and within-speaker variability in Persian voiceless fricatives (/f/, /s/, /S/, /x/) and how linguistic environments, such as syllable position and lexical stress, affect this variability. A gender-balanced sample of 24 Persian speakers was recorded in two sessions, 1–2 two weeks apart. Acoustic analysis targeted the ﬁrst four spectral moments and duration. Results showed that center of gravity captured the greatest between-speaker variability, followed by standard deviation, skewness, duration, and kurtosis. Across segments, the alveolar /s/ exhibited the highest speaker-speciﬁcity, followed by /S/, /f/, and /x/. Gender-based patterns emerged: for males, the center of gravity and skewness of /s/ were most discriminative, whereas for females, the center of gravity and standard deviation of /S/ were most effective. The labiodental /f/ showed some speaker-speciﬁc characteristics only in the male group. Voiceless fricatives in syllable-initial positions demonstrated more speaker-speciﬁcity, while lexical stress did not impact between-speaker variability. Results also highlight cross-linguistic differences in the acoustic cues most effective for speaker differentiation and demonstrate that optimal features can vary across speaker populations. Adaptive algorithms are therefore crucial for improving forensic speaker comparison.},\n\tlanguage = {en},\n\tnumber = {6},\n\turldate = {2025-12-21},\n\tjournal = {The Journal of the Acoustical Society of America},\n\tauthor = {Asadi, Homa and Alinezhad, Batool and Dellwo, Volker},\n\tmonth = dec,\n\tyear = {2025},\n\tpages = {4294--4307},\n}\n\n\n\n

Speciﬁcally, phonological and semantic relationships between spoken words have been observed to inﬂuence a listeners’ ability to discriminate voices. This study aims to develop our understanding of how different kinds of linguistic relationships, namely, phonetic relationships, inﬂuence the processing of speaker information. We conducted two experiments, a voice discrimination task and a voice similarity rating task, in which listeners were presented with pairs of speakers producing two words with various degrees of phonetic overlap. On the whole, higher quantities of phonetic overlap corresponded to higher speaker discrimination performance and higher similarity scores; however, the type of the phonetic overlap also mattered. Overlapping vowel segments showed substantial utility, while overlap of the phonological rhyme alone substantially lower performance. Results from this condition suggest that a phonological relationship within the word pair can interfere with otherwise increased quantities of phonetic overlap. These ﬁndings highlight the salience of the phonological rhyme in voice processing, as well as the overall impact of phonetic overlap.

Here, we test the neurocognitive sensitivity of 25 participants to accept or reject person identities as recreated in audio deepfakes. We generate high-quality voice identity clones from natural speakers by using advanced deepfake technologies. During an identity matching task, participants show intermediate performance with deepfake voices, indicating levels of deception and resistance to deepfake identity spoofing. On the brain level, univariate and multivariate analyses consistently reveal a central cortico-striatal network that decoded the vocal acoustic pattern and deepfake-level (auditory cortex), as well as natural speaker identities (nucleus accumbens), which are valued for their social relevance. This network is embedded in a broader neural identity and object recognition network. Humans can thus be partly tricked by deepfakes, but the neurocognitive mechanisms identified during deepfake processing open windows for strengthening human resilience to fake information.},\n\tlanguage = {en},\n\tnumber = {1},\n\turldate = {2024-10-07},\n\tjournal = {Communications Biology},\n\tauthor = {Roswandowitz, Claudia and Kathiresan, Thayabaran and Pellegrino, Elisa and Dellwo, Volker and Frühholz, Sascha},\n\tmonth = jun,\n\tyear = {2024},\n\tpages = {711},\n}\n\n\n\n

Part of the success has been attributed in prior work to their capability to model supra-segmental temporal information (SST), i.e., learn rhythmic-prosodic characteristics of speech in addition to spectral features. In this paper, we (i) present and apply a novel test to quantify to what extent the performance of state-of-the-art neural networks for speaker recognition can be explained by modeling SST; and (ii) present several means to force respective nets to focus more on SST and evaluate their merits. We find that a variety of CNN- and RNN-based neural network architectures for speaker recognition do not model SST to any sufficient degree, even when forced. The results provide a highly relevant basis for impactful future research into better exploitation of the full speech signal and give insights into the inner workings of such networks, enhancing explainability of deep learning for speech technologies.},\n\tlanguage = {en},\n\turldate = {2024-11-18},\n\tjournal = {Pattern Recognition Letters},\n\tauthor = {Neururer, Daniel and Dellwo, Volker and Stadelmann, Thilo},\n\tmonth = may,\n\tyear = {2024},\n\tpages = {64--69},\n}\n\n\n\n

Excessive vocal convergence may, however, weaken individual recognizability. This study aimed to explore whether constraints to convergence can arise in circumstances where interlocutors need to enhance their vocal individuality. Therefore, we tested the effects of group size (3 and 5 interactants) on vocal convergence and individualization in a social communication scenario in which individual recognition by voice is at stake.\n            \n            \n              Methods\n              In an interactive game, players had to recognize each other through their voices while solving a cooperative task online.

Here, we investigated the extent to which audio in video conferencing, subject to various lossy compression mechanisms, affects human voice recognition performance. Voice recognition performance was tested in an old–new recognition task under three audio conditions (telephone, Zoom, studio) across all matched (familiarization and test with same audio condition) and mismatched combinations (familiarization and test with different audio conditions). Participants were familiarized with female voices presented in either studio-quality (N = 22), Zoom-quality (N = 21), or telephone-quality (N = 20) stimuli. Subsequently, all listeners performed an identical voice recognition test containing a balanced stimulus set from all three conditions. Results revealed that voice recognition performance (dʹ) in Zoom audio was not significantly different to studio audio but both in Zoom and studio audio listeners performed significantly better compared to telephone audio. This suggests that signal processing of the speech codec used by Zoom provides equally relevant information in terms of voice recognition compared to studio audio. Interestingly, listeners familiarized with voices via Zoom audio showed a trend towards a better recognition performance in the test (p = 0.056) compared to listeners familiarized with studio audio. We discuss future directions according to which a possible advantage of Zoom audio for voice recognition might be related to some of the speech coding mechanisms used by Zoom.},\n\tlanguage = {en},\n\tnumber = {1},\n\turldate = {2024-11-18},\n\tjournal = {Scientific Reports},\n\tauthor = {Perepelytsia, Valeriia and Dellwo, Volker},\n\tmonth = oct,\n\tyear = {2023},\n\tpages = {18742},\n}\n\n\n\n

Even within a single utterance, speakers modify f0 to create different intonational patterns. Previous studies have identified markers of increased f0 variability, such as the introduction of a new topic or greetings, but these are limited in the scope of their analyses. In the present study, we investigate f0 variability over the course of a telephone conversation, with a focus on the initial and medial utterances within the exchange. We examined f0 standard deviation of each utterance in over 2000 telephone conversations from 509 American English speakers from the Switchboard corpus. Findings showed that on average, speakers exhibit more f0 variability in the opening compared to mid-conversation utterances. Further, findings suggest that the inclusion of a greeting word in an initial turn, e.g., “hello” or “hi”, corresponds to an increase in f0 standard deviation. These results suggest that speakers employed more variable f0 in the initial few turns of a telephone conversation. The interpretation of this finding is multifaceted and may be linked to several communicative goals, including the placement of identity markers in conversation or the attraction of attention, or the role of openings as boundary markers.},\n\tlanguage = {en},\n\turldate = {2025-04-18},\n\tbooktitle = {Interspeech 2022},\n\tpublisher = {ISCA},\n\tauthor = {Bradshaw, Leah and Chodroff, Eleanor and Jäger, Lena and Dellwo, Volker},\n\tmonth = sep,\n\tyear = {2022},\n\tpages = {101--105},\n}\n\n\n\n

Using the network analysis, the relationships between acoustic and kinematic variables were revealed. In particular, between-speaker articulatory behaviors were most dissimilar in /ɑ/ which requires less inherent spectral change. Moreover, when networks of speakers with similar formant patterns were compared, it was revealed that their articulatory behaviors also shared similarities, although they seemed to be organized in characteristic ways.

Some of the fundamental questions that this special collection aimed to cover concerned (1) the nature of vocal accommodation in terms of underlying mechanisms and social functions in human–human and human–computer interaction; (2) the effect of task-specific and talker-specific characteristics (gender, age, personality, linguistic and cultural background, role in interaction) on degree and direction of convergence towards human and computer interlocutors; (3) integration of articulatory, perceptual, neurocognitive, and/or multimodal data to the analysis of acoustic accommodation in interactive and non-interactive speech tasks; and (4) the contribution of short/long-term accommodation in human–human and human–computer interactions to the diffusion of linguistic innovation and ultimately language variation and change.},\n\tjournal = {Journal of Phonetics},\n\tpublisher = {Elsevier Ltd},\n\tauthor = {Pardo, Jennifer S. and Pellegrino, Elisa and Dellwo, Volker and Möbius, Bernd},\n\tyear = {2022},\n\tpages = {101196},\n}\n\n\n\n

Two experiments were conducted to investigate the role of amplitude envelope (ENV), segment duration (DUR), and speech rate (SR) on Italian listeners' ability to identify native-accented Italian in utterances produced by Zurich German speakers. In experiment 1, listeners judged in a two-alternative forced-choice perception task which of the two stimuli in a trial they perceived as more native-like. Stimuli in each trial only varied in ENV and DUR, which were retrieved either from a native Italian speaker [first language (L1) donor] or from a German speaker of Italian [second language (L2) donor]. Results revealed that listeners make use of both DUR and ENV to identify the more native-like stimuli, but the effect of ENV was more subtle. In experiment 2, SR differences (resulting from native and non-native segment duration differences in experiment 1) were normalized for. It was found that this drastically reduced the effect of segment durations in terms of perceived nativeness; however, the ENV effect still remained. This was not the case in a control group of listeners without competence in Italian. Though effects were subtle, the study shows that ENV cues contribute to the percept of nativeness in L2 speech.(c) 2021 Acoustical Society of America PU  - ACOUSTICAL SOC AMER AMER INST PHYSICS PI  - MELVILLE PA  - STE 1 NO 1, 2 HUNTINGTON QUADRANGLE, MELVILLE, NY 11747-4502 USA},\n\tnumber = {4},\n\tjournal = {The Journal of the Acoustical Society of America},\n\tpublisher = {Acoustical Society of America},\n\tauthor = {Pellegrino, Elisa and Schwab, Sandra and Dellwo, Volker},\n\tyear = {2021},\n\tpages = {2836--2853},\n}\n\n\n\n

However, there was no significant difference between explicit and non-explicit training nor was there an effect on stress processing under different phonetic variability conditions.

In a correctness judgment task involving correctly and incorrectly stressed penults and antepenults, we found that incorrectly stressed penults do not evoke an N400 effect, whereas incorrectly stressed antepenults do: there is increased negativity with a peak latency around 350–600 ms from word onset. Only changes to words with exceptional stress cause lexical inhibition, hence exceptional but not default stress markers are stored in the lexicon. Additionally, differences in processing patterns between the N400 and the late positivity component window point to an integration of two stages of word processing: pre-lexical stress recognition and stress-to-meaning matching. The results of the study support the view that stress should be understood as abstract phonological information.},\n\tlanguage = {en},\n\turldate = {2025-04-18},\n\tjournal = {Journal of Neurolinguistics},\n\tauthor = {Broś, Karolina and Meyer, Martin and Kliesch, Maria and Dellwo, Volker},\n\tmonth = feb,\n\tyear = {2021},\n\tpages = {100959},\n}\n\n\n\n

In behavioral experiments, we found that French listeners were able to improve their ability to discriminate stress contrasts in Spanish after a 4-h training. This indicates that French listeners' stress detection disadvantage can be reduced by a short exposure to L2 stress contrasts. An ERP experiment administered after the training evidenced that the larger the P3b amplitude, the better the listeners' training outcome. In contrast, listeners' performance was not reﬂected by the N2b amplitude. In other words, listeners with high performance after training showed similar auditory sensitivity to stress in comparison to listeners with poor performance, but they better maintained stress information in working memory, as indicated by the larger amplitude of P3b. The present research indicates that individual diﬀerences in working memory processing should be considered in the acquisition of second language prosody.},\n\tlanguage = {en},\n\turldate = {2025-04-18},\n\tjournal = {Journal of Neurolinguistics},\n\tauthor = {Schwab, Sandra and Giroud, Nathalie and Meyer, Martin and Dellwo, Volker},\n\tmonth = aug,\n\tyear = {2020},\n\tpages = {100897},\n}\n\n\n\n

After game 1, the players received the result of the game on a success scale from 1 (lowest success) to 5 (highest). Speakers’ fo accommodation was measured as the Euclidean distance between the human speakers and each human and the robot. Results revealed that (a) the duration of the game had no influence on the degree of fo accommodation and (b) the result of Game 1 correlated with the degree of fo accommodation in Game 2 (higher success equals lower Euclidean distance). We argue that game success is most likely considered as a sign of the success of players’ cooperation during the discussion, which leads to a higher accommodation behavior in speech.},\n\tlanguage = {en},\n\turldate = {2025-04-18},\n\tbooktitle = {Interspeech 2019},\n\tpublisher = {ISCA},\n\tauthor = {Ibrahim, Omnia and Skantze, Gabriel and Stoll, Sabine and Dellwo, Volker},\n\tmonth = sep,\n\tyear = {2019},\n\tpages = {3980--3984},\n}\n\n\n\n

In this paper, we propose a new dynamic feature called cepstral deltas/derivatives to improve emotion recognition performance. We have used two emotion speech datasets of different languages (German, and English) to study the performance of cepstral deltas. The MFCCs are used as a base feature to compare the performance of the proposed feature and traditionally used temporal deltas. The result shows that the addition of cepstral deltas with MFCCs improves the performance of specific emotions in different languages. The possible performance of cepstral deltas in other classifiers like support vector machine and deep neural networks is discussed.},\n\tbooktitle = {2019 {IEEE} 4th {International} {Conference} on {Signal} and {Image} {Processing}, {ICSIP} 2019},\n\tauthor = {Kathiresan, T. and Dellwo, V.},\n\tyear = {2019},\n}\n\n\n\n

For the French listeners, results showed that the better the music aptitude the better the stress discrimination performance (before and after training). Regarding German listeners, music aptitude did not show any effect on the discrimination of stress contrasts in Spanish L2. The link between music and L2 stress discrimination in French listeners (and its absence in German listeners) suggests that French and German listeners do not process stress information in the same way. It might be that, since French listeners, contrary to German listeners, are not used to stress encoding mechanism in their native language, they interpret information related to L2 prosody (such as lexical stress) in a more "musical way".},\n\tbooktitle = {International {Congress} of {Phonetic} {Sciences} ({ICPhS})},\n\tauthor = {Schwab, Sandra and Dellwo, Volker},\n\tyear = {2019},\n\tpages = {1927--1931},\n}\n\n\n\n

The present study investigated mid and low nasal vowels of Pwo speakers from Mae Hong Son province, Thailand. Due to the higher tendency of language contact with Thai, the younger group’s nasal vowels were expected to lose more nasality than the older group. The emergence of final nasal consonants was also expected in the younger group. The nasalization duration and consonant duration of both groups were analyzed. The results showed that, regardless of age, mid nasal vowels of some speakers had final nasal consonants, while low nasal vowels of all speakers did not. Furthermore, the older group had both longer nasalization duration and consonant duration than the younger group, suggesting their higher tendency to preserve nasality. The younger group had shorter nasalization duration and consonant duration, indicating the loss of nasality in vowels without compensatory final nasal consonants. The change might be due to the vowel quality. High vowels were fully denasalized with no compensatory final nasal consonants. Mid vowels were nasalized with the emergence of final nasal consonants. Low vowels remained nasalized without final nasal consonants. We could not confirm that the emergence of final nasal consonants was induced by Thai because it occurred in both groups.

Results revealed better performance for the steady-state compared to the changing conditions and within the steady-state condition, performance was poorest for high fo. In experiment II, we tested 9 human listeners on a subset of 4 speakers from experiment I. They went through two training tasks (training 1: multi-word utterances; training 2: words). In the test, they recognized speakers based on the same vocalic utterances as in experiment I (for these 4 speakers). Results showed that performance was about equally high for the changing and steady-state vowels, however, in the steady-state condition performance was best for high fo vowels. The experiments suggest that (a) fo has an influence on the strength of speaker specific characteristics in vowels and (b) humans - compared to machines - pay attention to different acoustic information in vocalic utterances for speaker recognition.},\n\tnumber = {September},\n\tbooktitle = {Proceedings of the {Annual} {Conference} of the {International} {Speech} {Communication} {Association}, {INTERSPEECH}},\n\tpublisher = {ISCA},\n\tauthor = {Dellwo, Volker and Kathiresan, Thayabaran and Pellegrino, Elisa and He, Lei and Schwab, Sandra and Maurer, Dieter},\n\tmonth = sep,\n\tyear = {2018},\n\tpages = {3795--3799},\n}\n\n\n\n

In order to contribute to the building up of such references, a novel database of vowel sounds that exceeds any existing collection by size and diversity of vocalic characteristicsis presented here, comprised of c. 34600 utterances of 70 speakers (46 nonprofessional speakers, children, women and men, and 24 professional actors/actresses and singers of straight theatre, contemporary singing, and European classical singing). The database focuses on sounds of the long Standard German vowels /i?y?e?ø???a?o?u/ produced with varying basic production parameters such as phonation type, vocal effort, fundamental frequency, vowel context and speaking or singing style.

The evidence obtained so far is based on speakers of stressed-timed languages, which are assumed to have complex consonant clusters and a higher degree of vowel reduction. Speakers of stressed-timed languages might operate their articulatory organs in different ways due to the syllable complexity and vowel reduction. Complex consonant clusters are released differently, and vowel reduction tends to be produced more or less strongly depending on speakers. When a language lacks such features, it is possible that rhythmic variation between its speakers decreases. In the present study, we aimed at exploring between- and within-speaker rhythmic variability in Persian, an Indo-European language categorised as syllable-timed. Acoustic correlates of speech rhythm (\\%V, \\{{\\textbackslash}ensuremath\\{{\\textbackslash}Delta\\}\\}V[ln], \\{{\\textbackslash}ensuremath\\{{\\textbackslash}Delta\\}\\}C[ln], n-PVI-V) and articulation rate were obtained from two Persian corpora with different sources of within-speaker variability. In the first corpus, the source of within-speaker variability mainly comes from non-contemporaneous recording sessions, and in the second corpus, from different speech rates. Results revealed that there were significant differences between speakers in all investigated speech rhythm measures in Persian and \\%V best discriminated between speakers. This reveals that the lack of typical stress-time features does not affect between-speaker variability in speech rhythm.},\n\tnumber = {2},\n\tjournal = {International Journal of Speech Language and the Law},\n\tpublisher = {Equinox Publishing Ltd.},\n\tauthor = {Asadi, Homa and Nourbakhsh, Mandana and He, Lei and Pellegrino, Elisa and Dellwo, Volker},\n\tmonth = nov,\n\tyear = {2018},\n\tpages = {151--174},\n}\n\n\n\n

Here, the influence of talker variability and multiple response options on vowel recognition at high f o s is assessed. The stimuli (n = 264) consisted of eight isolated vowels (/i y e ø ϵ a o u/) produced by three female native German talkers at 11 f o s within a range of 220-1046 Hz. In a closed-set identification task, 21 listeners were presented excised 700-ms vowel nuclei with quasi-flat f o contours and resonance trajectories. The results show that listeners can identify the point vowels /i a u/ at f o s up to almost 1 kHz, with a significant decrease for the vowels /y ϵ/ and a drop to chance level for the vowels /e ø o/ toward the upper f o s. Auditory excitation patterns reveal highly differentiable representations for /i a u/ that can be used as landmarks for vowel category perception at high f o s. These results suggest that theories of vowel perception based on overall spectral shape will provide a fuller account of vowel perception than those based solely on formant frequency patterns.},\n\tnumber = {2},\n\tjournal = {The Journal of the Acoustical Society of America},\n\tauthor = {Friedrichs, Daniel and Maurer, Dieter and Rosen, Stuart and Dellwo, Volker},\n\tyear = {2017},\n\tpages = {1025--1033},\n}\n\n\n\n

Therefore, the foreign accent cues in the stimuli consisted of only temporal information (in a) and only strongly degraded spectral information (in b). Findings suggest that listeners were able to identify the linguistic origin of French and English speakers in their foreign-accented German speech based on temporal features alone, as well as based on strongly degraded spectral features alone. When comparing these results to previous research, we found an additive trend of temporal and spectral cues: identification performance tended to be higher when both cues were present in the signal. Acoustic measures of temporal variability could not easily explain the perceptual results. However, listeners were drawn towards some of the native German segmental cues in condition (a), which biased responses towards ‘French’ when stimuli featured uvular /r/s and towards ‘English’ when they contained vocalized /r/s or lacked /r/.},\n\tjournal = {Speech Communication},\n\tauthor = {Kolly, M.-J.

The German listeners' performance was lower compared to the Spanish listeners but higher than that of the French listeners.

The correlation test showed a significant positive correlation between the ratings of Rater 1 and the variable varcoM (mean intensity variability across syllables). In contrast, the ratings of Rater 2 correlated positive and significantly with two rhythmic measures related to mean consonant duration.

Thereby, the selection of LPC parameters is based on the assumption that the number of poles for the analysis of a given frequency range is age- and gender-specific. However, when crosschecking measured formant tracks with the spectrogram, mismatches occur in a significant number of cases. In these cases, the investigators try to minimize these mismatches by modifying the number of poles of LPC. Such an interaction is based on phonetic knowledge, analytical experience and related expectations. Several authors have pointed towards the lack of objectivity and the inherent circularity as well as the fact that similar formant estimations performed by different researchers may yield different results. As of yet, the issue of an improvement and objectification of formant estimation procedure is still a matter of debate. The present paper describes such a corresponding approach: basing the LPC pole-number selection on objective criteria by introducing Euclidean distance measure and formant frequency conditions as references for interactive formant frequency estimation. The paper further presents and discusses the results of a pilot evaluation using the method proposed on 224 long Standard German vowel sounds /i-y-e-ø-ɛ-a-o-u/ produced by eight children, ten women and ten men on fundamental frequencies of 262 Hz (children), 220 Hz (women) and 131 Hz (men), respectively.},\n\tlanguage = {en},\n\turldate = {2025-04-18},\n\tpublisher = {TUDpress},\n\tauthor = {Kathiresan, Thayabaran and Maurer, Dieter and Dellwo, Volker},\n\tyear = {2017},\n}\n\n\n\n

Such system captures the smoothed amplitude fluctuation pattern over time, illustrating how energy is distributed across the signal. Although the pulmonic air pressure is the primary energy source of speech, the amplitude modulation pattern is largely determined by articulatory behaviours, especially mandible and lip movements. Therefore, there should be a correspondence between signal envelope kinematics and articulator kinematics. Previous research showed that a tremendous amount of speaker idiosyncrasies in articulation existed. Such idiosyncrasies should therefore be reflected in the envelope kinematics as well. From the signal envelope kinematics, it may be possible to infer individual articulatory behaviours. This is particularly useful for forensic phoneticians who usually have no access to articulatory data, and clinical speech pathologists who usually find it difficult to make articulatory measurement in clinical consultations. Also in this paper, we illustrate a correspondence between the amplitude envelope kinematics and the lower lip kinematics (X-ray pellet history data) of one speaker reading one sentence. For future research, more speakers are needed to record both speech and articulatory signals to build a statistical model between the kinematics data of both domains.},\n\tlanguage = {en},\n\turldate = {2025-04-18},\n\tpublisher = {TUDpress},\n\tauthor = {He, Lei and Dellwo, Volker},\n\tyear = {2017},\n}\n\n\n\n

Mean and peak intensity variability across syllables (stdevM, varcoM, stdevP, varcoP, rPVIm, nPVIm, rPVIp, nPVIp; henceforth: intensity measures) were investigated as a function of speaker in a database where within-speaker variability was strong (BonnTempo) and another database designed to examine between-speaker rhythmic variability (TEVOID). It was found that the intensity measures varied significantly between speakers in both databases. Semiautomatic speaker recognition based on duration measures (\\%V, ΔV(ln), ΔC(ln), ΔPeak(ln), ΔSyll(ln) and nPVISyll) and intensity measures using multinomial logistic regression and feedforward neural networks was carried out for the two databases. Results showed that intensity measures contained stronger speaker specific information compared to measures based on durational variability of phonetic intervals. In addition, effects of the recognition algorithms (speaker recognition using multinomial logistic regression was significantly better than neural networks for BonnTempo) and data normalisation procedures (z-score normalised data was significantly better than non-normalised data in TEVOID) were discovered. This means that syllable intensity characteristics play an important role in between-speaker rhythmic differences and possibly in speech rhythm variability in general.},\n\tnumber = {2},\n\tjournal = {International Journal of Speech, Language and the Law},\n\tauthor = {He, Lei and Dellwo, Volker},\n\tyear = {2016},\n\tpages = {243--273},\n}\n\n\n\n

We argue that such intervals stand in close relation to the rhythm of speech as they contribute to the overall temporal organization of the speech production process and the acoustic signal (stable intervals = intervals of reduced movement of certain articulators; unstable intervals = intervals of enhanced movement of certain articulators). To test the relationship of stability intervals with speech rhythm we investigated the between-speaker variability of stable and unstable intervals in the TEVOID corpus. Results revealed that significant between-speaker variability exists. We hypothesize from our findings that the basic segmentation of speech into stable and unstable intervals is a process that might play a role in human perception and processing of speech.},\n\tlanguage = {en},\n\turldate = {2025-04-18},\n\tbooktitle = {Interspeech 2015},\n\tpublisher = {ISCA},\n\tauthor = {Glavitsch, Ulrike and He, Lei and Dellwo, Volker},\n\tmonth = sep,\n\tyear = {2015},\n\tpages = {31--35},\n}\n\n\n\n

Viewing from a lifespan perspective, we recorded the electroencephalogram (EEG) data of three age samples: young adults, middle-aged adults and older adults. Stimuli consisted of temporally degraded sentences in Swedish-a language unfamiliar to all participants. We found age-related differences in phonetic pattern matching when participants were presented with envelope-degraded sentences, whereas no such age-effect was observed in the processing of fine-structure-degraded sentences. Irrespective of age, during speech processing the EEG data revealed a relationship between envelope information and the theta band (4-8 Hz) activity. Additionally, an association between fine-structure information and the gamma band (30-48 Hz) activity was found. No interaction, however, was found between acoustic manipulation of stimuli and age. Importantly, our main finding was paralleled by an overall enhanced power in older adults in high frequencies (gamma: 30-48 Hz). This occurred irrespective of condition. For the most part, this result is in line with the Asymmetric Sampling in Time framework (Poeppel in Speech Commun 41:245-255, 2003), which assumes an isomorphic correspondence between frequency modulations in neurophysiological patterns and acoustic oscillations in spoken language. We conclude that speech-specific neural networks show strong stability over adulthood, despite initial processes of cortical degeneration indicated by enhanced gamma power. The results of our study therefore confirm the concept that sensory and cognitive processes undergo multidirectional trajectories within the context of healthy aging.},\n\tnumber = {3},\n\tjournal = {Brain Topography},\n\tpublisher = {Springer},\n\tauthor = {Rufener, Katharina Simone and Oechslin, Mathias S. and Wöstmann, Malte and Dellwo, Volker and Meyer, Martin},\n\tyear = {2015},\n\tpages = {1--19},\n}\n\n\n\n

Results revealed that overall listener performance was well above chance (mean A'=0.82) while there was no bias for either read or spontaneous speech (mean BD′=0).

Consequently, practitioners often use f0 information in forensic casework. Current research principally examines the use of long-term f0 statistics such as f0 means and standard deviations for forensic voice comparison. The present study investigates how short-term f0 features such as measured by the Fujisaki intonation model capture speaker-individuality. Based on data of a homogeneous group of Zurich German speakers, we conducted an experiment on a large corpus of read speech and on a subset of sentences that included speaking style variability (spontaneous vs read). The latter is characteristic of forensic casework. Speakers demonstrated high between-speaker variability and low within-speaker variability across the two speaking styles for a number of f0 features. Given this evidence of speakerindividuality, we discuss Fujisaki f0 features’ potential for forensic voice comparison.},\n\tlanguage = {en},\n\tnumber = {2},\n\turldate = {2025-04-18},\n\tjournal = {The International Journal of Speech, Language and the Law},\n\tauthor = {Leeman, Adrian and Mixdorff, Hansjörg and O'Reilly, Maria and Kolly, Marie-José and Dellwo, Volker},\n\tmonth = feb,\n\tyear = {2015},\n\tpages = {343--370},\n}\n\n\n\n

Listeners were asked to say whether the two voice samples in each pair were produced by the same or different speakers, and to give a certainty rating. The results showed that speaker discrimination is more difficult in whispered than in voiced speech, and that while the phoneticians were only slightly better than the naive listeners in voiced speech, the gap widened in whispered speech. Phoneticians were more cautious in their responses, but also more accurate than naive listeners. When unsure, the phoneticians tended to say two utterances came from different speakers, whereas naive listeners tended to say two utterances came from the same speaker. Results support the view that trained phoneticians may have an advantage over naive listeners in auditory speaker discrimination when the signal is degraded.},\n\tnumber = {2},\n\tjournal = {International Journal of Speech, Language and the Law},\n\tpublisher = {Equinox Publishing Ltd.},\n\tauthor = {Bartle, Anna and Dellwo, Volker},\n\tyear = {2015},\n\tpages = {229--248},\n}\n

Suppression and congruency effects in audiovisual paradigms with letters and speech sounds have provided information about low-level mechanisms of grapheme-phoneme integration during reading. However, the central question about how such processes relate to reading entire words remains unexplored. Using ERPs, we investigated whether audiovisual integration occurs for words already in beginning readers, and if so, whether this integration is reflected by differences in map strength or topography (aim 1); and moreover, whether such integration is associated with reading fluency (aim 2). A 128-channel EEG was recorded while 69 monolingual (Swiss)-German speaking first-graders performed a detection task with rare targets. Stimuli were presented in blocks either auditorily (A), visually (V) or audiovisually (matching: AVM; nonmatching: AVN). Corresponding ERPs were computed, and unimodal ERPs summated (A + V = sumAV). We applied TANOVAs to identify time windows with significant integration effects: suppression (sumAV–AVM) and congruency (AVN–AVM). They were further characterized using GFP and 3D-centroid analyses, and significant effects were correlated with reading fluency. The results suggest that audiovisual suppression effects occur for familiar German and unfamiliar English words, whereas audiovisual congruency effects can be found only for familiar German words, probably due to lexical-semantic processes involved. Moreover, congruency effects were characterized by topographic differences, indicating that different sources are active during processing of congruent compared to incongruent audiovisual words. Furthermore, no clear associations between audiovisual integration and reading fluency were found. The degree to which such associations develop in beginning readers remains open to further investigation.},\n\tnumber = {6},\n\tjournal = {Brain Topography},\n\tauthor = {Jost, Lea B. and Eberhard-Moscicka, Aleksandra K. and Frisch, Christine and Dellwo, Volker and Maurer, Urs},\n\tyear = {2014},\n\tpages = {786--800},\n}\n\n\n\n

This preserved mainly time domain characteristics and different degrees of rudimentary information from the frequency domain. Results showed that listeners could recognise French- and English-accented German above chance even when their access to segmental and spectral cues was strongly reduced. Different types of temporal cues led to different recognition scores - segment durations were found to be the temporal cue most salient for accent recognition.

Such observations reveal that speakers carry individual features in their voices. The present study examines how suprasegmental temporal features contribute to speaker-individuality. Based on data of a homogeneous group of Zurich German speakers, we conducted an experiment that included speaking style variability (spontaneous vs. read speech) and channel variability (high-quality vs. mobile phone-transmitted speech), both of which are characteristic of forensic casework. Speakers demonstrated high between-speaker variability in both read and spontaneous speech, and low within-speaker variability across the two speaking styles. Results further revealed that distortions of the type introduced by mobile telephony had little effect on suprasegmental temporal characteristics. Given this evidence of speaker-individuality, we discuss suprasegmental temporal features' potential for forensic voice comparison. © 2014 Elsevier Ireland Ltd.},\n\tjournal = {Forensic Science International},\n\tauthor = {Leemann, Adrian and Kolly, Marie José and Dellwo, Volker},\n\tyear = {2014},\n\tpages = {59--67},\n}\n\n\n\n

The normal condition was produced at an average rate of 6.34 syllables/s or 100\\%, the very slow version at 67\\%, and the fastest version at 161\\% of the normal rate. We extracted F0 contours and subjected them to decomposition using the Fujisaki model. We ordered all the data with respect to their actual speech rates. First, we assessed how prosodic realizations vary with speech rate and examined phrase command magnitudes, the number of phrase commands as well as the base frequency, accent command amplitudes, and the timing of accent command with respects to the underlying syllables and their nuclear vowels. Second, we analyzed between-sentence variability within and between speakers and investigated whether and how the prosodic structure is preserved at different speech rates. For very slow speech, we found for some of the speakers that the original phrase structure had disintegrated into something like a list of isolated words separated by pauses. Very fast speech became chains of uniform syllables at very high pitch and with almost flat intonation. With respect to the F0 range reflected by the amplitude of accent commands, we found strong interspeaker differences. While four of the subjects exhibited a significant reduction at higher speech rates, the others did not. As speed increases, it appears that F0 gestures commence earlier in the syllable, that is, the onset time of accent commands is located closer to the syllable/vowel onset than at lower speed.},\n\tnumber = {1},\n\tjournal = {Eurasip Journal on Audio, Speech, and Music Processing},\n\tauthor = {Mixdorff, Hansjörg and Leemann, Adrian and Dellwo, Volker},\n\tyear = {2014},\n\tpages = {1--11},\n}\n\n\n\n

There are some studies on the assignment of word stress by (language impaired) native speakers of German. Janßen (2003) found proof for the quantity-sensitive approach to German when the participants were urged to read out pseudowords. The present experiment is on perception: we presented spoken three syllable pseudowords to healthy participants and instructed them to: (a) remember as many items as they could (memory task), and (b) repeat the words (repetition task). Since regular word stress is assumed to make use of fewer cognitive resources than irregular word stress we expected participants to prefer one specific type of word stress in the memory task as well as in the repetition task. We found a preference for pseudowords stressed on the antepenultima (and penultima), supporting neither quantity-sensitive nor quantity-insensitive approaches, but an alternative approach connecting both approaches.},\n\tnumber = {240},\n\tjournal = {Linguistische Berichte},\n\tpublisher = {Helmut Buske Verlag},\n\tauthor = {Riedl, Lydia and Wiese, Richard and Dellwo, Volker and Wittig, Annika},\n\tmonth = nov,\n\tyear = {2014},\n\tpages = {447--470},\n}\n\n\n\n

We addressed this question by an example of analyzing rhythmic variability between eight dialects of Swiss German in three different sentences. Results showed a significant interaction for dialect*sentence for most of the tested rhythm metrics. We take this as evidence that differences between dialects are contingent upon the sentences used in the experiment. We further investigated which sources in the sentence material caused between-dialect differences in rhythm scores to vary. We found exemplary evidence that dialect-specific phonological and morphological phenomena contained in the individual sentences are the prime suspects.

Four speakers (synchronization speakers) synchronizing to twelve recorded sentences produced by four other speakers (target speakers) were studied.

We show that voice patterns — in terms of vocal fold vibration — provide an effective basis for classification and that they can be automatically processed for large datasets.

Six Cantonese and six Beijing Mandarin native speakers were recorded reading the North Wind and the Sun story with a normal speech rate, telling the story semi-spontaneously and reading the English version of the story. Both raw and normalised rhythmic measures were calculated using vocalic, consonantal and syllabic durations (ΔC, ΔV, ΔS, \\%V, VarcoC, VarcoV, VarcoS, rPVI\\_C, rPVI\\_S, nPVI\\_V, nPVI\\_S). Results confirm the syllabletiming impression of Cantonese and Mandarin. Data of the two foreign English accents poses a challenge to the rhythmic measures because the two accents are syllable-timed impressionistically but were classified as stress-timed by some of the rhythmic measures (ΔC, rPVI\\_C, nPVI\\_V, ΔS, VarcoS, rPVI\\_S and nPVI\\_S).
