Whereas the participants showed gains in the relatively easy aspect of the English // acquisition (F2 reduction for tongue retraction) as a function of increased L2 input, their explicit awareness of accurate English // pronunciation played a significant role in the acquisition of the relatively difficult dimension (lengthening phonemic duration). The awareness-acquisition link was not found, however, for the most difficult dimension (F3 reduction for labial, alveolar and pharyngeal constrictors) at least within the timeframe of the project.},

A Phonetic Description of the Kawaiisu Language. Thomas, P. N Ph.D. Thesis, University of Arizona, Tucson, 2018.

A Phonetic Description of the Kawaiisu Language [link]

Paper abstract bibtex

This dissertation represents the first acoustic phonetic description of Kawaiisu, an endangered language of the Uto-Aztecan family spoken in the area near Tehachapi, California. The Kawaiisu language is understudied and underdocumented. Although an impressive grammar (with a lexicon and texts) has been published (Zigmond et al. 1990), discussion of the sound system is relegated to only a few pages. The present dissertation expands on the description of Kawaiisu phonetics and phonology contained in Zigmond et al. (1990), finding support for many of the claims made in their grammar. In addition, I show that the phonetic system of Kawaiisu is characterized by rich variation, examining acoustic evidence to illustrate the different ways that Kawaiisu sounds can be articulated. The analyses presented in this dissertation come from recordings made by Sheldon Klein in the 1950s and 1980s (Klein 1958, 1981-1983). Digital versions of these recordings are hosted online at the California Language Archive, and numerous types of data are represented therein: wordlist elicitation, sentence elicitation, traditional narratives, monologues, and conversations in Kawaiisu are all included in the archival data. In this dissertation, I examine words produced in isolation during elicitation sessions exclusively. These data come from four speakers: one male speaker recorded in the 1950s, and three female speakers recorded in the 1980s. From these data, I examine both the consonant and vowel systems of Kawaiisu. Considering vowels, evidence is presented which supports Zigmond et al.’s (1990) claim of a six-vowel system with phonemic vowel length contrast. I also find that an increase in pitch is the most robust acoustic cue to Kawaiisu stress, and that unstressed vowels often lie more toward the periphery of the vowel space than stressed vowels. Additionally, the pervasive phenomenon of word-final vowel deletion in Kawaiisu is examined, claimed by Zigmond et al. (1990) to target verbs specifically. Although word-final vowel deletion is found to be a common process in Kawaiisu, no evidence is found in the available data linking this process to a specific lexical category, and some suggestions are offered for why Zigmond et al. (1990) may have arrived at this conclusion. Concerning consonants, this dissertation provides support for some of the phonological alternations mentioned by Zigmond et al. (1990), including the palatalization of coronal sibilants preceded by front vowels. I also show that many consonants have differing articulations in apparent free variation: the rhotic phoneme of Kawaiisu is variously realized as a flap or trill, while the consonant commonly labeled as /g/ (especially by Zigmond et al. (1990), and Klein (2002)) may often be produced with fricative or approximant articulations, rather than as a stop. Additionally, I show that the glottal stop (both intervocalically and in some cases pre-consonantally) is associated with the presence of creaky voice. Finally, I discuss voice onset time of voiceless stops, finding that VOT is often greater when the following vowel is phonemically long. This research can be useful to both the community of linguists and to the Kawaiisu community. For linguists, this work presents a phonetic description of a language whose sound system was previously not adequately described. Variation in articulation has been noted where acoustic evidence for such variability was found, and several cross-linguistically rare patterns and structures have been indicated (for example, peripherality of unstressed over stressed vowels, the relationship between phonemic vowel length and VOT of stops, etc.). For community members, the information presented in this document can be used to help create pedagogical materials for purposes of language revitalization. Finally, this research highlights the importance of working with existing archival data. Archival language data is available through a number of sources, and in many cases, it may be all that remains of a once widely spoken language. This dissertation shows that important descriptive and documentary work can still be done, both to the benefit of the academic community, and to indigenous speech communities.

La discusión de los resultados de este análisis interlingüístico permite extraer algunas conclusiones potencialmente interesantes para la teoría fonético-fonológica. En concreto, se argumenta que la vocal de relleno puede constituir una unidad acústico-articulatoria claramente diferenciada de las vocales que integran los respectivos sistemas fonológicos y estrechamente relacionada con los ajustes articulatorios propios de cada lengua, esto es, con su base de articulación.},

	Abstract = {Aunque los fenómenos de hesitación en el discurso --pausas sonoras y alargamientos-- se han abordado desde diferentes puntos de vista, son escasos los estudios que analizan sus manifestaciones acústicas en español. En este trabajo se presenta una caracterización preliminar de las hesitaciones que, generalmente, suelen aparecer en el habla espontánea con diferentes funciones discursivas. Se han analizado 180 minutos de conversaciones en las que han participado seis hablantes, con una duración aproximada de 30 minutos cada una, y 30 fragmentos de producción espontánea de un minuto de duración correspondientes a tres sesiones de grabación de 10 locutores. En las primeras se da una interacción entre los participantes, mientras que en las segundas, el hablante sabe que no será interrumpido durante su intervención. El análisis acústico se ha complementado con un estudio perceptivo en el que los oyentes debían valorar la naturalidad y la espontaneidad de los mismos fragmentos presentados con o sin alargamiento y con o sin pausa sonora. Los resultados muestran, en primer lugar, que la pausa sonora más frecuente en español es [e?]. Los valores medios y las desviaciones correspondientes a la duración de los alargamientos y de las pausas sonoras no arrojan diferencias significativas entre estas hesitaciones. No obstante, el rango de los valores medios debería considerarse en la caracterización de tales elementos. Además, los resultados indican que el hecho de que el hablante sepa que no va a ser interrumpido conlleva un incremento de la aparición de hesitaciones en habla espontánea. Los enunciados con pausas y alargamientos se perciben con el mismo grado de naturalidad si se comparan con una versión de los mismos enunciados en la que se han eliminado las hesitaciones, pero no con idéntico nivel de espontaneidad. Finalmente, cabe resaltar que los alargamientos suelen percibirse en el discurso como si el hablante hubiera realizado un silencio.},

	Abstract = {Cases of blackmailing and kidnapping often involve the perpetrator disguising his voice. In the present contribution, we examined the degree to which one exemplary form of voice disguise -- the imitation of a foreign dialect -- affects suprasegmental temporal features. Results of two production experiments and one perception test revealed high between-speaker and low within-speaker variability across the disguise condition. Results from the perception test further underlined the difficulty of the imitation task, as the majority of speakers were not accepted as native speakers by listeners of the target dialect. At the same time, the high rate of rejections of imitations as authentic speech indicates a high sensitivity and dialectal awareness on the part of the listeners. Findings suggest that those imitators who were accepted as native speakers may have been accepted partly because they succeeded in adjusting speaking rate and global intensity peak variability to that of the target dialect, amongst other factors.},

El objetivo de este estudio es evaluar su potencial discriminante y, en consecuencia, su utilidad en la comparación forense de voces con el fin de lograr identificaciones de voz robustas. Para ello, se han analizado variables relacionadas con la estructura de formantes y la cualidad de voz de esta clase de pausas. Los resultados muestran que las variables referentes a la cualidad de voz son más discriminantes que las variables referentes a su estructura de formantes. Además, el estudio conjunto de todas las variables logra mejores resultados que cuando las variables se analizan independientemente. En el caso de utilizar un corpus indubitado de tipo cerrado se logra un 90\% de clasificaciones correctas.},

	Abstract = {word like Huh?--used as a repair initiator when, for example, one has not clearly heard what someone just said-- is found in roughly the same form and function in spoken languages across the globe. We investigate it in naturally occurring conversations in ten languages and present evidence and arguments for two distinct claims: that Huh? is universal, and that it is a word. In support of the first, we show that the similarities in form and function of this interjection across languages are much greater than expected by chance. In support of the second claim we show that it is a lexical, conventionalised form that has to be learnt, unlike grunts or emotional cries. We discuss possible reasons for the cross-linguistic similarity and propose an account in terms of convergent evolution. Huh? is a universal word not because it is innate but because it is shaped by selective pressures in an interactional environment that all languages share: that of other-initiated repair. Our proposal enhances evolutionary models of language change by suggesting that conversational infrastructure can drive the convergent cultural evolution of linguistic items.},

For this purpose we analyzed the spectral information of the vocalic fillers by estimating their first two formant frequencies as well as their duration properties. The vocalic fillers are taken from a large corpus of European Portuguese broadcast news' speech. We also compared the vocalic fillers with lexical vowels possessing similar timbre. No formant variation trend was attained for the vocalic fillers and a great overlap of formant values is observed. These results provide a base of information for understanding the most common vocalic fillers in European Portuguese spontaneous speech.},

We especially investigate duration, fundamental frequency, and first two formant analyses. Most frequent hesitations can be expressed by lengthened phonemes such as /ää/, /ee/, /õõ/, and /mm/. We compare lengthened phoneme hesitations with their related phonemes. The results from our preliminary hesitation study show (i) hesitations have longer duration and its range is spread; (ii) hesitations globally include lower pitch; (iii) hesitation formants are likely to be centralized or posterior and opened in comparison with related phonemes.},
