The Activity of the Cricothyroid Muscle and the Intrinsic Fundamental Frequency in Danish Vowels [link]Paper  doi  abstract   bibtex   
The relationship between the electromyographic (EMG) activity from the pars obliqua of the cricothyroid (CT) muscle (recorded with bipolar hooked-wire electrodes) and the intrinsic fundamental frequency (IF₀) in high and low vowels in Danish was investigated. The test material, which consisted of 306 randomized natural words of the type CV(:)l3, imbedded in carrier sentences, was recorded by 4 native speakers of Danish. The following vowel pairs were compared: [‘i-’a, ‘i :-’æ:, ‘u :-’æ:] and [‘i :-’a]. The results, which are based on visual inspection of average EMG and fundamental frequency (F₀) curves, show a positive correlation between the CT activity and IF₀, more specifically that the CT activity rise related to the high vowels starts earlier and in most cases more steeply than the CT activity related to the low vowels. However, a drop in F₀ at the beginning of the low vowels cannot be accounted for by CT activity. This F₀ drop is believed to be the result of either tongue retraction during the articulation or influence from the preceding consonant. The following conclusion is drawn: The CT muscle is a major factor in controlling IF₀ in stressed high and low vowels in Danish.
