| Abstract | The purpose of this investigation is to analyze the formant structure of vowels produced by stutterers and treated stutterers, by comparing their data with those of control subjects. Moreover, we will study the effects of speech rate increase on the formant structures of the vowels, and that of the three groups of speakers. We chose to analyze French oral vowels [i, a, u], from spectographic data, in two speech rate conditions: normal and fast. By studying these vowels, it becomes possible to explore the limits of the maximum vocalic space, since their productions would reflect maximum articulatory abilities of a speaker, in producing vowel gestures. The three vowels were introduced in [CV] syllables where [C] could be [p], [t] or [k] in order to observe for contextual influences. The sequences were placed in sentences which were repeated ten times by stutterers, treated stutterers and control subjects. Concerning control subjects, several studies (Lindblom, 1963 for example) have shown that an increase of speech rate could provoke a compression of durations and a reduction of the vowel space, i.e. a certain centralization of vowels in this space. However, this phenomenon of centralization was only observed for two vowels, i.e. for [i] and for [u]. What would the result be for stutterers or former stutterers, knowing that the majority of studies |
