Etude de la structure formantique des voyelles produites par des locuteurs

The aim of this study is to analyse the steady—state
portion of the first two formants (F1) and (F2) in the
production of [pVp] sequences, containing vowels [i, a, u]
pronounced in two speech rates (normal and fast) by
groups of untreated and treated stutterers, and nonstutterer
controls. Comparing data between treated or untreated
stutterers and controls, a reduction of vowel space is
observed for stutterers in a normal speaking rate. When
speech rate increases, no reduction of vowel space is
noticeable for untreated stutterers, contrary to treated
stutterers and controls.
