Independent t test showed that stuttering (P=0.21) and age (P=0.061) did not have significant effect on vowel duration. Afterward, its summary and fluent speech from three contexts were selected and recorded by praat software and duration of vowels was computed via spectrogram. The present study was descriptive and analytic and 22 stutterers and 22 nonstutterers participated and were asked to read a text that contains three contexts cv, cvc, cvcc and 6 vowels. The aim of this study was to study and compare the vowel duration in stutterers and nonstutterers. Vowel duration is a feature that demonstrates between nature of phonation differences in stutterers and nonstutterers. One of the temporal variable is vowel duration. 137–141.Some of researchers define stuttering as a disorder in timing feature between acoustic elements and interruption in successful and simultaneous programming of speech muscles movements for a word production. The results showed that the durations of the vowels of Wolaytta Doonaa have significant variation due to the tongue height and the tongue advancement, thus, as.

Formant measurement was done with Praat (Boersma and Weenink. In: TRASP 2013, Aix-en-Provence, France, pp. 81) (2) vowel duration is the main determinant of the extent of vowel reduction (p. Specifically, vowel space distortions, resulting in spectral overlap (i.e., overlapping boundaries of neighboring vowels), may differentially. Xu, Y.: ProsodyPro - a tool for large-scale systematic prosody analysis. Whereas vowels produced by individuals with dysar-thria may be characterized by articulatory undershoot, the working space of vowels may be differentially affectedby the nature of the production deficit. The end of the vowel is marked by three co occurring events: 1) a dramatic change in amplitude in the waveform, 2) a change in the energy in the formants accompanied by a change in complexity in the waveform indicating a loss of energy in F2 and F3, 3) th.

Tokens whose vowel duration was more than three standard deviations from the talker’s mean vowel duration were excluded from the anal-ysis (462 tokens), leaving 3,796 tokens for analysis. The duration of the target vowels and prosodic annotations were automatically extracted from the TextGrids. Song, Y.: On experiment of entering tones in Nanjing Dialect.
