Abstract
Purpose: 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. One of the temporal variable is vowel duration. Vowel duration is a feature that demonstrates between nature of phonation differences in stutterers and nonstutterers. The aim of this study was to study and compare the vowel duration in stutterers and nonstutterers. Methods: 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. Afterward, its summary and fluent speech from three contexts were selected and recorded by praat software and duration of vowels was computed via spectrogram. Results: Independent t test showed that stuttering (P=0.21) and age (P=0.061) did not have significant effect on vowel duration. However these values were higher in stutterers than nonstutterers. Conclusion: This study showed that stuttering does not influence the vowel duration.
