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.
