Abstract

In this research, we investigated the glottal wave of Persian vowels, using electroglottography. In the first level, the properties of vowels glottal wave were analyzed. In the second level, the glottal wave between male and female speakers were  compared. Contact quotient is the glottal wave parameter which was analyzed. Data included six Persian vowels and the glottal wave recorded using electroglottography. Speakers included four men and four women. The results showed that the average ratio of the Persian vowels contact quotient was significantly different. This result is based on the interactive approach of the linear source-filter model of speech production regarding effect of different areas of speech production. The comparison of male and female speaker glottal waves showed that Contact quotient parameter was different between men and women. In other words, men and women, in addition to the difference in fundamental frequency, showed different voice quality in speech production.
