The Effect of Voicing on Constriction Duration, Voice Duration and Vowel Duration in Stop and Fricative Consonants of Turkish Language in Tabrizi Dialect

Voicing is one of the most important phonological features in distinguishing consonants in many languages. In this study, we investigated the temporal parameters such as constriction duration, voice duration, and vowel duration in stop and fricative consonants of Azeri Turkish language in intervocalic position (VCV). The main purpose of this study is to study stop and fricative consonants in Tabrizi dialect. An attempt was made to answer the question of how the voicing of stop and fricative consonants of Turkish language affects the temporal parameters. Twelve selected words of Turkish common words were repeated by fourteen Tabrizi speakers. They were produced three times in citation form. The results showed that temporal parameters are considered as potential cues in distinguishing voiced and voiceless Turkish consonants. The results related to stop consonants also showed that only voice duration and vowel duration were effective in the voicing contrast. The results for the closure duration confirmed that there is no significant difference between voiced and voiceless stops and this cue can not be used as a distinguishing cue to voicing in Azeri Turkish stops.
