Özet

The objective of this study is to analyze and evaluate the acoustic parameters of sustained Turkish vowels. Records had been taken from 17 volunteer adults, of whom expressed that they did not demonstrate any pathologies. Volunteers uttered /a/, /e/, /i/, /o/ and /u/ vowels twice, where the second recordings were made approximately two weeks after the first one. Vowels were recorded and analyzed by using the Kay Elemetrics Multi-Speech (MS) analysis software. The acoustic parameters analyzed were Jitter, Shimmer, Pitch Period and HNR (Harmonic-to-Noise Ratio). The results obtained from the MS software were evaluated against normative values obtained from healthy people. After the parameter analyses, all acoustic parameters for each vowel, obtained from the same volunteer, under investigation (i.e. jitter, shimmer, pitch period, HNR) have been examined by a visual data mining method. The results indicate that there is no significant difference between the first and second recordings for the parameters under investigation. In addition to this important finding, it reveals that one of the vowels is enough for any decision about someone's recordings, except /u/ vowel.
