[The influences of vowel ae and a: on acoustic measures].
OBJECTIVE
To study the influences of vowel ae and a: on acoustics measures.


METHODS
Fifty-three cases of laryngeal diseases were measured acoustically. The acoustic sampling were vowels ae and a:.


RESULTS
The results showed that Fo, Jitter and Shimmer were similar between two groups, and NNE of vowel a: was much lower than that of ae, indicating larger glottal closure in vowel a:.


CONCLUSIONS
Vowels have something to do with glottal closure, therefore influencs acoustical measures.
