Acoustic features of dysphonic speech vs normal speech in New Zealand English speakers

Abstract

This poster presents the acoustic features of distorted speech in three dysphonic New Zealanders compared to three healthy individuals as the control group. There are a total of six subjects in this study. Voice onset time and measurements of the two formant frequencies of vowel articulation in /hVd/ words are calculated for both groups, and the results are provided for comparison purposes. Furthermore, independent sample t-tests are conducted between dysphonic and normal speech results to evaluate the significancy of the differences in acoustic measurements.
