Acoustic Attributes of Citation Tones in Standard Chinese Produced by Prelingually Deaf Adults
Abstract
―Based on perception judgment and acoustic analysis with the data of ten prelingually deaf adults (PDAs) and ten normal hearing adults (NHAs), the present paper investigated the performance of the four citation tones in Standard Chinese produced by prelingually deaf adults. Overall, the error rate of perception judgment for PDAs was 12.95 %; however, the error rates of Tone 2 and Tone 3 were 30.70% and 19.85% respectively, which were much higher than that of Tone 4 and Tone1. As the results of acoustic analysis, although the general performance of the deaf females was significantly different from NHAs, they approached or reached the level of the control group on some parameters, while deaf males faced greater challenge than deaf females. Therefore, this study confirmed that PDAs still have some impairments on tone production of Standard Chinese.
