Research Abstract

A Chinese aspiration is generally considered to be very difficult for Japanese students to reproduce and perceive. We measured the voice on set time (VOT) and mean breathing power during VOT, as evaluation parameters, of diphthong sounds of the labial of pai[p'ai], pao[p'ao], pei[p'ei] and pie[p'iε] diphthong sounds of the alveolar of tai[t'ai], tao[t'ao], tie[t'iε], and tou[t'ou], diphthong sounds of the velar of kai[k'ai], kao[k'ao], kie[k'iε] and kou[k'ou] uttered by nine Japanese students and nine native Chinese speakers. Then, we found that the VOT was not t+he sole measure for evaluating the pronunciations ; the mean breathing power during VOT is also a useful measure for evaluation. In order to offer an instruction tool for students for their private study, we designed the automatic measurement system of VOT and relative breathing power. And we apply it to the uttered sounds of above diphthong syllables and examine the performance of the system. The result shows that the averaged recognition rates are 85% and 76% for each syllable of unaspirated and aspirated, respectively.
