A Chinese aspiration is generally considered to be very difficult to reproduce by Japanese students. We measured the voice on set time (VOT) and mean power during VOT, as the evaluation parameters, of single vowel sounds of alveolar [t] and velar [k] in Chinese aspirations uttered by 40 Japanese students. The sounds were evaluated by the listening test of 8 native Chinese speakers. Then we proved that the VOT was not the sole measure for evaluating the pronunciations but also the mean power during VOT was the other measure for evaluating them. Although we previously reported on the Chinese liberal sounds, we confirmed that the pronunciation with longer VOT was evaluated as being generally good. We found that the students got good marks and easily mastered pronouncing some of the sounds in the study. So we measured the evaluation parameters of the Japanese stop sounds, uttered by 10 Japanese who had not studied Chinese before. Although the VOT was shorter and the power was lower than those of the Chinese aspirations, such Japanese sounds have similar articulation to Chinese aspirations.
