Influence of prosodic information on the discrimination of vocal quality.

通过几个实验，考察了说日语和英语短句的日本人和北美/英国人的音质识别。研究发现，尽管说话者的声音评分受到其所说语言的显著影响，但对说话者的日语或非日语的辨认速度相当高。有人认为，说话人的音质识别应该受到说话人所说语言的韵律的很大影响。进一步研究了发音质量记忆与说话人所说语言的关系。参与者对演讲者的声音质量进行评分(第一次)，一周后，再次进行同样的实验(第二次)。不考虑一周的空白，这些声音的评级彼此没有什么不同。

Recognition of vocal qualities of Japanese speakers and North American/British speakers who speak several short sentences in Japanese and in English was examined by carrying out several experiments. It was found that the identification of a speaker as Japanese or as non-Japanese was done at a rather high rate, although the ratings on the speaker's voice were significantly influenced by the language that he was speaking. It was suggested that recognition of vocal quality of a speaker should be greatly influenced by the prosody of the languages spoken by the speaker. The relationship between the memory of vocal quality and the language spoken by the speaker was further investigated. Participants rated the vocal quality of a speaker (the first session) and after one week the same experiment was again conducted (the second session). The ratings of the voices were little different from each other, irrespective of one-week blank.
