汉语、英语听感知差异及适合汉语的人工耳蜗编码策略

The auditory perception differences between Chinese and English and a new coding strategy of cochlear implants for Chinese

汉语属于声调语言,英语属于重音语言,它们在声学和语音学层次上有着明显的不同。心理声学的研究结果表明汉语与英语在听感知上存在着差异。然而,目前辅助听力康复的电子产品,如人工耳蜗等,都是针对西方语言开发生产的,并不完全适用于说汉语的中国人。本文介绍了汉语和英语听感知差异的研究进展,并提出了针对汉语的人工耳蜗编码策略。

Characterized as a tonal language, Chinese is noted to be greatly different from English in acoustics and phonetics. The research results of psychoacoustics have showed that there are differences in the auditory perception between Chinese and English. Nowadays, most hearing devices are generally designed for hearing-impaired people using western languages and those imported devices are not effective for Chinese speakers. In this paper, some new findings on the auditory perception differences between Chinese and English will be shared and a new coding strategy for cochlear implants will be introduced. The subjective and objective evaluations have demonstrated that it is a valuable candidate for Chinese speakers.
