汉语声调具有重要的区别字义的功能,模式言语助听装置正是为极重度聋人感知高频辅音和基频信息而设计。本文就模式言语助听下的汉语普通话声调识别进行系统测试。结果发现,听力正常者在自然语音无听力放大条件下和在模式言语助听下,其声调错误识别率无显著差异。说明模式言语提供的正弦化基频信息可为听力正常者感知成声调信息。极重度聋人在模式言语助听下声调错误识别率较在传统助听下有显著降低,说明模式言语助听能为极重度聋人提供更易分辨的声调信息,有助于提高他(她)们的看话能力,是其实现听力语言康复的有效手段之一。
Chinese tone has the important function of distinguishing semantics, and model speech aids are designed for the perception of high frequency consonants and fundamental information for very severely deaf people. This article conducts a systematic test of Chinese Mandarin Tone Recognition under the mode of speech support. The results showed that there was no significant difference in tone misrecognition rate among normal hearing persons under the condition of no audible amplification of natural speech and that of modal speech. Explain that the modeled speech provides sinusoidal fundamental information which can be perceived as tone information by normal hearing people. Compared with the traditional hearing aids, the recognition rate of tonal errors in the deaf people with severe deafness is significantly lower than that in the traditional hearing aids, indicating that the modal hearing aid can provide more easily deaf tone information for the very deaf people, Their reading ability is one of the effective ways to achieve language rehabilitation in hearing.
