摘要
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 lexical tones have an important role in speech recognition, but it is hard to be erceived through speechreading by the profoundly hearing impaired. The speech pattern detection aid (SPDA) is designed for profoundly hearing impaired listeners to perceive consonants and tones. Chinese Pu Tong Hua tones recognition tests were performed systematically in this study. The results showed that the rate of erroneous response to tones aided by SPDA was close to that with the help of conventional hearing aid for the subjects with normal hearing. It revealed that sinusoidal foundametal frequency could be perceived as tones by listeners with normal hearing. For profoundly deaf subjects, the rate of erroneous response to tones under the aid of SPDA was much lower than that with the help of conventional hearing aid. Therefore SPDA could provide more clear tones for profoundly hearing imparied people in speech communication, enhance the ability of speechreading. SPDA is one of effective measures for hearign and speech rehabilitation.
