目前讲汉语普通话人工耳蜗（cochlear implant, 简称CI）使用者的声调感知及音乐感知较其他言语感知能力仍不理想。已有研究表明声调与音乐的声学信息特征存在一定相似性，因此我们设想CI使用者的声调感知及音乐感知可能存在一定相关性，并且我们已有对CI使用者音乐感知的研究表明，适当音乐旋律训练可以显著提高其音乐感知能力，进而我们设想是否可通过音乐旋律训练达到提高CI使用者声调感知的目的。除了音乐旋律训练，通过对声音信号的处理也有望提高CI使用者的音乐感知能力。本课题测试CI使用者在安静环境下的汉语普通话声调识别、中文短句识别、音乐旋律识别进行评估，通过设定对照组明确CI使用者的声调感知及音乐感知间的相关性及音乐旋律训练在提高音乐感知的同时是否也可提高声调感知。此外，基于对CI语音处理技术的初步研究，通过优化声信号的传输和接收，探究动态低通滤波技术是否可提高CI使用者音乐感知。

Most cochlear implant(CI) users are capable of good speech understanding in quiet. However, It remains difficult for CI users in competing listening condition (e.g., Mandarin tone recognition, music perception). Studies have showed that Mandarin tone and music may share the similar acoustic information.So the relationship between Mandarin tone recognition and music perception attracts our attention. Still our preliminary study showed moderate music training can improve CI users' music perception performance.So we hypothesize that moderate music training may also improve CI users' Mandarin tone recognition performance.Besides music training, CI users' music perception performance can also be improved by signal processing.The Mandarin tone recognition, sentence recognition and music contour identification will be tested in our study. The relationship between Mandarin tone recognition and music perception performance will be explored. Also, whether music training will benefit the Mandarin tone recognition score will be studied. In addition, based on the acoustic input signal pre-processing and processor parameter optimizing,the idea whether the dynamic low-band filter will benefit the performance of music perception performance and Mandarin tone recognition will be further explored.
