| 摘 要： | 小波变换是采用多分辨率的思想,非均匀的划分时频空间,对信号做多尺度分析,其功能相当于用一组恒品质因数Q的带通滤波器做多分辨率分析.文章利用小波变换代替带通滤波器组实现电子耳蜗CIS语音信号处理,讨论了小波变换在电子耳蜗CIS语音信号处理中的应用,并对该方法进行计算机仿真和声音合成.

| Abstract: | As a method based on multi-resolution, wavelet transform divides the spatial-temporal field unequally and can be used to analyze the speech signal with multi-resolution. Its function equals the analysis of the speech signal with multi-resolution by using a set of constant quality band-pass filters. This paper employs wavelet transform to implement CIS speech signal processing for cochlear implant instead of band-pass filters. The application of wavelet transform in CIS speech signal processing is discussed, and computer-based acoustic simulation of CIS speech signal processing is also presented. |
