摘　　要：我们介绍的聋儿语言康复训练系统 ,采用了小波变换的方法 ,较好的描述了语言信号的时变特性 ,提高了语音谱图的分辨率 ,突出了语音信号的特征。该系统显示的语音图谱信息便于聋儿观察理解 。In the languange healing sysem of deaf children, the wavelet transform method is employed to describe the time varying characteristics of speech signals, improve the resolution of speech spectrum and make the speech characteristics more obvious. The speech spectrum information shown in this system is easier for deaf children to observe and understand and it is of great importance to the language healing of deaf children.
