摘要
利用小波变换多分辨率分析的特点对汉语语音信号进行分析，成功地提取了一个反映声母和韵母之间过渡段信息的特征参数—过渡帧，利用该参数进行声／韵切分通过对３８９个音节的实验，结果表明。
In this paper,the multiresolution representations of wavelet transform are applied to analyze Chinese speech signals,and a good parameter-transition frame (marked as mixframe)is extracted,which can express the information of the transition period of a Chinese syllable successfully.Depending on this parameter of speech signals,the division between the consonant and the vowel of a Chinese syllable is achieved.With 389 experiments,results show that the wavelet transform can catch the transition information of a Chinese syllable more accurately.
