摘要
首先讨论了人类听觉信号处理的原理，进而将基于听觉模型的子波变换（ＷＴ）与短时傅里叶变换（ＳＴＦＴ）进行了比较，突出了ＷＴ信号处理的独特之处。然后，简要讨论了其在语音处理中的应用。最后，给出了应用ＷＴ来进行声、韵母划分和音素周期检测的实验，其结果显示了ＷＴ在语音处理中的良好性能。
First discuss the principle of human auditory signal processing,and then compare WTbased on auditory model with STFT in urder to emphasize the distinet properties of WT. Afterthat, the authors present WT'S application to speech processing. Finally, the experiments inclassification of CN and detection of period of pitch are carried out by using WT. The resultsshow that WT has excellent performances in speech processing.
