VQ在语音识别中的应用，选取十个语音，分别进行训练和测试，实验效果不错，值得学习(VQ in speech recognition, the application of selected ten voice, for training and testing respectively, the experimental effect is good, is worth learning)

This letter presents a novel algorithm to compute the instantaneous frequency (IF) of a multicomponent nonstationary signal using a combination of fractional spectrograms (FS). A high resolution time frequency distribution (TFD) is defined by com-bining FS computed using windows of varying lengths and chirp rates. The IF of individual signal components is then computed by applying a peak detection and component extraction procedure
