对动态力信号的时域特征进行提取包括谐波特征，能量特征和小波特征等-Characterized in the time domain dynamic force signal feature extraction, including harmonics, energy and wavelet characteristics

将原始语音经过预处理,利用频率弯折小波进行特征提取,不错的源码(The original speech after preprocessing, the use of frequency bending wavelet feature extraction, good source)
