语音信号的短时分析，主要包括：分帧、短时能量、短时平均幅度、短时过零率、短时自相关函数、短时幅度差、倒谱、复倒谱、lpc系数、lpc谱估计等-Short-time speech signal analysis, mainly including: sub-frame, short-time energy, short-term average, short-time zero-crossing rate, short-time auto-correlation function, short-t

语音信号的短时能量计算，可以计算语音信号的短时能量，在不同窗口形状与长度下-Short-term energy of the speech signal, can calculate the time speech signal energy at different window shapes and lengths
