- 自动估测语音信号的基音频率。目前只能估计浊音，清音没有基音周期（会报错），基音周期取第二、三帧及以后的帧数。003和191分别是男声和女声的语音信号包。-Automatic estimation of the pitch frequency of the speech signal. Currently only estimated voiced, unvoiced no pitch (being given), take the second pitch, and after three fr

speech_vad
- 利用MATLAB来实现语音的分帧及语音端点检测(Using MATLAB to achieve voice segmentation and voice endpoint detection)
endpoint_detection
- 对传输的语音信号进行端点检测，检测出端点后可进行加窗分帧而后进行短时傅里叶变换。(After the endpoint detection of the transmitted speech signal, after detecting the endpoint, windowed sub frame can be added, and then the short-time Fu Liye transform can be carried out.)
vad
- 可对一段信号进行分帧加窗，利用过零率和短时能量检测语音端点(It can divide the frame into a window and use the zero crossing rate and short time energy to detect speech endpoints.)
