- 端点检测是指用数字处理技术来找出语音信号中的各种段落(如音素、音节、词素、词等)的始点和终点的位置。语音段起止端点检测是语音分析、语音合成和语音识别中的一个必要环节。传统的端点检测方法是从wav文件中获取语音采样,将其分帧并计算短时能量和过零率参数,然后进行端点检测。这种工作方式被称为离线处理方法 ,无法实现语音信号的实时处理,对于语音信号分析具有一定的局限性。本文通过开发ActiveX控件,在MATLAB环境下将其嵌入到figure

过零率计算源代码
- 语音端点的检测,不能只以能量的大小进行检测。人声和周边噪音,都可能拥有足够的能量,因此单独能量无法准确检测端点。而过零率在这一点上,则可以起到很大的效果。因此,端点检测时,过零率是不可以缺少的。(Adding zero crossing rate, can accurate detect. Human speech has more zero crossing rate.)
