Each voice has a speech signal endpoint, determine the start point and end point in complex background noise environment to distinguish between speech signals and voice signals or non. It can efficiently realize the voice transmission, storage or through voice implementation person and machine alternation. Endpoint detection in speech signal processing is an important research topic in the field of. In practical application process, first of all, usually the system requirements of the input signal is judged. Use of endpoint detection methods to accurately identify the speech signals the start point and end point. Only in this way can collect real voice data, thereby reducing the amount of data and computation, thereby reducing processing time, improving the transmission efficiency of the objective. 望采纳!借鉴了一下翻译,自己翻译了一下,差不多是这样。
