基于IBM ViaVoice的语音识别系统在上位机和下位机之间的通讯的架构机实现的关键技术机算法！-Based on the IBM ViaVoice speech recognition system in the host computer and the next bit of communication between machines realize the structure of the key technology machine algorithm!

This code is used to remove silence from a voice signal so that the recognition in voice recognition will give good result. The method is Scale on threshold applied to the envelope for detecting scilence periods. The actual threshold is computed by multiplying threshin" by the median value of the envelope samples. The default is (.25), whichis 25 of the median envelope value over input signal .-This code is used to remove silence from a voice signal so that the recognition in voice recognition will give good result.
