Description: 本程序将指定的16K采样的语音数据文件转换为经G.723编解码后的8K语音数据。降采样前先使用180阶的FIR滤波器对语音数据进行频率压缩，然后进行抽取，并对抽取的数据进行G.723编解码。该程序在非特定语音识别的库文件处理中使用，也可扩展至其他用途。-this procedure will be designated the 16K sampling voice data files converted to G.723 codecs by the 8K words Music data. Sampling down before use 180 bands FIR filter frequency voice data compression, then proceed to collect, also collected data G.723 codecs. The procedures in non-specific voice recognition for the use of document processing, and can be expanded to other uses.
