| 摘 要： | 提出一种在5410A-AIC23B上实现实时语音端点检测的方法。采用TLV320 AIC23B音频芯片与DSP实现无线连接，通过计算每帧输入信号的短时能量和过零率，根据计算的特征参数综合判断输入信号是否为语音信号。该方法已成功运用到某项目上，用户还可根据自己的需要提取输入信号的不同特性值并应用于自己的系统中。

| Abstract: | Put forward a method of realized real time voice activity detection on 5410A＋AIC23B. Using TLV320 AIC23B acoustic frequency chip and DSP realized radio catenation, according to calculation short time energy and rate of passing zero for per frame input signal, decision signal is voice signal through characteristic parameter. The method has apply to certain item is succeed. |
