In tab WebRTC GW the right abbreviation has been put: WebRTC GW. The VAD code is part of the much, much larger WebRTC repository, but it's very easy to pull it out and compile it on its own. It allows communication between browsers. Samples Application flow. Media capture devices includes video cameras and microphones, but also screen capturing "devices". 端点检测 ( VAD )采用短时幅度和短时过零率相结合。 检测出有效 后，根据人耳听觉感知特性,计算每帧 的Mel频率倒谱系数 (MFCC)。 然后采用动态时间弯折 (DTW)算法与特征模板相匹配,最终输出识别结果。 先用Matlab对上述算法进行仿真，经多次试验得出算法中所需各系数的最优值。 然后将算法移植到STM32嵌入式平台，移植过程中根据嵌入式平台存储空间相对. kandi ratings - Low support, No Bugs, No Vulnerabilities. tree: dad456278cbfe534447b79193f3dd06cc4ce1edf [path history] [].
