是的，但是你需要实现它。 您需要获取音频数据的缓冲区并手动检查位。 您可以在一段时间内检测到低水平的声音，如果您达到
那个阈值，则可以确定没有人在说话。 这可能有助于您入门：

Yes it is possible but you would need to implement it.  You would need to get the buffer of audio data and inspect the bits manually.  You could detect a low level of sound over a certain period of time and determine no one is speaking if you hit that threshold.  This might help get you started: http://code.msdn.microsoft.com/Microphone-Sample-b2ebe8b6/sourcecode?fileId=62761&pathId=471639287
