Android语音识别立即停止

Question

我基于Android网站上的一个示例开发了一个功能完备的语音识别程序。

我没有改变代码，它只是突然停止工作。它开始听（你可以听到噪音），然后立即停止（你听到结尾的噪音）。

有没有其他人有这个问题或有任何想法我可以解决它？这里是代码，运行时没有输出错误，只是监听器在开始监听时几乎立即停止。

    Log.i("SRL", "onBeginningOfSpeech");

UPDATE：

翻翻我发现onRMSChanged持续运行的应用程序日志。这是否意味着语音识别也会持续运行，从而导致我的应用程序不能接听任何语音？

看来解决方案是确保设备连接到互联网。我认为TTS引擎需要在更改时连接到正确的互联网主机，因此如果没有互联网连接就不会听。
