Android的语音到文本（语音识别，语音） [英] android speech to text (speech recognition ,voice)

问题描述

我想问我怎么可以使用语音文本code对我的模拟器。我的$ C $在实际设备CS工作，但不能在模拟器上工作。错误说：

 无活动处理意向{行为= android.speech.action.RECOGNIZE_SPEECH（有群众演员）}
 

我该怎么办？

I want to ask how I can use speech to text code on my emulator. My codes work on real device but not work on emulator. The error said :

 No Activity found to handle Intent { act=android.speech.action.RECOGNIZE_SPEECH (has extras) }

What can I do?
