How to Stop Recognition

[shaohui93]

I use SpeechRecognitionClient examples for speech recognition. How do I stop active recognition?
Here's the code I started identifying.
mSpeechClient.streamingRecognizeCallable()
.bidiStreamingCall()

I stop with the following code, an exception appears, and then I can't recognize it again.、
mAudioEmitter?.stop()
mAudioEmitter = null

Abnormal information is as follows
an error occurredio.grpc.StatusRuntimeException: CANCELLED: Failed to read message.

Actively stop recognizing if something needs to be done
