How to turn off the beep for SpeechRecognizer?

Question

This was asked before, but no one seemed to have a solution: Mect SpeechRecognizer Beep Sound

However, I would still like to know if anyone knows how to turn off the beep for SpeechRecognizer?

I am creating a speech recognition object: private SpeechRecognizer sr = SpeechRecognizer.createSpeechRecognizer (this);

And then in my class I create a speech reconnaissance similar to this

sr.setRecognitionListener(new listener()); Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); i.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getApplication() .getClass().getName()); i.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 6); i.putExtra(RecognizerIntent.EXTRA_PROMPT, ""); i.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 7000); sr.startListening(i); 

Anyone with good ideas? I researched that I could create an AudioManager object (AudioManager mAudioManager), and then using setStreamSolo () I could mute the sound. But I'm not sure how to implement this. I added it to my instance code for the speech recognizer, and nothing happened. Is this something I should call from my main class?

 mAudioManager.setStreamSolo(AudioManager.STREAM_VOICE_CALL, true); 

Thanks in advance.

I would comment, but I have no representative. However, I would like to help.

Did you see that:

Is it possible to disable silent mode programmatically in android?

It seems to me that the code differs depending on the version of Android - as indicated in the first link, Google switched the output of the "sound signal" to the media stream .

I assume that one of these issues will have a solution. If so, please write what you did as you stated that many people have a problem.

My suggestion:

 //mute audio AudioManager amanager=(AudioManager)getSystemService(Context.AUDIO_SERVICE); amanager.setStreamMute(AudioManager.STREAM_NOTIFICATION, true); amanager.setStreamMute(AudioManager.STREAM_ALARM, true); amanager.setStreamMute(AudioManager.STREAM_MUSIC, true); amanager.setStreamMute(AudioManager.STREAM_RING, true); amanager.setStreamMute(AudioManager.STREAM_SYSTEM, true); //unmute audio AudioManager amanager=(AudioManager)getSystemService(Context.AUDIO_SERVICE); amanager.setStreamMute(AudioManager.STREAM_NOTIFICATION, false); amanager.setStreamMute(AudioManager.STREAM_ALARM, false); amanager.setStreamMute(AudioManager.STREAM_MUSIC, false); amanager.setStreamMute(AudioManager.STREAM_RING, false); amanager.setStreamMute(AudioManager.STREAM_SYSTEM, false);

In addition, the scope will be prior to launch (i);

With the solution above from Mark you will have a failure with the following description:

 Failure delivering result ResultInfo{ who=@android :requestPermissions:, request=65736, result=-1, data=Intent { act=android.content.pm.action.REQUEST_PERMISSIONS (has extras) }} to activity java.lang.SecurityException: Not allowed to change Do Not Disturb state 

If you just want to turn off the beep for the speech recognizer, you just need to turn off AudioManager.STREAM_MUSIC .

In Kotlin, for me it looks like this:

 object AudioUtils { @JvmStatic fun muteAudio(shouldMute: Boolean, context: Context) { val audioManager: AudioManager = context.getSystemService(Context.AUDIO_SERVICE) as AudioManager val muteValue = if (shouldMute) AudioManager.ADJUST_MUTE else AudioManager.ADJUST_UNMUTE audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, muteValue, 0) } }
