How to set the volume for the "talking" text-to-speech method?

Question

I'm lost. I want to adjust the volume of conversations. Whatever I do, I cannot increase its volume. How to make it as loud as in the Android settings (as shown below)?

System settings → Voice input and output → Text to speech settings → Listen to an example

My code at the moment:

AudioManager mAudioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE); mAudioManager.setSpeakerphoneOn(true); int loudmax = mAudioManager.getStreamMaxVolume(AudioManager.STREAM_NOTIFICATION); mAudioManager.setStreamVolume(AudioManager.STREAM_NOTIFICATION,loudmax, AudioManager.FLAG_PLAY_SOUND); mTts.speak(name,TextToSpeech.QUEUE_FLUSH, null); 

Answer 1

Try using AudioManager.STREAM_MUSIC when calling the setStreamVolume(...) method. In a speech example, the volume of the multimedia affects if I adjust the volume of music on my phone, so I think STREAM_MUSIC is what you need.

EDIT: This code works great for me ...

 AudioManager am = (AudioManager)getSystemService(Context.AUDIO_SERVICE); int amStreamMusicMaxVol = am.getStreamMaxVolume(am.STREAM_MUSIC); am.setStreamVolume(am.STREAM_MUSIC, amStreamMusicMaxVol, 0); tts.speak("Hello", TextToSpeech.QUEUE_FLUSH, null); 

The maximum volume for STREAM_MUSIC on my phone is 15, and I even checked this by replacing amStreamMusicMaxVol with my call am.setStreamVolume(...) above with values ​​of 3, 6, 9, 12, 15 and speech volume correctly set.

Answer 2

In your code, you change the volume of notifications. Is the TTS volume reproducible at the same volume level as the notifications? I suspect this is not the case, and he probably played either STREAM_SYSTEM or STREAM_MUSIC Try changing the stream type to one of the following:

 STREAM_VOICE_CALL, STREAM_SYSTEM, STREAM_RING, STREAM_MUSIC or STREAM_ALARM
