Android TextToSpeech Rate, Sound speaker

Question

I have made an app using TextToSpeech Class.. But the voice rate is too slow .. How to increase the rate of Voice..

Secondly the voice comes from the main(small) speaker.. I want that the Sound Should come from the back speaker(LoudSpeaker).

Answer 1

1) Use function setSpeechRate to make voice faster

Speech rate. 1.0 is the normal speech rate, lower values slow down the speech (0.5 is half the normal speech rate), greater values accelerate it (2.0 is twice the normal speech rate).

2) Use function setSpeakerphoneOn to turn On rear Speakerphone.

AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
audioManager.setSpeakerphoneOn(true);
