Hello guys,

How to get a speech (TTS) only for right or left channel?
Because I need use the Left channel to speech and the right channel to play music, but the voice can not out over music channel.

MediaPlayer do it by setVolume, L==>0 or R==>0

For music I use a MediaPlayer1 with R=0, L=1 and for voice, MediaPlayer2 with R=1, L=0,
this works fine, but I would like to know about TTS.
Because for MediaPlayer I need files, but this limits the app and results in large apk.

Thank you.
