How can I save TTS output in an audio file on andr

问题:

this is my first post here. I'm new in Android Programming. I want to create an app where I can save the output of the text to speech into an audio file to my database. I've heard about synthesizeToFile() but It's not it.

Use this code and get the mp3 file acess from the assets folder and try this code.

mMediaPlayer = new MediaPlayer();
mMediaPlayer = MediaPlayer.create(this,R.raw.button);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.start();
mMediaPlayer.setOnCompletionListener(new OnCompletionListener() {                   
    @Override
    public void onCompletion(MediaPlayer mp) {
        mMediaPlayer.stop();
    }
});

synthesizeToFile() should create a wav (which you can decode and send to your db or save as a file or whatever you're doing with it), and you can play it back using Nitesh's code.

From http://android-developers.blogspot.fi/2009/09/introduction-to-text-to-speech-in.html:

HashMap<String, String> myHashRender = new HashMap();
String wakeUpText = "Are you up yet?";
String destFileName = "/sdcard/myAppCache/wakeUp.wav";
myHashRender.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, wakeUpText);
mTts.synthesizeToFile(wakeUpText, myHashRender, destFileName);

Once you are notified of the synthesis completion, you can play the output file just like any other audio resource with android.media.MediaPlayer.

You should be saved in the tts file assets folder.
