The MediaPlayer does not provide this feature but SoundPool has this functionality. The SoundPool class has a method called setRate (int streamID, float rate). If you are interested in the API have a look here.

This Snippet will work.

 float playbackSpeed=1.5f; 
 SoundPool soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 100);

 soundId = soundPool.load(Environment.getExternalStorageDirectory()
                         + "/sample.3gp", 1);
 AudioManager mgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
 final float volume = mgr.getStreamMaxVolume(AudioManager.STREAM_MUSIC);

 soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener()
 {
     @Override
     public void onLoadComplete(SoundPool arg0, int arg1, int arg2)
     {
         soundPool.play(soundId, volume, volume, 1, 0, playbackSpeed);
     }
 });
