TTS tone - Android?

I'm making use of Text to Speech - TTS in my Android app.. I've pasted the code below.. TTS is working fine, however the voice/text it speaks is not very clear.. It speaks really quick, so that it is not fully understandable.. I tried setting Locale.US, and used setPitch or setSpeechRate but it is not really convincing. I felt that there is some problem with my phone (Samsung S2).. So tried installing Google Translate TTS app from Google Play store.. In that app the voice was really clear.

My app will be used by Kids.. so want to make sure that the voice is really clear. I'm breaking my head for the past few days to fix this problem.. Would be great if you could give me some pointers on where I'm doing wrong or how to improve??

@Override
public void onInit(int status) {

    if (status == TextToSpeech.SUCCESS) {

        int result = tts.setLanguage(Locale.getDefault());

        //tts.setSpeechRate((float) 0.8);
        //tts.setPitch(1.0f);

        if (result == TextToSpeech.LANG_MISSING_DATA
                || result == TextToSpeech.LANG_NOT_SUPPORTED) {
            Log.e("TTS", "This Language is not supported");
        } else {
            speakOut(0);
        }

    } else {
        Intent installIntent = new Intent();
        installIntent.setAction(
            TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
        startActivity(installIntent);
    }
}
private void speakOut(int position) {
    tts.speak("Some text goes here", TextToSpeech.QUEUE_FLUSH, null);
}

Note: I tried setting value as 0.5f,0.8f etc., in both setPitch and setSpeechRate but still all the voice is not really clear as in GoogleTranslate App.

Your code looks fine. All tts libraries are shared across the system. Samsung comes with its own tts library. Rest of phones use Pico TTS. The great thing is that your app is independent from the library and you can download as many TTS libs as you want so that when you request the TTS intent the user will be prompt a pop-up to select which of their TTS synth they want for your app.

For me Pico TTS was working fine. Velocity / speech rate was normal, I just put the tone (pitch) a bit up to de-robotize the feeling a bit.

tts.setPitch(1.1f);

Try with Pico TTS and answer back.
