My text to speech doesn't want to talk back to me

Question

I am still having problems with my TextToSpeech android, I entered the button twice once for the implemented Speech like exlipse asked me too and one for the implemented OnClickListener, Even if I take out the bottom action for the button it doesn't want to play, Why? idk it just doesn't want to say what is in my EditText Field I have no clue why it doesn't want to and I have asked around many times but I haven't goten an answer that worked.

Did you try speaking the text with just one method call? Like this

mTts.speak(aString, TextToSpeech.QUEUE_ADD, null);

It works fine for me. The initialization I use is the same as yours. The only remaining difference is this (which should not be necessary to get the TTS to work!):

        this.speaker.setSpeechRate(0.9f);
        this.speaker.setPitch(0.9f);
