Text To Speech in Dialog, weird behavior

The code opens a Dialog , in which a user entered EditText is converted to speech using TTS and the output is played. 

 final   EditText input = new EditText(this);
    input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_CLASS_TEXT);
    builder.setView(input);


    builder.setPositiveButton("SAVE", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

                File directory = new File(Environment.getExternalStorageDirectory()+"/myAppCache/");
            //if (!directory.exists()) {
                directory.mkdirs();
            //}


            HashMap<String, String> myHashRender = new HashMap();
            String toSpeak = input.getText().toString();
            t1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);

            String destFileName = Environment.getExternalStorageDirectory()+"/myAppCache/wakeUp.wav";

            myHashRender.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, toSpeak);
            t1.synthesizeToFile(toSpeak, myHashRender, destFileName);
            t1.stop();
            t1.shutdown();
        }
    });
    builder.setNegativeButton("Play", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            String toSpeak = input.getText().toString();
            t1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);



        }
    });

    builder.show();
}

And obviously there are two buttons in the Dialog, setPositiveButton and setnegativeButton , positive button saves the output as a .wav file , also plays the output. the negative button also plays the output. But t1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null); does not produce any output in the positive button. What is causing this? Anything to take care while using Dialogs?

It's nothing to do with Dialogs, the problem is you are telling it to stop!

The call to speak() is non-blocking. From the API:

The synthesis might not have finished (or even started!) at the time when this method returns.

Your code is:

START SPEAKING -> t1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);

                  String destFileName = Environment.getExternalStorageDirectory()+"/myAppCache/wakeUp.wav";

                  myHashRender.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, toSpeak);
                  t1.synthesizeToFile(toSpeak, myHashRender, destFileName);
STOP SPEAKING ->  t1.stop();

So after you tell it to start you do a few more things, then tell it to stop - most likely before any sound has even been produced.
