I am creating an app for the blind, so I need to read the input of a button

I am creating an app for the blind. I need to read the input from a button, but before reading it, I want to play an audio about the button's content. So when my finger is over the button, I need to play the audio, that is, the word that is given to the button.

How can i do this?

        @Override
       protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);

         getSupportActionBar().hide();// this is the code for the hide applicatoin name
          getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
    //to hide the notification bar

        Button speakButton = (Button) findViewById(R.id.bt1);
        speakButton.setOnKeyListener(this);
         tts = new TextToSpeech(this, this);
     }

You can add a touch listener, then check the event type to see if its an ACTION_DOWN or ACTION_UP event.



speakButton.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
       if (event.getAction() == android.view.MotionEvent.ACTION_DOWN) {
           //play sound
       } else if (event.getAction() == android.view.MotionEvent.ACTION_UP) {
          //do action
       }

       return true;
   }
});
