        final Context appContext = context.getApplicationContext();
        if (sTts == null) {
           sTts = new SoftReference<TextToSpeech>(new TextToSpeech(appContext,
                    new TextToSpeech.OnInitListener() {
                        @Override
                        public void onInit(int status) {
                            if (status == TextToSpeech.SUCCESS) {
                                speak(appContext, s);
                            } else {
                                loadText2SpeechData(appContext);
                            }
                        }
                    }));
        } else {
           speak(appContext, s);
        }
    }


    private static void speak(Context context, String s) {
        if (sTts != null) {
            switch (sTts.get().setLanguage(Locale.getDefault())) {
              case TextToSpeech.LANG_COUNTRY_AVAILABLE:
              case TextToSpeech.LANG_COUNTRY_VAR_AVAILABLE:
              case TextToSpeech.LANG_AVAILABLE: {
                  speakWhenOK(context, s);
                  break;
              }
              case TextToSpeech.LANG_MISSING_DATA: {
                  loadText2SpeechData(context);
                  break;
              }
              case TextToSpeech.LANG_NOT_SUPPORTED:
            }
        }
    }

    @SuppressLint("NewApi")
    private static void speakWhenOK(Context context, String s){ 
        final Context myContext = context;  

        SharedPreferences prefs =PreferenceManager.getDefaultSharedPreferences(context);


        HashMap<String, String> ttsParameters = new HashMap<String, String>();

        ttsParameters.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,String.valueOf(Math.random()) );   

        sTts.get().speak(s, TextToSpeech.QUEUE_ADD, ttsParameters);
    }   
}

give an id to your rootview, and then (eg. ROOT) then initialize it, and then

try this :

RootView.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View arg0, MotionEvent arg1) {
                // TODO Auto-generated method stub
            //
            //  run your stop(), for speech here
            }
        });
