Android : Android TTS only speaking english

i have a strange issue with android tts.I have used locale.getDefault for getting default locale for tts set language.If i changed my phone locale to other languages tts not speaking anything.please help me out.

@Override
        public void onInit(int status) 
        {
            if(status == TextToSpeech.SUCCESS)
            {
                try
                {
                    int result = tts.setLanguage(Locale.getDefault());

                    Log.e("LANGUAGE", "Result : " + result  + " " + Locale.getDefault().getLanguage());

                    if(result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED)
                    {
                        tts.setLanguage(Locale.ENGLISH);
                    }

                } catch (Exception e)
                {
                    e.printStackTrace();
                }                   
            }
        }

btn_Check.setOnClickListener(new OnClickListener()
    {           
        @Override
        public void onClick(View v) 
        {

            String text =et_Check.getText().toString().trim();
            if(!text.equals(""))
                Log.e("Strnig", text);
                tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);

        }
    });
