• Create a Speech2TextIntent and pass necessary flags to it when you wish to trigger Speech recognition. The allowed flags are Speech2TextIntent.LANGUAGE.

• Values of Speech2TextIntent.LANGUAGE flag can be

  • Speech2TextIntent.LANGUAGE_ENGLISH
  • Speech2TextIntent.LANGUAGE_HINDI
  • Speech2TextIntent.LANGUAGE_TELUGU
  • Speech2TextIntent.LANGUAGE_KANNADA
  • Speech2TextIntent.LANGUAGE_PUNJABI

  • Speech2TextIntent.LANGUAGE_GUJARATI
  • Speech2TextIntent.LANGUAGE_MARATHI

Speech2TextIntent.LANGUAGE flag is optional. The default value is Speech2TextIntent.LANGUAGE_ENGLISH.

int REQUEST_CODE = 1;
Intent i = new Intent(getActivity(), Speech2TextIntent.class);
// set LANGUAGE. Following line is optional
i.putExtra(Speech2TextIntent.LANGUAGE, Speech2TextIntent.LANGUAGE_ENGLISH);
startActivityForResult(i, REQUEST_CODE);

• Once the speech input is done, you need to read the results from onActivityResult and take appropriate actions. The result can be read from data.getStringArrayExtra("resultList").

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == 1) {
            if(resultCode == Activity.RESULT_OK){
                String[] results = data.getStringArrayExtra("resultList"); 
            } } }
