1) Start a voice recognition intent

2) Handle the returned data in onActivityResult() to decide which activity to start

1. Start a voice recognition intent

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Choose Activity");
startActivityForResult(intent, REQUEST_SPEECH);

2. Handle the returned data

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
        if (requestCode == REQUEST_SPEECH){
            if (resultCode == RESULT_OK){
                ArrayList<String> matches = data
                    .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

                if (matches.size() == 0) {
                    // didn't hear anything
                } else {
                    String mostLikelyThingHeard = matches.get(0);
                    // toUpperCase() used to make string comparison equal
                    if(mostLikelyThingHeard.toUpperCase().equals("ADVANCES")){
                        startActivity(new Intent(this, Advances.class));
                    } else if() {
                    }
                }
            }
        }

        super.onActivityResult(requestCode, resultCode, data);
    }
