speech to text api other language android

I develop android application that can recognize speech in Mandarin, then yield text. But i can't find how to do that. Can someone give me example code of speech recognition in other language(mandarin, france, etc) ?

public class MainActivity extends Activity {

private TextView txtSpeechInput;
private ImageButton btnSpeak;

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

txtSpeechInput = (TextView) findViewById(R.id.txtSpeechInput);
btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);

// hide the action bar
getActionBar().hide();

btnSpeak.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
listen();
}
});

}



private static int SR_CODE = 123;

/**
* Initializes the speech recognizer and starts listening to the user input
*/
private void listen() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
//Specify language
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.SIMPLIFIED_CHINESE);
// Specify language model
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
// Specify how many results to receive
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 5);
// Start listening
startActivityForResult(intent, SR_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == SR_CODE && resultCode == RESULT_OK) {
if (data != null) {
// Retrieves the best list SR result
ArrayList<String> nBestList = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
String bestResult = nBestList.get(0);
Toast.makeText(getApplicationContext(), bestResult,
Toast.LENGTH_LONG).show();
} else {
// Reports error in recognition error in log
Log.e("Log", "Recognition was not successful");
}
}

}



@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

Answer

You can set RecognizerIntent.EXTRA_LANGUAGE when you call the recognizer.

So an example in simplified chinese will be:

private static int SR_CODE = 123;


/**
     * Initializes the speech recognizer and starts listening to the user input
     */
    private void listen()  {
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        //Specify language
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.SIMPLIFIED_CHINESE)
        // Specify language model
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        // Specify how many results to receive
        intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 5);
        // Start listening
        startActivityForResult(intent, SR_CODE);
    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == SR_CODE && resultCode == RESULT_OK)  {
                if(data!=null) {
                //Retrieves the best list SR result
                ArrayList<String> nBestList = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
               String bestResult = nBestList.get(0);
               Toast.makeText(getApplicationContext(), bestResult, Toast.LENGTH_LONG).show;              
            }else {         
                //Reports error in recognition error in log
                Log.e(LOGTAG, "Recognition was not successful");
            }

    }
