How to set the language in speech recognition on android?

I've been working on speech Recognition API in android and found out that the speech results vary allot when the language settings are changed , is there a way to set it programmatically ? or is there an intent to lunch the speech language settings screen ? or what else ? note: I tried to use this intent extra: 

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en-US");

but it was ineffective

this code is to set the language in speech recognization 

  String languagePref = "te-IN";//this is for telugu

     //kannada --->  "kn-IN"
     //tamil--->  "ta-IN".....

            Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
            intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                    RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
            intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, languagePref);

I tried to use

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());

but it did not work for me (did not take the system language). Helped here like this:

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault().toString());

I used this code:

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");

Hope you can run your app now.

there is no solution but a hackaround...

intent.putExtra("android.speech.extra.EXTRA_ADDITIONAL_LANGUAGES", new String[]{"en"});

check here the complete story.

As pargat says, this will do it:

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");

Also, your app can query for the list of supported languages by sending a RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS ordered broadcast like so:

    Intent detailsIntent =  new Intent(RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS);
    sendOrderedBroadcast(
            detailsIntent, null, new LanguageDetailsChecker(), null, Activity.RESULT_OK, null, null);

where LanguageDetailsChecker is something like this:

public class LanguageDetailsChecker extends BroadcastReceiver
{
    private List<String> supportedLanguages;

    private String languagePreference;

    @Override
    public void onReceive(Context context, Intent intent)
    {
        Bundle results = getResultExtras(true);
        if (results.containsKey(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE))
        {
            languagePreference =
                    results.getString(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE);
        }
        if (results.containsKey(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES))
        {
            supportedLanguages =
                    results.getStringArrayList(
                            RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES);
        }
    }
}

I finally got my app to restrict voice recognition results to a specified language input (handing it, e.g., "ja" for Japanese or "fr" for French) by adding all 3 of the following extras:

String languagePref = "de";//or, whatever iso code...
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, languagePref);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, languagePref); 
intent.putExtra(RecognizerIntent.EXTRA_ONLY_RETURN_LANGUAGE_PREFERENCE, languagePref);

Hope this helps someone.

This will work:

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en_US");

You have to use "en_US" instead of "en-US". The former is the right format of Java locale tag.

It is suggested that you use 

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.US.toString());

to avoid remembering such detail.

Have you tried this:

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");
