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

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);

        }

    }

}

For the complete code check out this github project:
https://github.com/gast-lib

there is no solution but a hackaround...

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

check here the complete story.

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");

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.

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());

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);
