android, RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE does not work in speech to text

Suddenly, my speech to text app which has the following statement does not work. It remains at English(United Kingdom). The language on the dialog box does not changed.

I open source the complete codes.😉

    intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    Long timeToWait = 20000L;
    intent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);

    intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS, 3000);
    intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS, 3000);
    intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 3000);

        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
 
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, mylanguage);
    intent.putExtra(RecognizerIntent.EXTRA_ONLY_RETURN_LANGUAGE_PREFERENCE,
            mylanguage);
 

    startActivityForResult(intent, RESULT_SPEECH);

Is it possible there is a bug from Android or miui Global 14.0.1? Is there a fix?

It is probably a bug in the recent version of the system app “Speech Recognition & Synthesis”. The language learning app I am developing is also not working properly.

Can you “uninstall” Speech Recognition & Synthesis from Google Play and revert to the old version so it will work again?
