Thanks for question,

You can do for example as below to register to recognizing or recognized events in your Android project

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private void RecognizingHandler(SpeechRecognitionEventArgs e) {
        final String s = e.getResult().getText();
        Log.i(logTag, "Intermediate result received: " + s);
    }

    private void RecognizedHandler(SpeechRecognitionEventArgs e) {
        final String s = e.getResult().getText();
        Log.i(logTag, "Final result received: " + s);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ActivityCompat.requestPermissions(MainActivity.this, new String[]{RECORD_AUDIO, INTERNET}, requestCode);

        try {
            speechRecognizerConfig = SpeechConfig.fromSubscription("your key", "your region");
            recognizer = new SpeechRecognizer(speechRecognizerConfig);
            recognizer.recognizing.addEventListener((o,speechRecognitionResultEventArgs) -> {
                RecognizingHandler(speechRecognitionResultEventArgs);
            });
            recognizer.recognized.addEventListener((o, speechRecognitionResultEventArgs) -> {
                RecognizedHandler(speechRecognitionResultEventArgs);
            });
        }
        catch (Exception ex) {
            System.out.println(ex.getMessage());
            displayException(ex);
            return;
        }
    }
}
