Вы можете создать собственный распознаватель речи, который даст вам больше контроля над пользовательским интерфейсом.MainActivity открывает новый DialogFragment, в котором реализован RecognitionListener.
public class MainActivity extends AppCompatActivity implements VoiceRecognizerInterface {
Button button ;
TextView textView;
String string;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.button);
textView = findViewById(R.id.textView);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
FragmentManager fragmentManager = getSupportFragmentManager();
if (fragmentManager != null && fragmentManager.findFragmentByTag("dialogVoiceRecognizer") == null && !isFinishing()) {
VoiceRecognizerDialogFragment languageDialogFragment = new VoiceRecognizerDialogFragment(MainActivity.this,MainActivity.this);
languageDialogFragment.show(fragmentManager, "dialogVoiceRecognizer");
}
}
});
}
@Override
public void spokenText(String spokenText) {
textView.setText(spokenText);

Интерфейс для оповещения об основной активности после stt.
