How to hide toast message “Your audio will be sent to google to provide speech recognition service.” in Android?

问题

I am using google speech recognizer for integrating voice services in Android but while pressing on mic button this annoying toast message is showing. Please suggest me a way to hide this toast message.

This is my java code

public class FormActivity extends AppCompatActivity {

    AppCompatEditText mFeedbackView; 
    ImageView mFeedbackVoiceView;
    private final int REQ_CODE_SPEECH_INPUT_FEEDBACK = 100;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_form);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        mVisitFeedbackView = findViewById(R.id.feedback);
        mFeedbackVoiceView = findViewById(R.id.feedback_voice);

        mFeedbackVoiceView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                promptSpeechInputFeedback();
            }
        });
    }
    private void promptSpeechInputFeedback() {
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
        intent.putExtra(RecognizerIntent.EXTRA_PROMPT, getString(R.string.speech_prompt));
        try {
            startActivityForResult(intent, REQ_CODE_SPEECH_INPUT_FEEDBACK);
        } catch (ActivityNotFoundException a) {
            Toast.makeText(getApplicationContext(), getString(R.string.speech_not_supported), Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch (requestCode) {
            case REQ_CODE_SPEECH_INPUT_FEEDBACK: {
                if (resultCode == RESULT_OK && null != data) {
                    ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS); 
                    mFeedbackView.setText(result.get(0));
                }
                break;
            }  
        }
    }
}

This question is duplicate of How to hide toast“ Your audio will be sent to google to provide speech recognition service.” in Speech Recognizer? but there are no solution for this.

Any help will be appreciated.

回答1:

Based on android regulations you cannot hide system toast messages as you don't have the accesses to the system View,

only in jailbrake android where you have access to the terminal you can try to do that.

You can make a custom speech recogniser which will give you more control over the UI. MainActivity opens a new DialogFragment which implements 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);
    }
}

An interface to signal the main activity after stt.

public interface VoiceRecognizerInterface {
    void spokenText(String spokenText);
}

The custom SpeechToText Dialog.

public class VoiceRecognizerDialogFragment extends DialogFragment implements RecognitionListener{

    ImageView micImage;
    TextView stateTV;
    TextView displayTV;

    private SpeechRecognizer mSpeechRecognizer;
    private Intent mSpeechRecognizerIntent;
    private Context context;
    VoiceRecognizerInterface signal;

    @SuppressLint("ValidFragment")
    public VoiceRecognizerDialogFragment(Context context, VoiceRecognizerInterface signal) {
        this.context = context;
        this.signal = signal;
    }

    public VoiceRecognizerDialogFragment(){

    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.voice_recognizer_custom_layout ,container, false );

        //Mic tap to listen again
        micImage = view.findViewById(R.id.micImageView);
        //Displays Listening.. when recognizer is listening
        stateTV = view.findViewById(R.id.stateTV);
        //Displays message if error
        displayTV = view.findViewById(R.id.displayTV);

        mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(context);
        mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
        //Customize language by passing language code
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE,"en");
        //To receive partial results on the callback
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS,true);
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                context.getPackageName());
        mSpeechRecognizer.setRecognitionListener(this);
        mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
        micImage.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startListening();
            }
        });
        return view;

    }

    public void startListening(){
        mSpeechRecognizer.setRecognitionListener(this);
        mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
        changeUIStateToListening();
    }


    @Override
    public void onDestroy() {
        super.onDestroy();
        if (mSpeechRecognizer != null) {
            mSpeechRecognizer.destroy();
        }
    }

    @Override
    public void onBeginningOfSpeech()
    {

    @Override
    public void onBufferReceived(byte[] buffer)
    {

    }

    @Override

    {

    @Override
    public void onError(int error)

        if(error == 7){

    @Override

    {
        ArrayList<String> matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
        if(matches == null){
            return;
        }
        int i =0;
        String first ="";
        for(String s : matches){
            if(i==0){
                first = s;
            }
            i++;
        }
        // sending text to MainActivity using Interface
        signal.spokenText(first);
        this.dismiss();
    }

    @Override
    public void onRmsChanged(float rmsdB)
    {
    }

    public void changeUIStateToListening(){
        displayTV.setText("Tell us what you need");
        stateTV.setText("Listening...");
