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

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.

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.
