How can I use speech recognition without the annoying dialog in android phones

Question

Is this possible without modify the android APIs? I've found a article about this. There's one a comment that I should do modifications to the android APIs. But it didn't say how to do the modification. Can anybody give me some suggestions on how to do that? Thanks!

I've found this article; SpeechRecognizer His needs is almost the same as mine. It is a good reference for me!

I've totally got this problem solved.
I googled a usable sample code from this China website Here's my source code

package voice.recognition.test;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.widget.Button;
import android.widget.TextView;
import java.util.ArrayList;
import android.util.Log;



public class voiceRecognitionTest extends Activity implements OnClickListener 
{

   private TextView mText;
   private SpeechRecognizer sr;
   private static final String TAG = "MyStt3Activity";
   @Override
   public void onCreate(Bundle savedInstanceState) 
   {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            Button speakButton = (Button) findViewById(R.id.btn_speak);     
            mText = (TextView) findViewById(R.id.textView1);     
            speakButton.setOnClickListener(this);
            sr = SpeechRecognizer.createSpeechRecognizer(this);       
            sr.setRecognitionListener(new listener());        
   }

   class listener implements RecognitionListener          
   {
            public void onReadyForSpeech(Bundle params)
            {
                     Log.d(TAG, "onReadyForSpeech");
            }
            public void onBeginningOfSpeech()
            {
                     Log.d(TAG, "onBeginningOfSpeech");
            }
            public void onRmsChanged(float rmsdB)
            {
                     Log.d(TAG, "onRmsChanged");
            }
            public void onBufferReceived(byte[] buffer)
            {
                     Log.d(TAG, "onBufferReceived");
            }
            public void onEndOfSpeech()
            {
                     Log.d(TAG, "onEndofSpeech");
            }
            public void onError(int error)
            {
                     Log.d(TAG,  "error " +  error);
                     mText.setText("error " + error);
            }
            public void onResults(Bundle results)                   
            {
                     String str = new String();
                     Log.d(TAG, "onResults " + results);
                     ArrayList data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
                     for (int i = 0; i < data.size(); i++)
                     {
                               Log.d(TAG, "result " + data.get(i));
                               str += data.get(i);
                     }
                     mText.setText("results: "+String.valueOf(data.size()));        
            }
            public void onPartialResults(Bundle partialResults)
            {
                     Log.d(TAG, "onPartialResults");
            }
            public void onEvent(int eventType, Bundle params)
            {
                     Log.d(TAG, "onEvent " + eventType);
            }
   }
   public void onClick(View v) {
            if (v.getId() == R.id.btn_speak) 
            {
                Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);        
                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
                intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,"voice.recognition.test");

                intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,5); 
                     sr.startListening(intent);
                     Log.i("111111","11111111");
            }
   }
}

Be sure to delete the annoying Logs after debugging!

It's definitely possible to do, as I've seen other apps do it (Voice infinity) but as for how, I haven't a clue. I'd imagine you could start by downloading the android source and checking in the api where the voice is, and then experiment extending... – Canberra

as noted by Femi, make sure to have <uses-permission android:name="android.permission.RECORD_AUDIO" /> in your AndroidManifest.xml file otherwise SpeechRecognizer will not pick up any audio – Barbate

Answer 1

Use the SpeechRecognizer interface. Your app needs to have the RECORD_AUDIO permission, and you can then create a SpeechRecognizer, give it a RecognitionListener and then call its startListening method. You will get callbacks to the listener when the speech recognizer is ready to begin listening for speech and as it receives speech and converts it to text.

also don't forget to destroy SpeechRecognier in OnDestroy() method as noted here: https://mcmap.net/q/181900/-mainactivity-has-leaked-serviceconnection-android-speech-speechrecognizer-connection-414ee400-that-was-originally-bound-here to not get has leaked ServiceConnection android.speech.SpeechRecognizer$Connection@414f0e40 that was originally bound here error – Barbate

Can you please show me an example? Also, can I use this while the screen is off? – Redouble

SpeechRecognizer is a class, not an interface. – Yeta

Answer 2

GAST has a handy abstract class you can use to use the SpeechRecognizer class with very little new code. There is also an example of running the SpeechRecognizer as a background service using this and this

Would you mind guiding me on how to implement them into the MainActivity? What does this mean "* Use {@link Intent}s to start and stop it?" Thanks a lot – Sholom

Thanks for posting this! I found it helpful to define the onclick listener in oncreate:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mText = (TextView) findViewById(R.id.textView1);     
    MyRecognitionListener listener = new MyRecognitionListener();
    sr = SpeechRecognizer.createSpeechRecognizer(this);       
    sr.setRecognitionListener(listener);

    findViewById(R.id.button1).setOnClickListener( new View.OnClickListener() {
        @Override
        public void onClick(View v) 
        {
                Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);    
                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
                intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,1); 
                intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,"voice.recognition.test");
                sr.startListening(intent);
        }
    });     
}

I end up making Github project to convert Text to speech and speech to text without annoying dialog,

https://github.com/hiteshsahu/Android-TTS-STT/tree/master/app/src/main/java/com/hiteshsahu/stt_tts/translation_engine

 //SPEECH TO TEXT DEMO
    speechToText.setOnClickListener({ view ->

        Snackbar.make(view, "Speak now, App is listening", Snackbar.LENGTH_LONG)
                .setAction("Action", null).show()

        TranslatorFactory
                .instance
                .with(TranslatorFactory.TRANSLATORS.SPEECH_TO_TEXT,
                        object : ConversionCallback {
                            override fun onSuccess(result: String) {
                                sttOutput.text = result
                            }

                            override fun onCompletion() {
                            }

                            override fun onErrorOccurred(errorMessage: String) {
                                erroConsole.text = "Speech2Text Error: $errorMessage"
                            }

                        }).initialize("Speak Now !!", this@HomeActivity)

    })


    //TEXT TO SPEECH DEMO
    textToSpeech.setOnClickListener({ view ->

        val stringToSpeak :String = ttsInput.text.toString()

        if (null!=stringToSpeak &&  stringToSpeak.isNotEmpty()) {

            TranslatorFactory
                    .instance
                    .with(TranslatorFactory.TRANSLATORS.TEXT_TO_SPEECH,
                            object : ConversionCallback {
                                override fun onSuccess(result: String) {
                                }

                                override fun onCompletion() {
                                }

                                override fun onErrorOccurred(errorMessage: String) {
                                    erroConsole.text = "Text2Speech Error: $errorMessage"
                                }

                            })
                    .initialize(stringToSpeak, this)

        } else {
            ttsInput.setText("Invalid input")
            Snackbar.make(view, "Please enter some text to speak", Snackbar.LENGTH_LONG).show()
        }

    })
