I want to convert speech to text in my app..
For this i am using recognitionListener interface
Everything works fine but how to get the text updated and shown even while speaking( like in google now voice search)
I have set the RecognizerIntent.EXTRA_PARTIAL_RESULTS, to true
And also used the onPartialResults(Bundle arg() method of the recognitionListener interface to set text
By the whole text is getting displayed at once after speech recognition is complete
But i want the realtime text to be displayed as the user speaks
my activity
public class MainActivity extends Activity implements RecognitionListener

HOW TO MAKE THIS HAPPEN
You can't achieve a realtime recognition with google API. In the best case you can achieve the same result than google when you are using OK Google or for example Recognition in Whatsup for write Text word by word adding to your intent:
recognizerIntent.putExtra("android.speech.extra.DICTATION_MODE", true);
The Speechrecognizer take his time to process all the info and split it as info to be able to use it in your app. you can check the next post to see if it help you optimizing your app: Make SpeechRecognizer Faster
Hope that it will help you !

I've been working on this code for weeks with no progress at all, even though it seems like such an easy fix!! Basically I am using TextToSpeech with SpeechRecognizer in order to have the app ask me a question and then listen for my answer. Here's my code... I'm thinking its a thread problem or something.
Basically when I hold down the button, SPeechRecognizer starts listening until i take away finger... this works fine.. but I programmatically want the SpeechRecognizer to start up again after Utterance is Completed or simulate a button press to get it to work but neither works...

According to the UtteranceProgressListener docs, "The callbacks specified in this method can be called from multiple threads."
To verify this, you can add
boolean wasCalledFromBackgroundThread = (Thread.currentThread().getId() != 1);
Log.i("XXX", "was onDone() called on a background thread? : " + wasCalledFromBackgroundThread);
to the onDone() method body.
In my experience, they are called on background threads more often than not.
So, inside your onDone() method body, I would suggest surrounding the UI manipulation with runOnUiThread() like so:
#Override
public void onDone(String utteranceId) {
runOnUiThread(new Runnable() {
#Override
public void run() {
// possible method one:
SimulateButton.performClick();
// possible method two:
//mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
}
});
}
I've implemented a SpeechRecognizer, and it's working perfectly on Android 6, but its not working on android 7.0, I don't know why.
If I try to use the recognizer on startActivityforResult(), it work's perfectly, but if I use createListener method, nothing happens, even I tried to output all results.
Here is my code :
class listener implements RecognitionListener
{
String TAG = "AFFICHAGE";
public void onReadyForSpeech(Bundle params)
{
Toast.makeText(MainActivity.this,"READY TO LISTEN", Toast.LENGTH_LONG).show();
}
public void onBeginningOfSpeech()
{
}
public void onRmsChanged(float rmsdB)
{
}
public void onBufferReceived(byte[] buffer)
{
Log.d(TAG, "onBufferReceived");
}
public void onEndOfSpeech()
{
Log.d(TAG, "onEndofSpeech");
}
public void onError(int error)
{
switch (error){
case SpeechRecognizer.ERROR_AUDIO:
Toast.makeText(MainActivity.this, "ERROR AUDIO",Toast.LENGTH_LONG).show();
break;
case SpeechRecognizer.ERROR_CLIENT:
Toast.makeText(MainActivity.this, "ERROR CLIENT",Toast.LENGTH_LONG).show();
break;
case SpeechRecognizer.ERROR_INSUFFICIENT_PERMISSIONS:
Toast.makeText(MainActivity.this, "ERROR PERMISSION",Toast.LENGTH_LONG).show();
break;
case SpeechRecognizer.ERROR_NETWORK:
Toast.makeText(MainActivity.this, "ERROR INTERNET",Toast.LENGTH_LONG).show();
break;
case SpeechRecognizer.ERROR_NETWORK_TIMEOUT:
Toast.makeText(MainActivity.this, "ERROR TIMEOUT",Toast.LENGTH_LONG).show();
break;
case SpeechRecognizer.ERROR_NO_MATCH:
Toast.makeText(MainActivity.this, "ERROR NO MATCH",Toast.LENGTH_LONG).show();
break;
case SpeechRecognizer.ERROR_RECOGNIZER_BUSY:
Toast.makeText(MainActivity.this, "ERROR BUSY",Toast.LENGTH_LONG).show();
break;
case SpeechRecognizer.ERROR_SERVER:
Toast.makeText(MainActivity.this, "ERROR SERVER",Toast.LENGTH_LONG).show();
break;
case SpeechRecognizer.ERROR_SPEECH_TIMEOUT:
Toast.makeText(MainActivity.this, "ERROR TIMEOUT",Toast.LENGTH_LONG).show();
break;
default:
break;
}
}
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);
}
txtSpeechInput.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);
}
}
and here is where I call it :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtSpeechInput = (TextView) findViewById(R.id.txtSpeechInput);
btn = (Button) findViewById(R.id.button);
sr = SpeechRecognizer.createSpeechRecognizer(this);
sr.setRecognitionListener(new listener());
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
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");
}
});
}
Thank for answer.
I've found a solution to make it work on initializiting the google librairie like this : SpeechRecognizer.createSpeechRecognizer(getApplication(), ComponentName.unflattenFromString("com.google.android.googlequicksearchbox/com.google.android.voicesearch.serviceapi.GoogleRecognitionService"));
And it's work, so I don't now if it's a good solution or not.
I got this error when I pressed the Home button in Android Emulator.

call initSpeech inside the onCheckedChange().Otherwise sometime the speechReconginzer object may be destroyed.
This may help you
Try to destroy the speech object onError() endOfSpeech() and onResults() if Reconginzer Busy Error occur
I am writing an application, which has a WebView, that is handling a voice call via WebRTC. Microphone is working OK as I have granted permission to WebView.
webView.setWebChromeClient(new WebChromeClient() {
#Override
public void onPermissionRequest(final PermissionRequest request) {
request.grant(request.getResources());
}
Later I decided to add SpeechRecognizer so I can recognize what I am saying during the WebRTC call. I tried to make speech recognition work in the same activity, later I did it in a separate service, but unfortunally, it doesn't allow to work in a simultaneous way. Microphone gets occupied by WebView, and SpeechRecognizer doesn't get any sound (RMS is constantly -2.12). Or, if I try to run service before making call through WebView, the person I am calling to doesn't hear me at all (SpeechRecognizer occupies microphone and WebView doesn't get anything).
I hope to find any solution if it exists. I am not an iOS developer, but I've heard, that it's possible on iPhone, so it's a surprise, that is impossible on Android device.
