How do I use Android SpeechRecognizer as a service?
android, service, voice-recognition
Solution
you can do this:
public class OpenMicService extends Service implements RecognitionListener{
private static final int VOICE_RECOGNITION_REQUEST_CODE = 1234;
private SpeechRecognizer speechRecognizer;
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public int onStartCommand(Intent intent,int flags,int startId) {
Toast.makeText(this,"start Service.",Toast.LENGTH_SHORT).show();
speechRecognizer = SpeechRecognizer.createSpeechRecognizer(getApplicationContext());
speechRecognizer.setRecognitionListener(this);
Intent voice = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
voice.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass()
.getPackage().getName());
voice.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
voice.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 10);
speechRecognizer.startListening(voice);
return START_REDELIVER_INTENT;
}
@Override
public void onDestroy() {
super.onDestroy();
}
@Override
public void onReadyForSpeech(Bundle bundle) {
}
@Override
public void onBeginningOfSpeech() {
}
@Override
public void onRmsChanged(float v) {
}
@Override
public void onBufferReceived(byte[] bytes) {
}
@Override
public void onEndOfSpeech() {
}
@Override
public void onError(int i) {
}
@Override
public void onResults(Bundle results) {
String wordStr = null;
String[] words = null;
String firstWord = null;
String secondWord = null;
ArrayList<String> matches = results
.getStringArrayList(speechRecognizer.RESULTS_RECOGNITION);
wordStr = matches.get(0);
words = wordStr.split(" ");
firstWord = words[0];
secondWord = words[1];
if (firstWord.equals("open")) {
PackageManager packageManager = getPackageManager();
List<PackageInfo> packs = packageManager
.getInstalledPackages(0);
int size = packs.size();
boolean uninstallApp = false;
boolean exceptFlg = false;
for (int v = 0; v < size; v++) {
PackageInfo p = packs.get(v);
String tmpAppName = p.applicationInfo.loadLabel(
packageManager).toString();
String pname = p.packageName;
//URL urlAddress = urlAddress.toLowerCase();
tmpAppName = tmpAppName.toLowerCase();
if (tmpAppName.trim().toLowerCase().equals(secondWord.trim().toLowerCase())) {
PackageManager pm = this.getPackageManager();
Intent appStartIntent = pm.getLaunchIntentForPackage(pname);
if (null != appStartIntent) {
try {
this.startActivity(appStartIntent);
} catch (Exception e) {
}
}
}
}
} // end of open app code
}
@Override
public void onPartialResults(Bundle bundle) {
}
@Override
public void onEvent(int i,Bundle bundle) {
}
}
Problem
I am trying to run Android voice recognition as a service. I can verify that the onCreate() and onStart() methods of the service are called, but no callbacks to the speech recognition methods are called, despite the fact that I have set up the SpeechRecognizer object correctly. The speech recognition seems to work when it is done in an activity instead of a service. How do I make it work as a service? Is this a manifest issue? ``` package net.viralpatel.android.speechtotextdemo; import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; import java.util.ArrayList; import android.app.Service; import android.content.Intent; import android.os.Bundle; import android.os.IBinder; import android.speech.RecognitionListener; import android.speech.RecognizerIntent; import android.speech.SpeechRecognizer; import android.util.Log; import android.widget.Toast; public class MyService extends Service implements RecognitionListener { private SpeechRecognizer speechRecognizer; @Override public IBinder onBind(Intent arg0) { return null; } @Override public void onCreate() { Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show(); Log.d("tag", "onCreate"); speechRecognizer = SpeechRecognizer.createSpeechRecognizer(getApplicationContext()); speechRecognizer.setRecognitionListener(this); Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH); speechRecognizer.startListening(intent); } @Override public void onDestroy() { Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show(); Log.d("tag", "onDestroy"); } @Override public void onStart(Intent intent, int startid) { Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show(); Log.d("tag", "onStart"); } @Override public void onBeginningOfSpeech() { Log.d("Speech", "onBeginningOfSpeech"); } @Override public void onBufferReceived(byte[] buffer) { Log.d("Speech", "onBufferReceived"); } @Override public void onEndOfSpeech() { Log.d("Speech", "onEndOfSpeech"); } @Override public void onError(int error) { Log.d("Speech", "onError"); } @Override public void onEvent(int eventType, Bundle params) { Log.d("Speech", "onEvent"); } @Override public void onPartialResults(Bundle partialResults) { Log.d("Speech", "onPartialResults"); } @Override public void onReadyForSpeech(Bundle params) { Log.d("Speech", "onReadyForSpeech"); } @Override public void onResults(Bundle results) { Log.d("Speech", "onResults"); ArrayList strlist = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION); for (int i = 0; i < strlist.size();i++ ) { Log.d("Speech", "result=" + strlist.get(i)); } BufferedWriter out; try { out = new BufferedWriter(new FileWriter("mnt/sdcard/results.txt")); // out.write(processor.execute(strlist.get(0).toString())); out.write("hello world"); } catch (IOException e) { Log.e("Speech",e.toString()); } } @Override public void onRmsChanged(float rmsdB) { Log.d("Speech", "onRmsChanged"); } } ```
