SpeechRecognizer causes ANR... I need help with Android speech API.
- by Dondo Chaka
I'm trying to use Android's speech recognition package to record user speech and translate it to text. Unfortunately, when I attempt initiate listening, I get an ANR error that doesn't point to anything specific.
As the SpeechRecognizer API indicates, a RuntimeException is thrown if you attempt to call it from the main thread. This would make me wonder if the processing was just too demanding... but I know that other applications use the Android API for this purpose and it is typically pretty snappy.
java.lang.RuntimeException: SpeechRecognizer should be used only from the application's main thread
Here is a (trimmed) sample of the code I'm trying to call from my service. Is this the proper approach?
Thanks for taking the time to help. This has been a hurdle I haven't been able to get over yet.
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,
"com.domain.app");
SpeechRecognizer recognizer = SpeechRecognizer
.createSpeechRecognizer(this.getApplicationContext());
RecognitionListener listener = new RecognitionListener() {
@Override
public void onResults(Bundle results) {
ArrayList<String> voiceResults = results
.getStringArrayList(RecognizerIntent.EXTRA_RESULTS);
if (voiceResults == null) {
Log.e(getString(R.string.log_label), "No voice results");
} else {
Log.d(getString(R.string.log_label), "Printing matches: ");
for (String match : voiceResults) {
Log.d(getString(R.string.log_label), match);
}
}
}
@Override
public void onReadyForSpeech(Bundle params) {
Log.d(getString(R.string.log_label), "Ready for speech");
}
@Override
public void onError(int error) {
Log.d(getString(R.string.log_label),
"Error listening for speech: " + error);
}
@Override
public void onBeginningOfSpeech() {
Log.d(getString(R.string.log_label), "Speech starting");
}
};
recognizer.setRecognitionListener(listener);
recognizer.startListening(intent);
