Voice/Speech Recognition on Android

Voice/Speech Recognition on Android

in Android Processing • 2 years ago

I am working to get the speech recognition capable on the android devices to work with processing. I am having difficulty getting the results from the speech recognition engine though. I am capable of calling an intent to launch the recognition app:

Intent intent = new Intent("android.speech.action.RECOGNIZE_SPEECH");
startActivityForResult(intent, 0);

What is not working is the results portion:

void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1234 && resultCode == RESULT_OK) {
ArrayList<String> matches = data.getStringArrayListExtra("RecognizeSpeech.EXTRA_RESULTS");
}
super.onActivityResult(requestCode, resultCode, data);
}

I am unable to get the data out of the ArrayList. I am using the example code provided here for reference: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html

Does anyone have any ideas about how to get this to work? Thanks

The problem might be that you're setting the requestCode when starting the activity to 0, and then when you're reading the requestCode from the result you expect 1234.

Try starting the activity with:

startActivityForResult( intent, 1234 );

I must have forgotten to change that from the example, thanks for pointing it out. However, I can not get it to work still. I do not think the onActivityResult is being called. The only other problem i have not figured out is how to get the first string out of the array. I have tried the .get() function but have not been auccessful. The app also seems to force quit when I use it.
