Android SpeechRecognizer “confidence” values are confusing

Question

I\'m using the SpeechRecognizer via Intent:

Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL         


        

Answer 1

I haven't work with speech reorganization. But still, as you said you are getting float array value as 0.0, this implies float array is null . can you please check is the float[] is returning null or else.

ArrayList results = data
            .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

float[] confidence = data.getFloatArrayExtra(
            RecognizerIntent.EXTRA_CONFIDENCE_SCORES);
if (confidence == null)
{
 for (int i = 0; i < results.size(); i++)
  {
   Log.d(TAG, i + ": " + results.get(i));
  }
}
else
{
   for (int i = 0; i < results.size(); i++)

   {
     Log.d(TAG, i + ": " + heard.get(i) + " confidence : "  + confidence[i]);
  }
}
