An ArrayList<String> of the recognition results when performing RecognizerIntent.ActionRecognizeSpeech. Generally this list should be ordered in descending order of speech recognizer confidence. (See RecognizerIntent.ExtraConfidenceScores). Returned in the results; not to be specified in the recognition request. Only present when Android.App.Activity.RESULT_OK is returned in an activity result. In a PendingIntent, the lack of this extra indicates failure.
