recognitionLevel: The level of recognition to prioritize. Set this level to RecognitionLevelFast to prioritize speed over accuracy, and to RecognitionLevelAccurate to prioritize accuracy at the expense of speed.
error: An error that contains information about failed language support, or nil if no error occurred.

Request revision is set automatically by OS version.
Returns an array of supported languages, listed as ISO language codes.

A language supported in one recognition level may not be available in another recognition level.
