UtterAsterisk with audio reference would be cool

[michaelsjackson]

Instead of kind of midi like notes. Is there already any such tool?
I am imagining following workflow from command line:
java -jar UtterAsterisk.jar --reference /path/to/reference/audio.wav

Then you try singing as close as possible and seeing your score.
Allowing mp3 reference would be even more useful, saving one more step.
