I think this is a brilliant idea and is no doubt useful for discovering variations in pronunciation as well. The first thing I tested it with was "mischievous" which notoriously has a correct - "MIS-chu-vus" - as well as an "incorrect" but very common pronunciation - "mis-CHEE-vee-us" - both of which are represented.
