Answer
Although Hank Azaria is one of the main voice actors on The Simpsons, he does not voice Homer Simpson. Homer is voiced by Dan Castellaneta, who has also voiced characters such as Krusty the Clown and Groundskeeper Willie. Azaria voices a variety of other characters on the show, including Moe Szyslak, Apu Nahasapeemapetilon, and Chief Wiggum.
