The most well known being Adam West.
Which reminds me, there was a (very) short-lived Car Talk animated series as well (Wikipedia says 10 episodes on PBS in the summer of 2008).
I’m not sure about that. Warner Brothers and other cartoon factories very often didn’t even try to get the original actor, often effectively “stealing” that actor’s schtick. Helen Kane, the “boop oop a doop Girl” , pretty famously tried to sue Fleischer studios, saying that Betty Boop stole her act.
Kenny Delmar’s “Senator Claghorn” was taken hook, line, and sinker by "Foghorn Leghorn’, practically down to the name.
Comedian Joe Penner is virtually forgotten today, except by vaudeville and radio fans, but he’s supposed to have been the inspiration for the Warner Brothers character Egghead, who arguably morphed into Elmer Fudd. Interestingly enough, though, Elmer’s speech pattern and his later appearance were due to voice actor Arthur Q. Bryan, who Warner Brothers DID hire.
Several Warner brothers cartoons used the appearance and in some cases even the voice and mannerisms of comedian Jerry Colonna, although he didn’t voice any of these. (particularly The Wacky Worm and Greetings, Bat!, the title of which is a riff on a Colonna catchphrase)
The first Tweety Bird cartoon feature, A Tale of Two Kitties, had two cats that are obvious caricatures of Abbott and Costello, who are even named Babbitt and Catstello.
The 1959 Warner Brothers Cartoon The Mouse that Jack Built features a cast resembling that of The Jack Benny Show, and voiced by them

Another parody done about the same time, The Honeymousers, however, didn’t use the voices of anyone from The Honeymooners
(The show may have been long gone by then, but they continued to do Honeymooners skits on Jackie Gleason’s weekly show)
Burt Reynolds voiced himself on Archer:
