EG Daily wasn’t Babe the talking pig- it was Christine Cavanaugh.
But she did play Dottie in Pee Wee’s Big Adventure!
Don’t forget Cree Summer, who starred as Freddie in A Different World.
She got her start as Penny from Inspector Gadget. She also voiced Elmyra in Tiny Toons, a variety of different Nickalodeon characters (like Susie Carmichael from Rugrats), and does the voices for the M&M commercials.
When Cree Summers first showed up on A Different World, her voice kept bothering the hell out of me. I couldn’t figure out* why. * So familiar. Yet so annoying. It was only two years ago I finally figured it out.
We loved Inspector Gadget, but me and my brother couldn’t stand Penny.
But EG did take over the vocal chops (pun intended) for the porker in the sequel, Babe: Pig in the City.
This is who I came in here to mention. I first heard her on her debut album, which I listened to nearly non-stop the summer it came out. I then forgot about her, only to find out a few years later that she’d voiced a tonne of characters I knew.
David McCullough, known much more for his voice, but has done some acting.
Well, Casey Kasem was about equally famous as the American Top 40 disc jockey and as the voice of hundreds of cartoon characters (motst notably Shaggy, in “Scooby Doo”).
Norm MacDonald of SNL fame is the voice of Death on Family Guy as well as the voice of Lucky-- the dog on Dr. Doolittle.
The voice of Death is (now) Adam Corolla. Norm only did it once.
I forgot about William Daniels, voice of K.I.T.T. in Knight Rider visible in St. Elsewhere, Boy Meets World, etc.
Did you know her sang the Mr. Grinch song in the original Chuck Jones cartoon? “You’re as cuddly as a cactus, you’re as charming as an eel, Mister GriiiiiiiiINCH!”
Let’s see…
Tim Matheson was the voice of the original Jonny Quest.
Ted Knight was the narrator on the original Superfriends. “Laterrrrr…at…The Hall of Justice!”
A couple more ex-Seinfeld actors are all over the airwaves as voice actors.
John O’Hurley (J. Peterman) can be heard in Duck Dodgers, Kim Possible, Tarzan, Buzz Lightyear, et. al.
Wayne Knight (Newman) is in Xaolin Showdown, and I know I’ve heard his voice other places from time to time.
What, no mention of Gary Owens?
The staff announcer on Laugh-In has done a TON of voice work (over 3,000 cartoon shows, according to the IMDB), from Roger Ramjet through Scooby-Doo (Blue Falcon} to Ren & Stimpy (Powdered Toast Man).
He’s also appeared as himself either as host, announcer, or commentator, on a number of TV shows and movies, most recently on The Aristocrats.
Had a chance to share a drink with him a 25 yeara ago at a National Association of Broadcasters convention in Las Vegas. Another small-town DJ and I had about 20 mintues with him, and he patiently answered all our questions, including what Paul Frees was really like.
A true gentleman, and a class act. 
Tim Curry has done a considerable amount of voice work as well as being quite famous for his live action work.
John Ratzenberger (a flunky in one of the Star Wars movies; also played that guy in Cheers) has done some voice work, particularly, every movie Pixar has made.
And don’t forget Carl Lumbly, another superhero voice king, who I recognize from Cagney & Lacey.
And Michael Dorn, who does a ton of voice work.
Fact: Casey Kasem started doing the voice of Shaggy in 1969 (and he’s still doing it.) American Top 40 debuted a year later. So Casey has actually been doing the voice of Shaggy longer than he has been a disc jockey. Zoinks!
Would recognizing Takehito Koyasu’s teeth count?
(for the uninformed, he is a very popular Japanese voice actor known for his beautiful voice, but also for his horrible, hideous teeth)

I’d recognize Thurl Ravenscroft’s voice in a second, but I don’t think I could pick out his face (even though I think I’ve seen it).
