Mumbly.
Try listening to him singing “Too Close For Paradise”…Yeep!
A couple of people have said that Sylvester Stallone is a mumbler; I don’t agree with them. I think sometimes his speech is relatively indistinct because, once again, for some reason he usually speaks out the side of his mouth. Oh, well. Dissenting opinions are partly the reason I opened this thread.
I do agree, however, that Barney Frank, Andy Devine, and Charlie Rangel have abysmal speaking voices. IMO Stallone can’t be on the same list as them.
Thanks anyways for going by making a Top 10 list (if not just a list of 10 people) like I suggested. Were either of them in a certain order?
Not really, they were just the first 10 people who immediately came to mind. I wasn’t sure whether to put Gilbert Gottfried on there or not, since I know that’s not his real voice. I could easily replace him with Brian Doyle-Murray, though…
I’ll supply three entrants for the best male voice:
Already mentioned Welshman Richard Burton, the voice on the War of the Worlds album
Englishman David Hemmings, the voice on the Journey to the Centre of the earth album
Irishman Richard Harris who was the best Dumbledore
Two that I like:
Rod Serling
John Corbett
Oh, and I forgot to mention that I also second Dick Vitale. Although to me, Gottfried’s screeching voice is pure hilarity to me and nothing other. It’s not even annoying IMO.
Three pages and not one mention of Patrick Wilson? THE Raoul from PotO?? Eau my gourd. I could listen to him sing all day long.
Wanna go for five pages, everyone? I’m kind of obsessed with this concept. :o 
According to Wikipedia, his face is partially paralyzed because of the misuse of forceps during his birth, causing his somewhat slurred speech.
We’ve noticed…
That explains it. Does misuse of forceps have something to do with the mouth or the jaws or whatnot?
just watched The Matrix again tonight.
Laurance Fishburne. Best.
Alison Krauss has the singing voice of an angel and the speaking voice which is well…regrettable.
Walter Cronkite did have a very good voice.
Robert MacNeil’s voice is just about the best one still living. Deep, deep voice; very soothing, mellifluous, trustworthy, and professional, with a bit of his old Canadian nasalness left in it; he still has those Nova Scotia err’s. 
Seth MacFarlane does indeed have a strong, alluring baritone voice.
Former Prime Minister of England Gordon Brown has a very calming bass-baritone voice.
In my World Cultures class, we watched The Last Emperor, which stars Peter O’Toole. His voice has deteriorated largely, but back then in 1987, it was marvelous.
Sahara Smith, a young and very obscure singer, has a speaking voice to match the orgasmic-ness of her singing voice.
Sutton Foster and Susan Egan’s voices (once again, speaking and singing) never fail to anger me with their inherent cuteness combined with sexiness.
Denyce Graves is another singer, an operatic mezzo-soprano whose speaking voice is a contralto. She is black, but she doesn’t have a trace of an accent. Nonetheless, you can tell she’s black just by listening to her. I don’t quite know how; there’s a darkness and authority that’s reminiscent of any African-American, with an accent or not.
Meryl Streep’s voice is sooooooo soothing.
Laura Nyro is yet another singer who died in 1997 at the age of 49. She did many genres. Her singing voice was flawless; unaffected by the raw emotion that you could still tell was there. In fact, this emotion might have only made her vocals more pristine, though it did the opposite with Bob Dylan, Lou Reed, etc. Nyro’s speaking voice is…how on earth do you say how magnificent it is. A deep, velvety, almost husky contralto. When she speaks, it sounds like she’s telling you a secret; like she trusts you more than anyone else.
Anne Bancroft’s speaking voice is seductive. 
Lauren Bacall has a beautiful voice in a very different way. It is indeed husky, yet very refined. Somehow it reminded me of when I was much younger. For some reason, it actually reminded me of watching the 1954 theater production of Peter Pan, which I used to watch all the time.
There is a boy at my school—a twelfth grader—who appears to be Arab (not that that matters; just giving you a visual). He has the squeakiest, whiniest, unsteadiest, most accidentally grating countertenor you may ever hear.
Clay Aiken, Walter Payton, and Robert F. Kennedy, Jr. do indeed have horrid speaking voices.
I don’t know if I like or dislike Harvey Fierstein’s voice. It’s a powerful resonant bass-baritone, but he sounds like a frog is stuck in his throat.
I don’t know if I mentioned this, but Larry Platt, the Pants-on-the-ground guy from…American Idol? I didn’t care, but he has one of the worst speaking voices I have heard.
People comment on George Lucas’s neck blubber, but not on his voice? He makes Casey Affleck sound like Lorne Greene.
I recently discovered that Shel Silverstein has one of the most horrid speaking voices possibly to ever have been heard.
Look for a TV Legends archive interview with Don Knotts on YouTube or TVLegends.com. People said he had a high-pitched voice; the interviewer has one of the most unappealingly effeminate voices I, for one, have ever heard. The way he talks is effeminate too; he doesn’t even try to sound masculine. Not that I think trying to do so would make him sound any better.
Rebecca Black’s speaking voice is very, very, very, very, very annoying.
Victoria Jackson is one of the only women that I can call a “tool,” which is a term that mostly applies to males.
I recently had a substitute teacher, a woman, whose voice was so backbreakingly nasal and grating that trying not to cringe was painful.
Share anything else?
Bit of a zombie, but two I forgot:
Everett Sloane (best male). My uncle (former stage actor and musician) and I share very fond impressions of his best work frequently. He had a sad life, but was one of the very best, in voice and also in appearance.
Agnes Moorehead (best female). Inimitable. Included lest one think I only included bombshells like Ava Gardner in my lists for their looks, rather than their voices. Dame Moorehead had it all, but wasn’t known as a beauty in the way Kay Francis or Jean Arthur were.
Really?! I think his voice is fine. It’s harsh-sounding, but it’s definitely not high-pitched. He had a rich gravelly baritone. I don’t find his commentary unwatchable in the least.
I don’t know if I could come up with 10, but I could listen to Sean Connery and Liam Neeson all day. Mike Rowe too. I don’t remember seeing anyone else mention Michael Dorn… man has a seriously sexy voice…
In that case, wanna tell me about some more? I’m always open to them.
I’ve kind of taken a long break from this thread. 
Brian Doyle-Murray, the voice of the Flying Dutchman on SpongeBob?! Nawh, his normal voice was okay. Very gruff-sounding. I think the audio of him in this video was of him on SNL or something.
As the Dutchman, though? Understandable. Still, I think you should replace Gilbert Gottfried with someone like Casey Affleck or David Schwimmer. Or perhaps, since you seem to have a knowledge for old-timers, Dennis Weaver?
