A character will open his mouth to speak, and the instant he does, you immediately know that this character is stupid. Whether he's an over-muscled Mook or the Plucky Comic Relief, the one thing you can tell just by his voice is the fact that his elevator just doesn't go all the way to the top floor.
Very common in animated works, because allegedly such an obvious characterization tool appeals to children. In The Golden Age of Animation, this sort of voice was used a lot by characters who were a parody of Lennie from the film adaptation of Of Mice & Men.
When the character is male, generally expect a halting voice in the low registers, or else a high-pitched, nasally quavering, with most sentences beginning with the word 'duh'. When the character is female, expect a high-pitched nasally whine or an even higher-pitched squeak-fest. Often, characters with this voice will use poor grammar. Male characters often substitute the t or d sounds for the th sound, like saying "dat" for "that." A Valley Girl accent helps for female ditzes. May occasionally utter a Stupidly Long Filler Sound.
- Dorodoron's voice from Futari wa Pretty Cure Splash★Star sounds very similar to this type, sounding rather like Grounder from Adventures of Sonic the Hedgehog would if he was speaking Japanese.
- Dragon Ball Z:
- In the original Japanese, Son Goku is voiced with the equivalent of a country hick accent. This is an essential part of his character for Japanese viewers (along with generally sounding like a child), but was excised in the English dub.
- The French dub is notable for giving an extraordinarily nasal voice to Vegeta of all people. It's been theorized that not having read the entire story, the voice actors had originally expected him to be a one-time villain, and thus gave him a generic cartoon villain voice; cue HeelFace Turn... It was never a "moron" voice though, more of a "evil schemer with permanent Psychotic Smirk" voice.
- Recoome of the Ginyu Force; the "dumb-as-nails Psychopathic Manchild" vs. "hammy sadist who's just toying with you" ratio depends on who's voicing him.
- Bear in the English dub of Yo Kai Watch, which makes scene considering what what type of character he is. Also, his English voice actor is unknown at this time though.

- Nick in 30 Minutes or Less.
- Sam in i am sam.

- Referenced in the novel version of Flowers for Algernon; Charlie notes that he had a stupid-sounding voice before his increase in intelligence, and he lapses back into it whenever he gets drunk.
- Discworld trolls tend to have this type of voice. Detritus, the troll that tends to show up the most, says "dis," "dat" and "der" instead of "this", "that", and "the." (He also sometimes replaces "th" with "f", for example "fink" instead of "think".)
- M-O-O-N, that spells Tom Cullen from The Stand.
- Crabbe and Goyle from the Harry Potter books. Both are dim-witted lackeys of Harry Potter's school nemesis Draco Malfoy. Even Malfoy himself at one point describes Goyle as being so slow that if he were any slower, he'd be going backwards. Crabbe speaks mainly a soft but deep grunt, Goyle speaks in a low, raspy voice. They sound equally dumb in the film versions.
- Pets, Aiku and inspector Kukeke from Wremja.
- Michael Westen on Burn Notice occasionally affects something resembling this accent for his "Bubba"-ish characters.
- The Pakleds in Star Trek: The Next Generation.
- The Ogrons in Doctor Who should be this, with one exception. In Day of the Daleks, the Controller confronts two Ogrons. The first one says, "We found...and destroyed...the enemy."

- Subverted in The Big Bang Theory: Bernadette speaks with a high, nasal, squeaky Dumb Blonde voice, but has a doctorate in Microbiology.
- Rom from Star Trek: Deep Space Nine has one.

- Lew Zealand has one, not because he's dumb, but rather a Cloudcuckoolander. He's also dumb, but it's not his main problem.
- Beauregard has one as well.

"MOY BRAIN HURTS! WE FORGOT THE ANESTHETIC!"

- Lilly from Annie.

- In "Buddy's Blues" from Follies, the "Margie" and "Sally" caricatures talk this way. Mostly they just echo Buddy's words.
- The Wizard from Wicked, who describes himself as "This corn fed hick / Who thought it might be keen / To build a town of green / And a road of yellow brick." Of course, his seeming simple naivete and paternal air is hiding something much darker...

- Ogres and Peasants from Warcraft II and III.

- Mr Fossey from The Curse of Monkey Island.
- Willard and Mog from Jak and Daxter.
- Boastful: While elcor from Mass Effect have this tone of voice down to a T with the low, "drooping" pitch and lazy inflection, they subvert this trope by being as intelligent as any other species and sometimes prone to Spock Speak to make up for the lack of emotion in their voices.
- Goliaths in Borderlands 2, the Giant Mook enemy type of the Bandits. Strangely, their speech is a lot less slurred when you make them angry.
- Sir Daniel from the MediEvil series and Playstation All Stars Battle Royale. However, this one is justified due to the fact that he has no lower jaw. And he's not really stupid, just very clumsy.
- In the English dub of Trouble Witches NEO!, Pril Patowle is given such a voice, making her sound incredibly slow and dim. Here, listen for yourself.
- In Kingdom Hearts II, you have Organization XIII, whose members generally sound fairly dangerous... except for Demyx, who both acts and sounds like a moron... at least until it's time to get serious.
- Investi-Gator: The Case of the Big Crime: Investi-Gator, who is rather incompetent, has a deep, goofy-sounding voice for his Speaking Simlish.
- Homestar Runner:
- Strong Mad from speaks in an extremely exaggerated version of this trope, Played for Laughs. Most of his dialogue is nigh-unintelligible growls, but if you listen closely he is saying actual words...probably. Homestar Runner himself is a (somewhat) more subdued version of this trope.
- Homsar. Dear God, HOMSAR.
- The two titular leads of Baman Piderman.
- Jimbob from GEOWeasel speaks in a low-pitched voice.
- Caboose from Red vs. Blue. Early episodes didn't have it, but Joel Heyman eventually got the voice to a "obvious moron" one, and the writing ramped up the character's stupidity as well. Joel also explained that Caboose speaks like a human does so to a dog or cat, "only everything to him is an animal".
- In his review of Metal Gear Solid V: Ground Zeroes, Yahtzee adopts this kind of voice to represent the Metal Gear franchise as a whole, to reflect how he views it as being lovably stupid.
Yahtzee: Hey, Metal Gear? Why did you pretend MGS 2 would be about Solid Snake, then replace him twenty minutes in with a cross between an albino Barbie doll and Wesley Crusher?
'Metal Gear': Duh, I'm sorry. I just wanted everyone to meet this cool new character I made up. Hes a cyborg and his nipples turn into shurikens!
Yahtzee: Hey, Metal Gear? Why are all these emotionally traumatised young women thrusting their butts at the camera?
'Metal Gear': Duh, I'm sorry. Looking at bums makes my willy feel nice.
- The Flap-Jacks from CarnEvil have a rather Goofy-esque voice.
- In The Order of the Stick, half-orc Thog the Dumb Muscle Bumbling Sidekick is implied to sound like a moron just as much as he is one. His general speech pattern is Hulk Speak, the text of his speech bubbles is emboldened and transcribed in all lowercase letters and to top it all off he's a Third-Person Person. It was later revealed that all orcs speak like this, though they can apparently grow out of it through grammar lessons.
- The Nostalgia Chick did it in her review of Spice World.
Mel B: Girl power, feminism, you know what I mean?
Chick: [in the stupidest voice she can manage] No. Do you?
- The voice of the Wii in this Dreamcast vs Wii video.
- Jeffy from SuperMarioLogan
- Don't Hug Me I'm Scared:
- Yellow Guy uses this voice, only emphasized by his short stature, noticeable slowness and status as a Butt-Monkey.
- The Spinach Can from the fifth installment has one, which emphasizes the low quality of his/her song and helps invalidate his/her flimsy health advise.
- Unlike the five preceding videos, the sixth video's Teacher is almost immediately revealed to be malicious and ignorant, and as such, the Lamp's voice is quite slurred in order to immediately convey his incompetence.
- DC Super Hero Girls: Combine her high-pitched comical voice and her tendency not to be a deep thinker and you have Harley Quinn.
- In The Proving Grounds: The Naming of Swords by Jeff C Wells, when Kelli Thunderhold, Paladin of Righteousness, is horrified to learn her sword's name is a Double Entendre
Kelli: Stupid friggin' elves. Dad always told me not to buy an elf sword. He was all like, 'It's meteoric iron or nothing, Kelli!' And heres me: 'Hurr durr durr, Im gonna go on the Aethernet and buy an elf sword because I love mithril! Holy rainbow slaadcrap I love mithril so farking much!
Eidey: This keeps remaining awesome. I love the voice you do when you're being 'you except stupid.'
- Jon Bois: In Pretty Good: "The Dumbest Boy Alive", TheJosh is given this voice to go along with his insistence that working out every other day doesn't average to 3.5 workouts per week. Near the end of the video, TheJosh returns to say he was trolling and Jon drops the voice.
- Hyuck! Goofy (1932), first appearing in the early days of the sound era, may have been the very first cartoon character with a voice like this. Bill Farmer is capable of pulling off the voice while still giving Goofy an impressive emotional range in modern productions.
- Homer Simpson is the leader of a small crowd of such characters from The Simpsons.
- Barney Gumble has an exaggerated one because he's almost always drunk.
- Parodied/subverted with Oxford "Ox" Haas, one of the soldiers Grampa Simpson served with in World War II in "The Curse of the Flying Hellfish." He spoke with this voice, and looked exactly like the kind of person who would.
Burns: How many of you are familiar with the concept of a "Tontine"?
[beat; all stare at Burns silently, until Ox raises his hand]
Burns: All right, Ox. Why don't you take us through it?
Ox: Duh, essentially, we all enter into a contract whereby the last surviving participant becomes the sole possessor of...all them purty pictures.
- In one Imagine Spot where Lisa imagines her future after losing her intelligence, she's inexplicably gained a southern accent.
- Used in the Futurama episode "Fear of a Bot Planet" where the crew meets the council of robot elders. They promote human hunts to distract from their bigger problems.

Elder 2: And an incompetent group of robot elders.
Elder 3: Duh, that's for sure.
Elder 1: Quiet, Jimmy!
- Igner (of Mom's three sons) can also qualify as this. The irony comes in when we learn his father is Professor Farnsworth!
- Patrick Star from SpongeBob SquarePants.
- Peter Browngardt, aka Uncle Grandpa, makes a guest appearance in the Season 11 episode "Patrick's Coupon" as the Ice Cream King and used Uncle G's voice. The similarity between the voices is uncanny. In the German version, they brought back Patrick's original German voice to voice the Ice Cream King.
- Uncle Grandpa talks in this voice all the time.
- Jack from The Nutshack
- Pinky from Pinky and the Brain.
- Mungo from Heathcliff and the Catillac Cats.
- Any character from Looney Tunes that parodies Lennie Smalls, such as Hugo the Abominable Snowman from "The Abominable Snow-Rabbit" and Benny the cat from "Hoppy-Go-Lucky" (who even calls Sylvester "George"). Here is a compilation of such characters.
- Also Beaky Buzzard, and Junyor Bear, and Pete Puma, who incidentally were all voiced by Stan Freberg.
- Mugsy of Rocky and Mugsy.
- The identically-sounding Runt and Ralph from Animaniacs.
- Various minor Ren & Stimpy Show characters, such as Lump and Loaf. Not to mention Stimpy himself.
- Chris Griffin from Family Guy. This wasn't actually the intention; Seth Green went into the audition and decided to do his impression of Ted Levine as Buffalo Bill in The Silence of the Lambs as a joke, but ended up getting the part. Inevitably, this is referenced in a cut-away gag where Chris does an impression of Buffalo Bill dancing naked (and tucked back) in front of a mirror.
- And in the original version of the Pilot, his voice is more of a typical low-pitched simpleton voice.
- For that matter, Barry in American Dad!, who has the same voice, only slightly more affected. Well, it isn't his real voice but the voice he has while heavily drugged to suppress his true, evil personality. His real voice is a cultured accent.
- Cleveland Jr. from The Cleveland Show.
- Brittany, from Daria.
- Grounder in Adventures of Sonic the Hedgehog. His voice changes to Received Pronunciation when he gets a genius chip.
- Bebop and Rocksteady in the '80s Teenage Mutant Ninja Turtles cartoon.
- Luanne and Bill from King of the Hill.
- Linsday from Total Drama.
- Ed (single "d") and May from Ed, Edd n Eddy.
- Ringo Starr from The Beatles. The actual Ringo wasn't happy about it at all.
- Junior from Tex Avery's George and Junior shorts
- Heffer from Rocko's Modern Life.
- Stinky from Hey Arnold!, but he's not a complete idiot, just comically awkward.
- Willy White from Doug.
- Waffle from Catscratch.
- Brain from Top Cat.
- Megawatt from ¡Mucha Lucha!.
- Scooby Dum from Scooby-Doo.
- Rocky from Avenger Penguins.
- Meathead from Tex Avery's Screwy Squirrel cartoons.
- Snails and Derpy Hooves from My Little Pony: Friendship Is Magic. Derpy is a strange case; Tabitha St. Germain was, apparently, originally under the impression that Derpy was meant to be a boy. So Derpy was never actually intended to have this trope; she just got one because Tabitha isn't very good at Crossdressing Voices.
- Tred Possum in Get Muggsy!.
- Chief from Tak and the Power of Juju.
- Gerold from The Goode Family.
- Ranger Stu from Squirrel Boy.
- Wally Gator as he appeared in Harvey Birdman, Attorney at Law.

- Nester, Momma, Paddy, Buck, Dan Duck and Paulie from Scaredy Squirrel.
- Mr. Flea from Pearlie.
- Airhead, and no doubt several other characters, in Filmation's Ghostbusters.
- Officer Barbrady from South Park combines this with No Indoor Voice.
- Shelley also talks this way (though it may just be a Speech Impediment caused by cumbersome dental work).
- Reggie Bullnerd from ChalkZone.
- Peppermint Larry from The Marvelous Misadventures of Flapjack.
- Vlad from Shuriken School.
- Ticket Guy from the Regular Show episode "Caffinated Concert Tickets".
- Mole from Mr. Bogus, as well as Bogus himself.
- Hubert Test from Johnny Test.
- Tooley from Motorcity.
- On the few occasions Tom spoke, it was this voice more often than not.
- Hi-Riser from Wheelie and the Chopper Bunch.
- Lumpy from Happy Tree Friends.
- Richard from The Amazing World of Gumball. Sussie the Chinikin is an even more extreme version (but only when she's voiced by Fergus Craig; her Aurelie Charbonnier voice is more calm and sounds mostly like a normal girl.
- Scorpia from She-Ra: Princess of Power has one, though the character didn't seem particularly stupid.note
- Lilly from Timothy Goes to School a rare female example. However she loses this voice when she get's very upset,ashamed, or annoyed.
- From the same show the duo Frank and Frank.
- From Camp Lazlo we have the Dung Beetles, Chip and Skip. There's also Clam who subverts the trope as he only behaves like one.
- Shirley from Shaun the Sheep. Seeing that she's the Fat Idiot of the idiot, her voice is low and raspy.
- Harley Quinn in Batman: The Animated Series spoke in the female variation, complete with a Jersey-like accent. In the episode "Mad Love", it's revealed that before she was brainwashed by the Joker, her she spoke in a lower pitched voice and the accent was more subtle. Also subverted; not only can she switch to a deeper, un-accented voice at will (as shown in the episode, "The Man Who Killed Batman"), but she's actually highly intelligent, not only having been a psychologist before her brainwashing, but able to pull off a perfectly good and understated gem heist on her own. The implication is that she acts like this because the Joker prefers for her to act stupid.
- As in the comics, Moose in The Archie Show and Archie's Funhouse is voiced this way. Same goes for Big Ethel.
- Wild Card and the Watchdog janitor in the Wander over Yonder episode "The Big Job".
- Baby Bugs, Baby Taz and Baby Sylvester in Baby Looney Tunes.
- Beezy from Jimmy Two-Shoes. According to his voice actor, Brian Froud, it was originally a bad impression of Brad Garrett that then just evolved from there.
- Lenny from Freaktown is basically Beezy as a giant mantis (ironically Lenny's voice actor was Jimmy himself).
- Rainbow Brite has Lurky, Murky D Ismal's hairy assistant.
Duh, I am Mo-Ron.note
- Gil from Cloudy with a Chance of Meatballs.
- Cosmo from The Fairly OddParents has an extremely high pitched voice. In fact, thanks to his Flanderisation from "goofy but smart" to "straight up idiot", his voice got progressively higher. In the original Oh Yeah! Cartoons shorts, he was pretty intelligent ( probably even smarter than WANDA ) and had a deep and smooth voice. In first few seasons, when he was goofier and less intelligent, but not to terrible levels, he had higher voice, but it still had a natural tone to it. In later seasons, when he became Too Dumb to Live, he has voice so high you would swear that either his original voice actor got replaced or that his voice is digitally edited to sound like that.
- On My Friend Rabbit, even various summary listings describe the character of Thunder as being "slower" than the other characters, and he has this sort of voice to match.
- On Mack & Moxy, despite being a somewhat downplayed version of the Moose Are Idiots characterization, Mack speaks this way.
- Discussed in The Critic, when Jay's boss, Duke Phillips (who speaks with a southern accent) meets Jay's new assistant, Alice (who is also southern). He notes to her about how as southerners, they have to work extra hard in New York because as soon as people hear them talk, they're immediately dismissed as illiterate, country bumpkins.
- Inspector Gadget: Spreads across several iterations of the franchise—the larger MAD henchmen tend to talk like this. Corporal Capeman, who somehow manages to be even dumber than Gadget, also speaks with this kind of a voice.
- On Butterbean's Cafe, the monkey minions of show Card-Carrying Villain Ms. Maralady, Spork and Spatch, both look and act really stupid and have this voice to match.
- Rick the crazy chicken guy and Gus the sound mixer in Be Cool, Scooby-Doo!.
- Steve the Neat Freak boss from ''Bordertown'.
- Big Billy of the Gangrene Gang from The Powerpuff Girls he is easily the least intelligent member of the gang.
- From the rare times he says something other than Dinosaur, No or Why, George from Peppa Pig sounds like this.
- Originally, Ed from Ed, Edd n Eddy had a voice similar to a frat boy, but his Vocal Evolution as the series went on led his voice to become more like this.
- Kuchipatchi has this voice in Tamagotchi Video Adventures, contrasting with his appearances in later Tamagotchi media where he has a much higher-pitched voice.
- Actor Bill Fagerbakke (who is quite intelligent, urbane, and friendly in person) has made a career out of this trope, and he does it by only very slightly exaggerating the way he naturally speaks. In addition to voicing Patrick Star in Spongebob Squarepants, Broadway in Gargoyles and Bulkhead in Transformers Animated, Fagerbakke played Tom Cullen in the miniseries adaptation of Stephen King's The Stand and Dauber on Coach; all of them had the "big dumb doofus" form of this trope.
- Similar to the above, the French actor and singer Bourvil made his Signature Style of playing Butt Monkeys speaking like this, also by exaggerating his normal speech pattern. Though it is notable that he was equally good in dramatic roles.
- Karl Pilkington of The Ricky Gervais Show and An Idiot Abroad sounds notably less intelligent than Ricky and Steve...naturally, he is.
- He is intelligent enough sounding for a working class guy from Manchester though.
- Studies done on rural American Accents found that a disproportionate amount of preschoolers who spoke with vernacular rural accents (Vermont, Appalachia, etc.) were placed in special education classes for it.
