Vocal Dissonance in animated movies.
- Disney Animated Canon:
- Scamp from Lady and the Tramp II: Scamp's Adventure is a young looking puppy who sounds more like a 15- or 16-year-old. His sisters sound noticeably more appropriate than him. Angel also has a deep voice for her looks.
- Chicken Little:
- Chicken Little looks like he should sound like a little kid, so it's a bit jarring to hear him with the voice of Zach Braff.
- Likewise with Abby Mallard; she appears to be much younger than 13, though her voice sounds a little older than that (probably around the late teens.)
- In The Princess and the Frog, the hyperactive Charlotte has a mostly squeaky voice that drops when whenever she gets too excited or is trying to be seductive. The Canadian French dub version of her, however, has probably been eating cigarettes her entire life.
- Sgt. Calhoun from Wreck-It Ralph appears to be a beautiful young woman somewhere in her 20's or 30's but she has the gruff voice of Jane Lynch. Additionally, the Sugar Rush racers sound like teenagers instead of kids.
- Finnick from Zootopia is a cute, little fennec fox... with the voice of Tommy "Tiny" Lister, a man known for playing scary thugs and brutes, like Deebo from Friday.
- The original 1953 Danish dub of Peter Pan has John voiced by a man, unlike the English original (and the 1998 Danish re-dub) which has him voiced by a child actor.
- Most of the Lost Boys were voiced by children, however Cubby the one in the bear costume due to being voiced by a man in his 20's sounds more like a teenager.
- In the original 1962 Hungarian dub of Pinocchio, Jiminy Cricket's voice is much deeper compared to the original version.
- In Bolt, Penny's voice sounds too old for her design. This is because Miley Cyrus (who was fifteen when the film was made) wasn't originally tapped to record — it was Chloë Grace Moretz (who was ten when it was made) before Disney decided to re-record most of her lines, though Moretz still voices Penny as a kid.
- In Snow White and the Seven Dwarfs Dopey, who looks and acts like a child, lets out a grown man's scream when he sees Snow White under the covers of the Dwarves beds.
- Pixar:
- In Finding Nemo, during the montage of Marlin's story being passed along, one scene shows a small fish telling the story to a larger fish. The small fish has a deep, booming voice, while the big fish has a high, squeaky voice. And the squeaky big fish's phrase is: "Golly, that's amazing!"
- Alpha the Doberman in Up has a high-pitched voice because his voice collar is malfunctioning. When the collar is fixed later, Alpha has a voice much more appropriate to his appearance, causing Russell to comment he liked the old voice better. In the climax, Dug inadvertently causes it to break again.
- In Inside Out, the mind worker/actor who does Riley's voice in the Dream Productions studio is stocky and bearded, yet speaks his lines in a perfect little girl's voice.
- In Turning Red, this is downplayed since Mei has the normal voice of a pubescent girl (even if sounding a bit older than 13), though her happy appearance in promotional material and merchandising makes her appear more like a Genki Girl and/or Cheerful Child, so hearing her mature voice may be a bit unexpected. Justified since her VA was 16 during the dialog recordings for the movie.
- DreamWorks Animation:
- Tai Lung of Kung Fu Panda is a ripped anthro snow leopard who has just finished tearing apart a prison... and then speaks in a smooth British accent, courtesy of Ian McShane.
- In Rise of the Guardians, Chris Pine (age 32) voices Jack Frost (who appears to be about 14) with his normal voice.
- In How to Train Your Dragon 2, Jay Baruchel's voice is very distracting when it's coming out of the older Hiccup.
- In Penguins of Madagascar, when Skipper, Kowalski, and Rico are shown as chicks they sound the same as their adult selves.
- In Puss in Boots (2011), during Puss' childhood flashback, he didn't really talk. But once he did, he sounded the same as he did when he's an adult. He was only a kitten by the way. In fact Puss in general is this trope as one wouldn't expect a cute little kitty to havre a suave, deep voice like his.
- In Captain Underpants: The First Epic Movie, George and Harold are voiced by Kevin Hart and Thomas Middleditch, despite being ten-year-olds. The Netflix spin-off series averts this by having them being voiced by actual kids.
- In The Boss Baby: Family Business when Tim becomes a child again he retains his adult voice rather than having a child actor voice him, also several of the babies including the titular Boss Baby have adult voices.
- In The Amazing Feats of Young Hercules, Falina (as seen in her human form) looks to be a young girl in her late teens or twenties... but her voice is very scratchy and sounds more like that of a middle-aged woman who smokes heavily.
- For some reason, in the DVD version of An American Tail, two of the three Jerkass orphans who taunt Fievel towards the end are re-dubbed by adult men.
- During the montage song of Fievel being carried through the desert in a tumbleweed in An American Tail: Fievel Goes West, an adorable baby bird opens its beak. . . and suddenly belts out, "Ride 'em in, rawhide!" in a very deep voice.
- In Batman: Gotham Knight in the segment "Field Test", Kevin Conroy's deep voice doesn't really fit this Bruce Wayne's effeminate appearance.
- One of the gags in Bébé's Kids is that the baby is voiced by Tone Loc. He's famous for his deeeeeeep voice.
- In the animated version of The Cat in the Hat, one of the Cat's little helpers Thing One had the deep bass voice of Thurl Ravenscroft, probably best known for voicing Tony the Tiger in Frosted Flakes commercials.
- Flushed Away has a quick gag where the tiniest, cutest slug in the Greek Chorus sings in a deep, resonant bass.
- Cindy Lou Who in The Grinch (2018) has the voice of a young boy even though she's female.
- In Jay and Silent Bob's Super Groovy Cartoon Movie we have the villain Cocknocker a chubby man in a blue costume with "Anime Hair" who sounds like Bubbles from The Powerpuff Girls, lampshaded by Kevin Smith who says he hired Tara Strong to voice him to subvert viewers who expected to hear Mark Hamill who played him in Jay and Silent Bob Strike Back, and to please the brony fanbase.
- The titular character from The Littlest Light on the Christmas Tree is a small and quiet Christmas lightbulb/ornament that comes to life, and looks like he should sound cute, but when he finally ends up singing his musical number ("I Can Shine"), he sounds like a cheerful young man.
- The Lorax (2012) has a main character who is twelve years old, but voiced by Zac Efron, who makes him sound like he's at least in his mid-twenties.
- The Mitchells vs. the Machines has Aaron Mitchell, the youngest sibling in the Mitchell family. Despite being 8 years old (according to the movie's script), he has the voice of a grown-up man, courtesy of the movie's director Mike Rianda. Subverted in the Brazilian, Castilian Spanish and French dubs, in which he's voiced by an actual child.
- Mei from the One Stormy Night movie has the type of deep voice you'd expect for an adult male. He's a cute, androgynous little goat who wears a pink scarf so his voice can be a bit jarring.
- In Chuck Jones' The Phantom Tollbooth The Runt at the End of King Azaz's royal palace guards has the deepest voice.
- The Polar Express features mostly children as characters, and most of them sound like kids... Except for the Know-It-All kid, who is voiced by a grown man (Eddie Deezen, to be precise) and sounds nothing like a young child.
- In the Monica's Gang movie “The Princess and the Robot”, during the gladiator battle the tallest and most muscular of the rabbit warriors has a very high pitched voice.
- Rapsittie Street Kids: Believe in Santa:
- The characters are supposed to be around 10 years old but sound like teenagers or adults (maybe not too unfitting when it comes to the girls if at all, but it is unfitting for the boys). It also doesn't help that most of them look like teenagers rather than kids!
- Inverted with Nancy Cartwright's character. She uses her Nelson voice for the role but the problem is, he looks like he's 14 so hearing that voice out of that character comes off as weird!
- Averted with Grey Delisle, who actually does a convincing little girl voice while playing a little girl.
- Some of the Smurfs (Greedy, Lazy, Grouchy, and Hefty) in the UK English dub of The Smurfs and the Magic Flute had extremely deep voices (with Lazy's being the deepest). For the US dub, their voices are a bit higher, but still pretty deep (with the exception of Greedy's). Averted with Grouchy in the Greek dub, in which he has a Mickey Mouse-like voice.
- The joke was in the original cut of The Thief and the Cobbler that one did not expect the small, scrawny, shy Tack to have such a deep voice (provided by Sean Connery for one line at the end); however, the voices given to him by Matthew Broderick and Steve Lively match his appearance in the bowdlerised versions.
- Thomas and the Magic Railroad: James and Percy are voiced by Susan Roman and Linda Ballantyne from Sailor Moon, making them sound too feminine for male locomotives. For Percy, it at least makes sense for him to be voiced by a woman due to him being the youngest of the Steam Team, but James' voice is quite misfitting due to him clearly being an adult engine. Interestingly, they were originally going to be voiced by Michael Angelis, the narrator of Thomas & Friends around the time the film was in production (having replaced Ringo Starr as the narrator in 1991), but test audiences thought he sounded too mature for either of them.
- Tom and Jerry:
- During the Big-Lipped Alligator Moment from Tom and Jerry: The Movie, the smallest alley cat that pesters the titular cat-and-mouse duo actually speaks in a low, gruff voice; while the largest alley cat actually speaks in a high, squeaky voice. This is apparently more obvious in the Canadian French dub in which the large alley cat is actually voiced by a woman.
- One of the racers in Tom and Jerry: The Fast and the Furry is Gorthan, Destroyer of Light, a Tin Tyrant with Tom Kenny's high voice.
- The main character Hayden from Troll Land is a 12- or 13-year-old boy voiced by then 42-year-old Jerry O'Connell who sounds more like a man in his twenties because of this.
- Yellow Submarine: As the sub ventures through the Sea of Time, the Beatles regress to childhood and Old Fred to young adulthood. The Beatles' voices (Paul Angelis, Geoffrey Hughes, John Clive) as children are still the same as their adult voices, and Old Fred's (Lance Percival) didn't change either.
- The Super Mario Bros. Movie:
- The penguin king, despite being a penguin, has a surprisingly deep and regal voice courtesy of Khary Payton. His voice is ironically almost as deep as Bowser's.
- Most of the Toads have the exact kind of high-pitched voices you would expect from such creatures. However, the proprietor of the Antiques shop has a deeper and raspier voice, and one blue Toad in Peach's court has a deep and dignified voice (courtesy of Eric Bauza).
