* Early in ''Anime/{{Paprika}}'', Dr Shima is driven insane by the BigBad and assimilated into the Parade making its way across the DreamLand. Fortunately, [[DreamWeaver Paprika]] is able to awaken him from the nightmare by melting into his body, causing him to [[InflatingBodyGag swell up like a balloon]], his voice getting progressively deeper and deeper as he does so until he's become a skyscraper-sized giant mumbling in surprise with a comically deep voice. Then he explodes and wakes up.

* On ''WesternAnimation/TheEmperorsNewGroove'', Yzma gets hit with one of her own transformation potions. At first she [[EvilLaugh laughs sinisterly]] in a low booming voice, making it seem like she's transformed into a giant monster; but then the smoke clears and [[spoiler:she is a tiny kitten. When she first speaks after transforming, she notes that her voice has become high and squeaky.]]
-->'''Yzma:''' Looking for this? [{{beat}}] Is that my voice? [clears throat] Is that ''my'' voice? [[ShrugTake Oh, well.]]

* In the finale of ''WesternAnimation/RockADoodle,'' the Grand Duke of Owls is defeated by Chanticleer and inexplicably shrunk to the size of a shrew; in the process, his voice is reduced to a childish, near-incomprehensible squeak.

* ''WesternAnimation/TurningRed'': When [[spoiler: Ming turns into a red panda, she becomes even taller than Toronto's [=SkyDome=]]], resulting in her voice becoming noticeably deeper as well.

[[folder: Film -- Live-Action]]

** This is averted in the [[Film/WillyWonkaAndTheChocolateFactory 1971 adaptation]] where Mike speaks normally after he's been shrunk.
* ''Film/{{The Fly|1958}}''. At the climax, the transformed fly with a human head has an extremely high-pitched voice as it screams for help. Of course, ArtisticLicenseBiology comes into play as the fly's head may have been a human's, but the fly's body didn't have the type of lungs that would move air over the human vocal cords. But the fact that it was trapped in a spiderweb and about to be eaten by the spider probably provided a ''lot'' of motivation for him to defy biology.

* ''Film/Hellboy2019'': Once [[BigBad Nimue]] decides [[TheDragon Gruagach]] has [[YouHaveOutlivedYourUsefulness outlived his usefulness]], she magically shrinks the formerly imposing [[PigMan boar man]] down to his original size, leaving him helplessly shrieking in a now high-pitched voice, "This ain't fair! [[PrecisionFStrike Foock you]], Hellboy!" [[spoiler: These double as ProfaneLastWords, because seconds after, Gruagach [[PopGoesTheHuman explodes]] from Nimue shrinking him.]]

* In the 2010 family film ''Film/TheToothFairy'', the protagonist (Dwayne Johnson) finds himself assigned to complete tasks as a tooth fairy to pay for his mistake and, when he uses shrinking gel for the first time to help retrieve a child's loose tooth undetected, his voice gets very high pitched as he shrinks down to size.
* Zig-zagged in ''Film/TheWitches1990'': after being transformed into mice, Luke and Bruno can still use their ordinary speaking voices, as was the case in the original book. In the finale, the same goes for the chef witch when she's exposed to Formula 86. However, when the Grand High Witch herself is finally overwhelmed by the potion and begins to visibly transform, her voice sounds increasingly high-pitched, until she finally shrinks down into a hideous-looking mouse that can only squeak incoherently. [[spoiler: Consequently, she can't be understood and is assumed to be just another unwanted mouse in the dining room, leading to her being hacked to death by Mr Stringer.]]

* The Termite of ''Series/TheBoys2019'' is essentially a SizeShifter a la Ant-Man; however, when he shrinks himself, his voice rises to a helium squeak - making some of his more profane lines even funnier in the process.
-->(''in chipmunk-speak'') FUCKING BITCH!
* {{Discussed|Trope}} in the 1997 television {{Pilot}} ''Film/JusticeLeagueOfAmerica''. Ray Palmer/The Atom, refers to resized vocal chords as being one of the drawbacks of his superpower. He finds it especially bothersome in instances where he returns to normal size, but his vocal chords don't regrow at the same rate, causing him to still sound like a chipmunk when he tries to speak.

** In "[[Recap/RedDwarfSeasonIVDNA D.N.A.]]", Lister tries to get Holly to use a DNA modification machine to turn him into a superhuman so that he can destroy a "mutton vindaloo beast". Unfortunately, he is instead made twelve inches tall, with his voice becoming squeaky and high-pitched to match - accomplished by Craig Charles putting on a silly voice.
** In "[[Recap/RedDwarfSeasonIVMeltdown Meltdown]]," Rimmer's hologram body is temporarily deactivated, leaving him as nothing but the miniscule light bee that normally projects him. He can still speak in this state - allowing him to express horror at Lister cheekily mock-eating the light bee and spitting it out - but his voice sounds tinny and helium-pitched.

* ''Series/XenaWarriorPrincess'': In ''Punch Lines'' Gabrielle gets shrunk to just a few inches high whereupon she speaks in a high pitched voice.

[[folder: Theatre]]

* In the finale of ''VideoGame/DayOfTheTentacle,'' Future Purple Tentacle gets extremely trigger-happy with his newly-completed shrinking ray, and with a little persuasion, can be talked into using it on Dr Fred... only for the bolt to rebound off Dr Fred's ever-present head mirror, hitting Purple and shrinking him to the size of a mouse. Immediately, his voice is reduced to a helium squeak - even though Bernard, Hoagie, and Laverne have all been shrunken at least twice and have never demonstrated such a voice.

* ''VideoGame/SlyCooperThievesInTime'': Toothpick [[HulkingOut grows in size whenever he's angry]], and when he does, he gets a much deeper voice.

* ''VideoGame/WarcraftIII:'' The Demon Hunter's Metamorphosis spell temporarily turns him into a towering pitch-black demon, using the same voicelines but much deeper.

[[folder: Web Animation]]
* In the ''WebAnimation/StrongBadEmail'' "[[Recap/StrongBadEmailE166Unnatural unnatural]]", Bubs somehow becomes giant, with a voice too deep to understand, and chaos results at the emergency town meeting as people try to figure out how to stop him. After recording his roars, playing them back at high speed and finding out that Bubs is warning not to eat his chicken wings, Strong Sad whips up an antidote of what he says is "the culinary opposite of chicken wings", a bowl of Kashi. It works[[note]]despite Bubs's chicken wings ultimately being found not to be the cause of his growth[[/note]], and as he gradually returns to normal, so does his voice.

When Meatwad eats the chip, Frylock has Shake shrink him [[FantasticVoyagePlot so he can go inside Meatwad to get it]]; however, Shake just laughs at Frylock's now high-pitched voice, then makes him fight a shrunken Carl - who is also sporting a high-pitched voice. Later, when Frylock, Carl, and Meatwad enter Shake's head by way of revenge, Meatwad's voice has also gone high-pitched.

* ''WesternAnimation/Ben10UltimateAlien'': Ben's voice changes according to the alien he turns into; big aliens like Four Arms, Humungosaur and the gigantic Way Big (an {{Expy}} of Ultraman) all have deep baritone voices, while turning into Nanomech reduces Ben's voice to a high-pitched squeak. Kevin comments that it's impossible to take Ben seriously with a such a voice; ironically, in "Inspector #13", he ends up getting turned into Nanomech and gains the same little voice.
* ''WesternAnimation/BugsBunny''
** In "WesternAnimation/LongHairedHare," Bugs Bunny decides to wreak havoc on opera tenor Giovanni Jones. One prank involves prepping the man to go on stage with some throat spray laced with bitter alum powder. As the tenor begins singing "Figaro!" the alum kicks in, shrinking his head by degrees until its the size of a plum. His Figaros successively pitch upward as his head size scales downward, to the point where this tenor would fit right in with ''WesternAnimation/AlvinAndTheChipmunks''.
** In "WesternAnimation/RabbitRampage", an off-screen animator torments Bugs by erasing his head, then painting a pumpkin head, and when Bugs protests, he repaints his true head on a much smaller scale.

The foghorn alarm clock is sounding as it shrinks, the foghorn sounding higher and higher the smaller it gets.
