* Umaru from ''Manga/HimoutoUmaruChan'' deliberately changes her voice between her "outside" and "inside" personas. She sounds like a mature and proper teenage girl while "outside" in public, while in private her voice is more high-pitched and childish to reflect how she's really an immature ClosetGeek.

Compare PowerMakesYourVoiceDeep, when accessing your power (and, usually, disguising yourself in the process) grants you a different voice. Compare ShiftingVoiceOfMadness.

* Parodied in ''Comicbook/TheSimpsons'' comics where Milhouse takes up the Bartman mantle after Bart quit due to a smear campaign and he talks about using "that dark, raspy voice that makes him sound like on of [Bart's] aunts."

* ''VideoGame/LaytonsMysteryJourneyKatrielleAndTheMillionairesConspiracy'': [[spoiler:Cesar Chance]]'s voice is quite nasally normally, but as Ratman, he has a BadassBaritone. Shown in most adorable fashion when he's [[GoodParents taking care of his newborn baby]].
--> '''[[spoiler:Chance]]:''' Make way, make way! Here comes (turns on the BadassBaritone) Ratman, to save the day.

* In the 1960s ''[[WesternAnimation/SpiderMan1967 Spider-Man]]'' series, Spider-Man's speaking voice is about an octave deeper than Peter Parker's, even when there's no need for it (e.g., when he's talking to himself and there's nobody else around).

* ImpliedTrope in the ''VideoGame/{{Neptunia}}'' series when it comes to Uni, whose voice becomes slightly but noticably deeper as [[SuperMode Black Sister]]. Uni is one of only a handful of characters whose voice changes while in HDD, but unlike the others, she doesn't have the excuse of [[OlderAlterEgo becoming noticably older physically]] like Neptune, Plutia, and Peashy, as she is the only character who actually ''shrinks'' when in HDD. Combine this with the fact that none of the other CPU Candidates - Nepgear, Rom, and Ram - have their voices change at all when in HDD, and the implication is that Uni deliberately deepens her voice to compensate.
** [[PlayingWithATrope Played With]] when it comes to Uzume/Orange Heart. As Uzume, she has a deep tomboy voice, and as Orange Heart, she has a high-pitched voice to go with her more childish, innocent personality. It is later revealed that the latter is her true personality, and the former is a façade she puts on to keep people's hopes up, implying that, she too, intentionally deepens her voice.

* ''WesternAnimation/SupermanTheatricalCartoons'' Clark Kent would always do this when changing into Superman.
-->'''Clark Kent:''' This looks like a job...
-->'''Superman:''' [[PowerMakesYourVoiceDeep For Superman.]]

* ''WesternAnimation/MiraculousLadybug'':
** Gabriel Agreste drops his voice an octave when he is dressed as Hawk Moth, even when he's by himself.
** American heroes Knightowl and Sparrow have very different voices when heroes than when in civilian mode. [[spoiler:It helps to hide that both are female]].

* Lelouch from ''Anime/CodeGeass'' speaks with his regular teenager voice when in his civilian, RichIdiotWithNoDayJob persona, but switches to a much deeper, booming (read: ''much'' more epic) voice when acting as the RebelLeader Zero.

* In ''WesternAnimation/BatmanTheAnimatedSeries'', Batman has a lower, more serious voice than Bruce Wayne. The shift is far more subtle than in the [[Film/TheDarkKnightTrilogy Nolan films]], but he seems to put it on whenever he puts the suit on, even when he's talking to people who know he is Bruce Wayne. However, from ''The New Batman Adventures'' onward in the DCAU, Bruce's voice shifted down to sound more like Batman than it used to.
** This gets PlayedForLaughs when Superman has to impersonate Batman when he goes missing (having been kidnapped by Brainiac). His voice is spot on, [[BadBadActing his mannerisms are not]]. Supes then creeps out Robin when he shows that he can do his voice too, thanks to his enhanced muscular control in his voice box. Superman drops the Batman growl during his fight with Bane, grunting in pain in his own voice.

If your secret identity includes [[{{Crossdresser}} disguising as the other sex]], this becomes especially necessary, since otherwise the voice will most likely be a [[LarynxDissonance dead giveaway]].

* ''LightNovel/SwordArtOnline'': In the anime adaptation of the Phantom Bullet arc, the normally shy Shino speaks in a slightly deeper, rougher voice when in-game as the ColdSniper Sinon. Meanwhile the DudeLooksLikeALady avatar that Kirito receives in this arc ''initially'' distorts his voice into a falsetto, but [[OohMeAccentsSlipping it's forgotten]] as the story gets more serious. In addition, Death Gun wears a mask that deepens and distorts his voice. [[spoiler:This helps conceal the fact that "Death Gun" is actually a shared identity. When Death Gun first appears, his manner of speaking is highly dramatic due to him being controlled by the young and impulsive Kyoji Shinkawa; but when Kirito encounters him later, his cadence is much softer and calmer, since he is controlled by the more experienced elder brother Shouichi.]]
** In the spinoff ''LightNovel/SwordArtOnlineAlternativeGunGaleOnline'', a number of characters have higher or lower voices in-game due to using avatars with a vastly different body type from their own, with one exception of Miyu who keeps her real life voice and mannerism when playing her small-sized avatar Fukaziroh.

* Umaru from ''Manga/HimoutoUmaruChan'' changes her voice between her "outside" and "inside" personas. She sounds like a mature and proper teenage girl while "outside" in public, while in private her voice is more high-pitched and childish to reflect how she's really an immature ClosetGeek.

* ''VideoGame/TrailsSeries'':
** Done by two characters in ''VideoGame/TheLegendOfHeroesTrailsOfColdSteel'': "C" wears a helmet that modulates his voice, disguising his true identity of [[spoiler:Crow]], and [[spoiler:Thomas]] notably adopts a deeper, more serious tone when he drops his facade of being a [[spoiler:carefree, lackadaisical teacher and reveals he's actually the Second Dominion of the Gralsritter]].
** In ''VideoGame/TheLegendOfHeroesTrailsIntoReverie'', the third protagonist of the game, "C", wears a helmet that also modulates his voice. The identity of this person turns out to be [[spoiler:[[PromotedToPlayable Rufus Albarea]].]]

* ''Film/Masquerade2021'': The burglars use voice disguisers. This is especially effective with [[spoiler: Daniel]]. Also, the fact that Rose ''doesn't'' disguise her voice [[spoiler: is a hint she's not part of the same crew]].

* In ''Series/ChoujinkiMetalder,'' Tsurugi has a completely different voice actor for when he’s transformed. In the final episode, [[spoiler: it’s a BittersweetEnding where he loses his powers but can’t return to his human form ever again, and Metalder speaking with the Tsurugi voice now ''really'' hammers it in.]]

* ''WesternAnimation/MiraculousLadybug'' Gabriel Agreste drops his voice an octave when he is dressed as Hawk Moth, even when he's by himself.

** The deepening of Bruce Wayne's voice when he puts on the Batman costume is taken UpToEleven- he sounds like he's gargling with gravel. Oddly, he still does this even when he's talking to people as Batman who know his secret identity.

* ''WesternAnimation/SupermanTheatricalCartoons Clark Kent would always do this when changing into Superman.

* ''Film/HeyArnold:TheMovie'', the mysterious informant “Deep Voice” has an altered low pitched voice. Turns out that Deep Voice is [[spoiler:Helga Pataki who used a voice modulator]].

* Hei of ''Anime/DarkerThanBlack'' has his voice deepen when he goes from his persona as [[NiceGuy Li]] into his identity as the "Black Reaper". It's not for nothing they call him [[FanNickname Chinese Electric Batman]].
