* In ''Film/BatmanVSupermanDawnOfJustice'', Batman uses an electronic voice modulator to alter his voice.

* Parodied in ''Film/SpidermanHomecoming'', where Peter Parker's suit (also made by Stark)'s "Enhanced Interrogation Mode" gives his voice a comically deep filter.
* Senator Palpatine/Darth Sidious in ''Franchise/StarWars''. Palpatine loses the "normal" voice entirely after Mace Windu's attack, when he becomes Emperor.

* [[Series/{{Arrow}} Oliver Queen, Sara Lance]] [[Series/TheFlash2014 and Barry Allen]] all make use of voice modulators in their superhero guises. [[EvilCounterpart The Reverse Flash and Zoom]] both sound noticeably deeper when in costume as well.

* ''Videogame/BlazBlue'': Hakumen wears a full-body armor and a deep, echoing voice courtesy of the armor. His voice is actually much softer, courtesy of him being [[spoiler:an alternate timeline Jin Kisaragi.]]
* 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]].
* The [[VideoGame/BatmanArkhamKnight Arkham Knight]] uses an electronic voice modulator to distort his normal voice. [[spoiler:Given that Batman would recognize Jason's voice otherwise]], it does its job well.

* While less drastic than in the Nolan films, in ''WesternAnimation/BatmanTheAnimatedSeries'', Batman has a lower voice than Bruce Wayne.

* Just like the original Batman, in ''WesternAnimation/BatmanBeyond'' Terry's voice also changes in when he's in the bat-suit, though it's explained to be something the suit actually does somehow to help disguise his identity.
* Unlike ''BTAS'', ''WesternAnimation/TheNewBatmanAdventures'' and following DCAU entries avert this, with Batman and Bruce Wayne having the same voice.
* Also from DCAU, the Batwoman in ''WesternAnimation/BatmanMysteryOfTheBatwoman'' has a voice unlike her real identity ([[spoiler:that is, any one of the three]]). This overlaps with CastAsAMask as the Batwoman has a voice actress that doesn't voice any of the other characters.
* Parodied by Buttercup/"Mange" in ''WesternAnimation/ThePowerpuffGirls'' episode where they decide that they all need secret identities to be "real" superheroes.

This distinct from the more appearance-oriented ClarkKenting. This is an effective way to maintain a SecretIdentity and it can also suggest a case of SecretIdentityIdentity if you consider that the person's two identities have totally different voices and mannerisms.

* In ''Film/OnHerMajestysSecretService'', in the scenes where Bond is impersonating an expert on heraldry GeorgeLazenby is dubbed by the actor who played the real expert.

* In ''WesternAnimation/SouthPark'', [[spoiler: Kenny]] does this when dressed as Mysterion.

* ''Series/HunterStreet'': When disguised as [=HoodieHead=], [[spoiler: Sophie has a vocal modulator to change her voice to be unrecognizable.]]

* 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]].
* The [[VideoGame/BatmanArkhamKnight Arkham Knight]] uses an electronic voice modulator to distort his normal voice. [[spoiler: Given that Batman would recognize Jason's voice otherwise]], it does it's job well.

* 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]]

* Series/HunterStreet: When disguised as [=HoodieHead=], [[spoiler: Sophie has a vocal modulator to change her voice to be unrecognizable.]]

A character changes voice while in costume. It is usually an attempt to disguise themselves.

This distinct from the more appearance-oriented ClarkKenting . This is an effective way to maintain a SecretIdentity and it can also suggest a case of SecretIdentity if you consider that the person's two identities have totally different voices and mannerisms.

* Also from DCAU, the Batwoman in ''WesternAnimation/BatmanMysteryOfTheBatwoman'' has a voice unlike her real identity ([[spoiler:that is, any one of the three]]), though this overlaps with CastAsAMask.

Examples:

* The UrExample is probably the 1940s RadioDrama ''Radio/TheAdventuresOfSuperman'', in which voice actor Bud Collyer shifted his speech down an octave each time he switched from Clark Kent to the costumed hero. (This carried over to his later work in Superman cartoons, as previously mentioned.)

* 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 ChineseElectricBatman]]

Unlike ''BTAS'', ''WesternAnimation/TheNewBatmanAdventures'' and following DCAU entries avert this, with Batman and Bruce Wayne having the same voice.

UpForGrabs. Think this is distinct from the more appearance-oriented ClarkKenting (also thought it would be good to have something to cover the non-evil instances of EvilSoundsDeep). This is an effective way to maintain a SecretIdentity and it can also suggest a case of SecretIdentity if you consider that the person's two identities have totally different voices and mannerisms.
