Alice is talking to a stranger on the bus, when she realizes that she's heard his voice before, somewhere. Moments later, Alice realizes she's talking to Bob, her {{Mentor|s}} whom she hasn't seen in 15 years. Bob may or may not realize who Alice is.

In short, this is when a familiar voice reveals the identity of a character in a moment that is shocking to the audience and/or other character(s).

* Late in ''Manga/{{Monster}}'': Eva Heinemann realizes that [[spoiler:her lawyer's partner is in fact "Roberto", a former hit man working for Johann who'd been her lover before trying to kill her]]. She'd spoken to him over the phone once or twice, but when she heard his voice in person, it hit her like a ton of bricks.
* The reveal of the final villain in ''Anime/{{Digimon Adventure 02}}'' [[spoiler: Myotismon]] has this effect in the English dub; his laugh for [[spoiler: Gatomon]] and his voice for audiences who saw the first season and would recognize it.

[[folder:Audio Play]]
* ''AudioPlay/BigFinishDoctorWho'' does this rather a lot, especially for TomatoSurprise reasons:
** In "Jubilee", a pair of interrogators are torturing a creature in the Tower of London, and it refuses to talk. The torturers beg it to 'speak', but it doesn't make a sound (only, eventually, a scream). We only hear it talking when the Doctor goes in to communicate with it and it suddenly shouts, "[[foldercontrol]]

[[folder: [[Robo Speak The Doctor is an enemy of the Daleks. He must be exterminated. ]]
** "The Holy Terror" concerns a [[GooGooGodlike child god]] with a face that the one-shot companion, Eugene, claims to have seen before. In order to determine who the child is, the Doctor asks it to talk in a lower voice 'like adults do'. As its voice decreases in pitch and ages we realise it's the voice of Eugene.
* Two of the lead characters in The Dolls of New Albion" have a moment like this when [[spoiler: John O'Brien]] recognizes [[spoiler: Constance]] as his daughter and sings to her an old lullaby he had sang when she was a child, thus jogging her memory.

[[folder: Comic Books]]
* In the ''Franchise/{{Tintin}}'' book ''Recap/TintinLandOfBlackGold'', Tintin wonders about the saboteur leader's voice. It turns out to be Dr. J.W. Muller from ''Recap/TintinTheBlackIsland''.

* ''Film/DeathAndTheMaiden'': When Paulina Escobar hears Doctor Miranda speak and laugh, she recognizes his voice as that of the man who was in charge of her torture and rape by government thugs years earlier.
* ''Film/CollateralDamage'' had a bad guy identified that way.
* ''Film/WhoFramedRogerRabbit'': "Remember ME EDDIE? When I killed your brother, I TALKED JUST ''LIKE'' '''THIS!!!'''"
* Tom realizes that Shaker was his son's kidnapper in ''Film/{{Ransom}}'' when he sees his son Sean's [[BringMyBrownPants reaction]] to his voice.
* In ''Film/TheCrow'', Brandon Lee's rock artist Eric was good friends with a young girl before his murder. Upon returning as a super-powered revenant based on vengeance, he winds up meeting the girl again. He speaks to her a bit then quotes one of his songs, at which point he escapes into the night and she loses sight of him. The girl calls out, "Eric?"

* In ''Literature/{{Discworld}}'', many people die and don't realize that they're dead until they hear the distinctive voice of fan-favorite [[/folder]]

[[folder: Death ]]
, who always [[/folder]]

[[folder: talks like this. ]]

** Works on the readers, too. Sometimes, Death will just show up and say a line or two without ever being explicitly identified to anyone but the reader via the dialogue.
** In ''Discworld/TheTruth'', William discovers the identity of the mastermind ([[spoiler:his father]]) not by his voice but by his favorite quote which he gives out ad nauseam captured on a recording device.

[[folder:Live-Action TV]]
* "The Man" on ''Series/{{Alias}}''
* On an episode of ''Series/BurnNotice'', Season 2 ("Bad Breaks"), Michael is unexpectedly stuck in a bank in the middle of a robbery. He pretends to be a doctor, which gives him various opportunities to cause trouble for the bad guys. After many fun shenanigans, Sam ends up calling the head bank robber on his cell phone, pretending to be a powerful, scary guy who "really owns the bank". Michael confirms that he "recognizes the voice", and relates a story about what a powerful, scary guy Sam is, which causes dissension in the ranks of the remaining robbers.
* On ''Series/{{Smallville}}'', Clark occasionally phoned Lois as "The Red and Blue Blur" using a voice modulator to disguise his voice. One time (when we discover that Chloe has a tap on his phone, and on all the other phones in the world) some Meddling Kids mess with Chloe's setup, rendering Clark's modulation ineffective, and she heard his real voice.
* Twice on ''Series/TheMuppetShow'' a mysterious character appears with a mask - a black knight in one episode, a [[Film/StarWars Darth Vader]] parody on another. But when the character speaks, it is clear by his distictive voice that it's Gonzo. That and [[GagNose the nose]].
* An episode of ''Series/MarriedWithChildren'' has the NO MA'AM men horrified beyond belief when Peggy's horrifically obese mother demonstrates that she is the voice behind "Butter", the phone sex girl they'd been talking to.
* ''Series/DoctorWho'':
** Variation: In the story "The Macra Terror", Ben seems to have been {{Brainwashed}}, but we don't realise for sure until his usual Cockney accent suddenly changes mid-sentence to the RP one used by the CompellingVoice.
** "[[Recap/DoctorWhoS27E6Dalek Dalek]]", an adaptation of the audio play ''Jubilee'' (listed above), steals the introduction of the titular monster. It works even better on camera due to [[TalkingLightbulb the way that Daleks emote]].
** "The Stolen Earth" reveals its iconic monster in the same way. [[spoiler:For the same reason.]] In this case, the message is broadcast worldwide, with a who's-who of previous companions [[MassOhCrap reacting in horror.]]
** In "Day of the Doctor", the Doctor is babbling to himself about how he could curate an art gallery, and he could retire and do that. Then someone interrupts him by saying "I really think you might", in the unusual, distinctive voice of [[spoiler: the Fourth Doctor]], immediately leaving him dumbstruck.
* Happens in ''Series/{{Elementary}}'' when Kitty Winter hears the voice of [[spoiler:Del Gruner, Watson's new boss]]--and realizes that's he's the SerialKiller and rapist who victimized her (and many other women, none of whom survived).
* Likewise in the ''Series/TheEqualizer'', a blind woman steps into an elevator holding several other people and recognizes the voice of the man who raped and blinded her years before. She hires [=McCall=] to establish who else was in the elevator at the time.
* Averted in ''Series/{{Cracker}}''. A woman who was blindfolded and raped is later picked up at her house by a taxi driver who's actually the rapist. She recognises his voice, but thinks it's just a traumatic response causing her to see her rapist in every man she meets.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'' adventure "Night of the Vampire": When Lady Constantina is impersonated by her maid, the players can recognize this by the difference in their voices on the audio CD track.

* A theatrical adaptation of the book ''Coram Boy'' did a chilling version of this; [[spoiler: Meshak's father, a man with a distinct Cockney accent, was introduced in the first act as a man who extorted money from poverty-stricken mothers in exchange for taking their children to the Coram Hospital, only to murder and bury them with the unwilling help of his mentally-disabled son Meshak, for which he is apparently hanged. The second act introduces a man who speaks with an upper-class accent involved in selling educated and virginal Coram girls into sexual slavery]]. Eventually, Meshak meets the second man face-to-face, and hearing his sudden shift into the first man's voice is genuinely shocking, especially given his activities. It works particularly well as a play, since the audience's distance from the actors allows the man's face to go unrecognised more effectively than could be easily accomplished on film.

[[folder:Video Games]]
* ''VideoGame/AlanWake'' has a scene where this is part of how Alan identifies a man who had called him earlier. [[spoiler: The kidnapper]]'s voice was pretty distinct, but there were other clues Alan noticed as well.
* In ''VideoGame/BatmanArkhamOrigins'' we think that all that is going on is because of Black Mask, that is until we see the man who is supposed to be Black Mask on the ground being slapped and beaten by the guy posing as him.
-->[[spoiler:Joker]]: Can't... You... Just... Play... '''ALONG?'''
* The big reveal of Chaptain Schwann's identity in ''VideoGame/TalesOfVesperia'' comes when you hear him speak for the first time, [[spoiler: and his voice is unmistakably that of Raven, one of your party members.]] As stated on the WhamLine page, the line is a Wham not for the line itself, but the voice it's said in.
* ''VideoGame/TalesOfXillia2'' has an interesting inversion. One of the main reasons the protagonist, Ludger, is a HeroicMime is to avoid giving away that he shares a voice with [[spoiler: Victor, one of the game's major antagonists. Victor turns out to be his [[AlternateSelf alternate-universe counterpart]].]]

[[folder:Visual Novels]]
* In ''VisualNovel/PhoenixWrightAceAttorney'', [[spoiler: Manfred von Karma]] is ultimately confirmed as the killer of [[spoiler: the DL-6 Incident]] this way. After Phoenix reveals that he can prove that [[spoiler: the bullet in von Karma's shoulder comes from the same gun that killed Gregory Edgeworth, von Karma]] lets out a scream -- that Miles Edgeworth recognizes as the same one he heard [[spoiler: when his father was shot]].

* ''WebVideo/AtopTheFourthWall'':
** At the end of the review for ''ComicBook/{{Youngblood}}'' #4, Linkara and Harvey Finevoice have cornered the villain possessing the sinister new body for Pollo, [[spoiler: whom they believe to be Mechakara, only for it to speak in a ''different'' familiar voice.]]
-->[[spoiler:'''Lord Vyce:''' [[EvilSoundsDeep That is not my name.]]]]
** At the end of the review for ''ComicBook/{{Ultimate|Marvel}} [[ComicBook/SupremePower Power]]'' #4, Linkara is yelling at Erin; at the moment he says [[spoiler: "Human", his voice changes into the Entity's.]]
-->[[spoiler:'''The Entity, possessing Linkara:''' [[WhamLine No,]] [[VerbalTic human]], [[HesBack this]] ''[[DemonicPossession is]]'' [[TomatoSurprise a]] [[FromBadToWorse game]] -- [[SuddenlyShouting and it's one I intend to win!]]]]

[[folder:Western Animation]]
* ''WesternAnimation/TotallySpies'' episode "Miss Spirit Fingers (Jazz Hands' Return - Part 2)": While Alex and Clover are eavesdropping on a conversation between the villain Jazz Hands and Miss Spirit Fingers, they notice that Miss Fingers has the same voice as Sam. They realize that Sam is masquerading as Miss Spirit Fingers and (wrongly) conclude that Sam has defected and joined Jazz Hands.
* A RunningGag on ''WesternAnimation/RockyAndBullwinkle'' is that whenever they meet Boris in disguise, Rocky always asks "That voice! Where have I heard it before?" In one episode, Bullwinkle answers, "In about 365 other episodes, but I don't know who it is either."
* In ''WesternAnimation/BarbieSpySquad'', Barbie and Teresa are flabbergasted when the apparently American Auntie Zoe reveals herself to be a British secret agent.

[[folder:Real Life]]
* Notorious spy Robert Hanssen was finally caught when the FBI, which had focused in on a different person as the suspect, obtained a voice recording of the spy and the agent who listened to the tape recognized Hanssen's voice (granted that his voice was only recognized after [[SomethingOnlyTheyWouldSay someone recognized a racial slur he had made]]).
