Machines that speak have been a common element in SpeculativeFiction almost since the beginning of the genre. Usually, such voices have been portrayed as either an electronic monotone, or as an endlessly calm human voice that, while certainly warmer than the electronic buzz of the synthesizer, is unsettling to listen to because of a lack of basic emotional content. This is because, for the most part, machines are incapable of actually feeling emotions.

When delivered in a flat monotone voice (that is usually free of contractions or slang), even SpockSpeak can take on creepy undertones.

This is especially evident when [[AIIsACrapshoot an artificial intelligence goes nuts]]. Despite going crazy and deciding to to KillAllHumans or simply to [[TheComputerIsYourFriend take over and rule us for our own good]], all the threats and casually vicious comments the machine makes are made in the same level, calm mode of talking, making them that much more creepy.

A subtrope of CreepyMonotone. Also a [[JustifiedTrope justification]] if the voice comes off as creepy.

This can be an aspect of the UncannyValley.

Compare SyntheticVoiceActor and ComputerVoice. Contrast ElectronicSpeechImpediment, where the lack of a Machine Monotone is a cause for concern.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* Father Tres Equis from ''LightNovel/TrinityBlood'', except he's a cold killer ''android''. He's still the kind of guy who proposes killing a small child for simplicity's sake, and lacks emotions of any kind. Probably one of the only example who actually acts as unemotional as a walking computer would. A few minor events suggest that Tres does some of this intentionally; he's certainly not as emotionless as people think.
%%* ''LightNovel/TheMelancholyOfHaruhiSuzumiya'': Yuki Nagato.
* The main antagonist of ''Anime/DigimonTamers'', the D-Reaper, also uses a Creepy Monotone (this time because it is evil/a computer program). This is made twelve times creepier because the CreepyMonotone it uses is the voice of Jeri, one of the main characters, whom it had absorbed early on.
* Project 2501 "the Puppetmaster" from ''Anime/GhostInTheShell'' speaks in monotone constantly, and for added dissonance, has a male voice in a female body, and does not move the mouth.
* Chachamaru in ''MahouSenseiNegima'' (played by Creator/AkenoWatanabe, who also plays [[WitchHunterRobin Robin Sena]]). This trait was carried over into the dub [[BritishStuffiness by giving her a British accent]], and casting Creator/CaitlinGlass to play her.
* The gynoid Dorothy from ''Anime/TheBigO'' speaks in a level electronic grate - although peculiarly, instead of making her seem detached or dispassionate, it transforms her into a snickeringly incisive DeadpanSnarker.
** The hero Roger has just literally kicked her into the middle of a crossfire - she emerges with her shell sootied, her clothes tattered, and her frazzled hair sticking out every which way. Her comment? "You're a louse, Roger Smith".
* ''Anime/{{Magical Girl Lyrical Nanoha The Movie 2nd As}}'' has [=NachtWal=], the [[ArtifactOfDoom The Book of Darkness]]' malfunctioning automatic defense system that speaks in GratuitousGerman with a calm, mechanical monotone [[spoiler:as it terminates the Wolkenritter, [[BreakTheCutie breaks Hayate's mind]], possesses her body, and starts destroying the world]].
[[/folder]]

[[folder:Film]]
* HAL 9000 of ''Film/TwoThousandOneASpaceOdyssey'' always talks in a near-monotone with just enough inflection to put it in the UncannyValley. Towards the end of the movie, when Dave is essentially lobotomizing him, HAL goes from trying to reason with Dave to pleading for his life, stopping only when he reverted to factory settings and began singing a rendition of "Daisy." All in the same calm, polite voice.
---> Dave: Open the pod bay doors, Hal.
---> HAL 9000: I'm afraid I can't do that, Dave.
* The original model ''Film/{{Terminator}}'' always spoke like this, even when mimicking someone else's voice. In the first sequel, it is revealed that the longer he spends in contact with humans, the more human he will come to act. But he still pretty much speaks in a flat monotone. The T-1000, on the other hand, is shown to be able to mimic vocal inflection, it just doesn't do it unless it's necessary.
* The agents from ''Film/TheMatrix'' all talk like this, even while in the midst of a gunfight.
* The Ilia-probe from ''Film/StarTrekTheMotionPicture'' spoke like this.
* Proteus IV in ''Literature/DemonSeed'', provided by an uncredited Robert Vaughn.
* VIKI from ''Film/IRobot'', in contrast to Sonny's speech, which is between this and a genuine emotional voice.
* ARIA in ''Film/EagleEye'', probably the best thing in all the movie.
* "Max", from ''Film/FlightOfTheNavigator''. At least, until it downloaded information from David's brain and accidentally took in some of his personality and started to sound like a sci-fi [[PaulReubens Pee-Wee Herman]]...
* EDI, the rogue plane of ''Film/{{Stealth}}'', is particularly cruel when says "Goodbye, Henry" to Jamie Foxx, one second before jamming him and his plane against a cliff.
* The titular MasterComputer from the 1970s film ''Film/ColossusTheForbinProject'':
-->''[[http://www.youtube.com/watch?v=-RdHuCyjqKw This is the voice of COLOSSUS...]]''
* The [=WOPR=] supercomputer ("Joshua") from ''{{Wargames}}''. Somewhat justified, because WOPR isn't really "talking", it's simply printing text which is run though a fairly simple text-to-speech synthesizer on the protagonist's home computer. That doesn't explain why SAC has the same text-to-speech conversion program for their war room, though.
-->"Shall we play a game?"
* GERTY from ''Film/{{Moon}}'' isn't monotone, but speaks in a rigidly pleasant and soothing tone.
* The calm monotone of David from ''Film/{{Prometheus}}'' just serves to make his semi-sarcastic one-liners all the more cutting.
[[/folder]]

[[folder:Literature]]
* [[AIIsACrapshoot AM]], the genocidal supercomputer in Creator/HarlanEllison's short story "Literature/IHaveNoMouthAndIMustScream", is explicitly described as being very polite when it delivers this charming message to its captive humans:
--> "HATE. LET ME TELL YOU HOW MUCH I'VE COME TO HATE YOU SINCE I BEGAN TO LIVE. THERE ARE 387.44 MILLION MILES OF PRINTED CIRCUITS IN WAFER THIN LAYERS THAT FILL MY COMPLEX. IF THE WORD HATE WAS ENGRAVED ON EACH NANOANGSTROM OF THOSE HUNDREDS OF MILLIONS OF MILES IT WOULD NOT EQUAL ONE ONE-BILLIONTH OF THE HATE I FEEL FOR HUMANS AT THIS MICRO-INSTANT FOR YOU. HATE. HATE."
** [[LargeHam The game on the other hand...]]
* The Toralii in ''Literature/{{Lacuna}}'' are physically unable to speak English and vice versa, so when they want to talk to the Humans they use a translator program that sounds like this.
* HEX, the University thinking machine in the ''{{Discworld}}'', ++talks like this++And his speeches follow this orthographic convention++This is based on early computer print-outs to indicate that he is printing his responses, rather than speaking them++However, when HEX gets an actual voice, he still uses (++) as punctuation to indicate a full stop++
[[/folder]]

[[folder:Live Action TV]]
* ''Series/DoctorWho'':
** In the episode "Robots of Death", the eponymous robots speak with no inflection. More of than than not, all the robots and computers tend to do this.
** The modern Cybermen, as well as their original incarnations from the '60s, speak in a constant and unchanging monotone. And that's the [[BodyHorror least freaky]] thing about them.
** The Daleks avert this. There are some instances where they talk in a rather monotone voice, but most of the time they simply shout in xenophobic rage.
* In Gene Roddenberry's failed pilot ''Questor'', the titular android (played by the always excellent Robert Foxworth) spoke like this.
* Cameron, from ''Series/TheSarahConnorChronicles'', uses a Machine Monotone in general. The absence of the MachineMonotone we're used to is what made the scene where she recites, not only word for word but inflection for inflection, a "classmate's" emotional bathroom rant for the principal creepy.
** Similarly, in the second season premiere, the steady shift from Cameron's Creepy Monotone to her desperate, terrified pleas to John to a screaming declaration that she ''loves'' him while he's trying to take out her chip makes for a chillingly awesome scene.
** And in the episode "Allison from Palmdale", the use of the Creepy Monotone and its absence makes an already chilling episode that much creepier.
* ''Series/TheBionicWoman'' (1970s) episode "Doomsday is Tomorrow". The [[strike:HAL 9000]] ALEX 7000 computer that's trying to kill Jaime has a voice like this.
* The androids in the ''Series/{{Star Trek|The Original Series}}'' episode "Mudd's Planet" all spoke in a constant monotone.
** Not to mention the main computer of Enterprise.
*** Except the one episode, when it gets reprogrammed with a husky female voice.
* ''Series/BuffyTheVampireSlayer'' has had at least two monotone androids:
** The first was the android "Ted". He keeps it up even with half his face missing during his fight with Buffy.
** The other was April, an android created by Warren Meers in a fifth-season episode. Xander and Anya even remark that her strangely even and polite monotone, while odd, is a turn on to some guys. Considering her original purpose in being built it was probably intentional.
** The Buffybot has an even "Creepy Perkiness" manner of speaking.
* Although they don't exactly sound like it, the Borg Collective in ''Series/StarTrekTheNextGeneration'' technically speaks in a monotone, albeit a [[VoiceOfTheLegion loud, reverberating]] one. Certainly, their insistence that everything you throw at them is "irrelevant" fits this trope to a T - and they have the ability to back it up. Locutus' speech patterns sound closer to a traditional Creepy Monotone, but he slipped some inflection in there amid the creepy disjointedness. The Borg Queen pretty much threw the whole idea out the window.
** Locutus (a hybrid of types 2 and 3) was specifically intended by the Borg to facilitate "relations" between themselves and the bothersome humans who kept resisting. His inflected speech and referring to Riker as "number one" were poor attempts to put the humans at ease, most likely. Of course, this was even ''more'' horrible than if he'd spoken like the other brain-dead, soulless drones.
* Vicki on ''SmallWonder'' is a comedic example, though she also did natural intonations from time to time.
[[/folder]]

[[folder:Music]]
* The song "Fitter Happier" by Music/{{Radiohead}} delivers this in the way [[SyntheticVoiceActor only a machine can]].
* "The Robots" by Music/{{Kraftwerk}} had this.
* Technical death metallers Music/TheFaceless use this to effect in their ''Planetary Duality'' album.
[[/folder]]

[[folder:Pinball]]
* ''[[Pinball/PinBot Pin*Bot]]'' delivers all of his lines in a robotic monotone.
** Played with in ''Pinball/TheMachineBrideOfPinbot''; while Pin*Bot himself still has his robotic monotone voice, the Bride speaks with a clear human voice.
** This scenario is repeated in the third game in the series, ''Pinball/JackBot''.
* The titular character from ''Pinball/BlackKnight'' speaks like this.
* Unintentionally done in ''Pinball/EightBallChamp'', as the voice clips that were ''meant'' to sound human ended up like this instead.
* Played with in ''Pinball/TheTwilightZone''; during the game, a robot warns, "Don't touch the door!" At the start of multiball, the same quote plays, getting higher and higher pitched every time.
* ''Pinball/{{Gorgar}}'' combines this with YouNoTakeCandle.
* Mission Control in ''Pinball/{{Flight 2000}}'' talks like this.
** Along with Mission Control in ''Pinball/SpaceShuttle''.
* The voice in ''Pinball/BlackHole'' also speaks like this.
* Done in Creator/{{Bally}}'s ''Pinball/{{Centaur}}'', usually to taunt the player.
-->'''Centaur:''' "Bad move, human."
* Used by the Devil in ''Pinball/DevilsDare'' to give game directions.
* One of the voices for Mission Control in ''VideoGame/ThreeDUltraPinball'' is a female monotone.
* Used in ''Pinball/{{Firepower}}'', Williams' second game with speech.
* ''Pinball/{{Spectrum}}'' combines this with VocalDissonance, giving the BaldWoman "Computor" a distinctly masculine voice.
* The KillerRobot of ''Pinball/{{Robot}}'' speaks in a distinctively digital monotonic voice.
* ''Pinball/{{Embryon}}'' speaks in a clinically monotonic male voice.
[[/folder]]

[[folder:Tabletop Games]]
* The ''TabletopGame/{{Paranoia}}'' rulebook advises the GM to use such a voice for The Computer (among a few other creepy options). Most of the time, The Computer is very polite - [[DissonantSerenity even when]] he's ordering a Troubleshooter to visit the nearest suicide booth or charge the Mutant Commie Traitor barricade [[WithThisHerring armed only with a can of Bouncy Bubble Beverage]]. To be fair, in that last case, [[MadeOfExplodium you aren't completely unarmed]].
[[/folder]]

[[folder:Video Games]]
* [=GLaDOS=] in ''VideoGame/{{Portal}}'' is a perfect example. "We hope your brief de-ten-tion in the Re-lax-a-tion Vault has been a plea-sant one." Though in the case of [=GLaDOS=], the even worse problems start when the monotone breaks. Then she starts ''giggling''.
** The shit ''really'' hits the fan when the monotone starts up again.
---> ''"Good news. I figured out what that thing you just incinerated did. It was a [[MoralityChip morality core]] they installed after I flooded the Enrichment Center with a deadly neuro''tox''in to make me stop flooding the Enrichment Center with a deadly neuro''tox''in. So get comfortable while I warm up the neurotoxin emitters..."''
*** This is all the more unnerving as her previously clinical monotone shifts to a more organic (some might even say ''sultry'') monotone.
** [=GLaDOS=] isn't monotonous for much of the time. Her pitch changes regularly, almost every syllable in fact. What makes her sound disturbing is that every syllable is spoken inhumanly flat and detached, and they do not flow into one another.
*** This is because her speech patterns were done by running the lines through Text To Speech software, then having the voice actress model her delivery on that (with a dash of emotion for flavor)
** Not only that, but her voice changes comparing to what's happening to her. In the beginning she sounds like a hyperadvanced Microsoft Sam, then when you escape her [[spoiler:deathtrap]] her voice, and reasoning, becomes more disjointed, and when you destroy her morality core her voice becomes less Microsoft Sam-ish, but more smooth and... one might even say sexy, were it not that [[spoiler:she hates your guts and wants to murder you real bad]].
** Subverted in ''Portal 2'' during her VillainousBreakdown just before [[spoiler: the core transfer takes place]]. For the rest of the game, she alternates between her "normal" monotone and actually showing some emotion; it's actually pretty amusing hearing [=GLaDOS=] freak out during the Aperture Science bits.
* The Combine Overwatch from ''VideoGame/HalfLife2'' is another example; "she" may be an AI, although it is more likely she is just the alien equivalent of a tech support answering machine.
** Who ends up [[http://www.youtube.com/watch?v=KvYGSL0uZok sounding more like]] [=GLaDOS=] for [=HL2=] Episode Two.
*** Because it's the same voice actress.
** Doubly creepy because the Overwatch Dispatcher refers to Overwatch assets and objectives with mostly medically-inspired jargon: turrets are "sterilizers", soldiers are "protection teams", and the order to isolate and kill intruders is "Clamp. Expunge. Sterilize."
** ''VideoGame/HalfLife'' has a similar PA system in Black Mesa (usually given the name VOX to distinguish it from the PA system heard during the tram ride). It was probably meant to be a text-to-speech system, but probably due to technical reasons, the game splices together a dictionary of pre-recorded words, similar to how ''VideoGame/OperationFlashpoint'' worked.
* ''VideoGame/SystemShock'' completely averts the trope with SHODAN, who is scarily passionate for an AI at times, especially when something doesn't work out like it should -- or when it does.
** XERXES in part 2 plays it straight, however. Turns into ''CreepyMonotone'' once he starts spouting stuff like "Glory to the flesh. Glory to [[TheVirus the Many]]."
* ''VideoGame/DeusEx'' uses this trope to its full extent, partly because it used so many famous examples as inspiration, such as SHODAN, HAL, Agent Smith and Project 2501.
---> '''Icarus:''' ''(calmly)'' Your systems were very cooperative. Upload complete.
** Daedalus speaks in a monotone because he uses a voice-filter to avoid anyone detecting that he is, in fact, an AI and not just a rather well written interactive operating system. Icarus doesn't speak in a monotone, but every single sentence is pure hate run through a voice synthesizer, and includes such gems as the above while presumably [[MindRape installing a rootkit your brain]]. Helios uses the the more HAL-esque flat voice, coupled with irregular voice patterns.
* KOS-MOS in Xenosaga speaks monotone, although her evil counterpart [[AIIsACrapShoot TELOS]] speaks normally in Xenosaga III
* In ''VideoGame/{{Persona 3}}'', when SEES first comes across [[RobotGirl Aigis]], she speaks in a very dull monotone. Throughout the game, though, as she learns more about what it means to be a human being, she gradually starts to speak more fluidly and naturally: by the time she re-appears in ''Persona4Arena'', her speech, while still slightly stilted, sounds very human-like. Her "sister unit", Labrys, averts this trope completely, speaking very fluidly (albeit with a thick [[KansaiRegionalDialect Kansai]]/[[BrooklynRage Brooklyn]] accent).
* ''Franchise/{{Halo}}'': "This is UNSC AI Serial Number CTN-4169. I am a monument to all your sins."
* HK-50/47 from both ''KnightsOfTheOldRepublic'' games. "Mocking Query: Coorta? Coorta? Are you dead yet?"
** Actually, only the prefixes seemed to be delivered in monotone. The rest was no different from any other speaking droid in ''StarWars'', especially HK-47's clearly audible annoyance at not being allowed to shoot everything in sight and having to use that disgusting word "master".
* Played with in the ''Franchise/MassEffect'' series with the synthetic characters.
** [[http://www.youtube.com/watch?v=QNjLnnjguQk Legion]] in ''VideoGame/MassEffect2'' is probably the straightest example, and even then it is subverted on several occasions as the character shows some very organic-like quirks and attachments, and its voice reflects that.
** The voice of [[http://www.youtube.com/watch?v=-iZyPamkEUs Sovereign]] in the first game is also somewhat monotone, but it's not a "flat", emotionless monotone, but a menacing one. The [[http://www.youtube.com/watch?v=RhUM8v3dD3I Reaper destroyer]] in ''VideoGame/MassEffect3'' also speaks with a similar tone.
** Averted with other synthetic characters, most notably EDI, who can be playful, humorous, or even caring (though still with a little touch of deadpan), and Harbinger, who is a LargeHam.
* ''VideoGame/BlazBlue'''s RobotGirl Nu-13 speaks in a creepy monotone, [[{{Yandere}} except around Ragna.]] And in Noel's ending [[spoiler:Noel loses her identity, and begins speaking in the same monotone.]]
* The voice on the intercom in the third ''VideoGame/{{Penumbra}}'' sounds like this. At first, it seems like a typical automated announcement device, but it turns out to have an awareness and personality. However, the usual characterization is subverted--it's not evil, and judging by its words it can feel horror and loneliness.
* Megaman Juno in ''VideoGame/MegamanLegends'' speaks in a very polite, almost whispering voice about wiping out an entire civilization with a satellite strike. It's also worth noting that he initiates these cataclysmic events with a warm and friendly [[AffablyEvil smile]] on his face.
* The arcade game ''{{Berzerk}}'' may be the UrExample in video games. Not technically a ''mono''tone since there were at least two distinct pitches, though each line only used one of the two. The clearest example was after the player died:
-->'''Lower pitch:''' Got the humanoid
-->'''Higher pitch:''' Got the intruder
* In ''VideoGame/AssassinsCreedBrotherhood'', findings voids in the Animus' software will drop you into a set of puzzles narrated by an emotionless female voice...which becomes extra creepy when the voice begins to speak as though it's lost and alone, wandering through endless darkness. [[spoiler: This is because Subject 16 can only speak in a machine voice once he's [[BrainUploading uploaded]] ''himself'' [[MindScrew into the Animus]] (until he loads his real one).]]
* ''VideoGame/{{Homeworld}}'' has Fleet Command. Even when [[spoiler:[[http://www.youtube.com/watch?v=ChRWSpodc3A their entire homeworld is annihilated]]]], half-human, half-machine Fleet Command still maintains her composed speech.
** Although the slight inflection of surprise in her voice when the first attackers arrive is obviously intended to show that there's still a person behind the voice.
* If you equip the Soldier with the Tin Soldier set (a cardboard box mask, shoes, and pair of ventilation pipes) during certain times of the year in ''VideoGame/TeamFortress2'', all of his combat voices will be replaced with robot-themed voices delivered in this fashion.
** Taken to its logical conclusion [[http://www.youtube.com/watch?v=gtzVlhic43Y when these lines are said by his robot self.]]
* Monita, TheHost of ''VideoGame/NintendoLand'', speaks like this.
* Out of all the robots in ''VideoGame/{{Primordia}}'', only [[TheDragon Scraper]] '''[[BoldInflation talks like this]]'''.
* Midway's ''VideoGame/{{Gorf}}'' and ''VideoGame/WizardOfWor'' are two other early "talking" video games, which also have a machine monotone (in fact, they both feature the exact same one).
* ''[[VideoGame/XCOMEnemyUnknown XCOM: Enemy Within]]'': The MEC troopers are soldiers who sacrificed their limbs for Meld-powered ones, so they can safely pilot giant [[PoweredArmor suits of power armor]] in combat. While the in-game descriptions state that the MEC troopers have amputated their limbs, their CreepyMonotone voices and [[RoboSpeak strangely formal speech patterns]] make you wonder if they sacrificed [[CyberneticsEatYourSoul more than just their arms and legs.]]
* The robots in the ''VideoGame/{{Fallout}}'' series, especially the Sentry Bots.
[[/folder]]

[[folder:Webcomics]]
%%* ''Webcomic/{{xkcd}}'' shows us [[http://xkcd.com/375/ what happens when two of these team up]].
%%* ''WebComic/SkinHorse'': "Greetings. We are here to destroy you. First, may we destroy you a beverage of some sort?"
[[/folder]]

[[folder:Web Original]]
* [[http://www.youtube.com/watch?v=G-z2xREDYkk This]] is a combination of this trope and AIIsACrapshoot.
* In ''Literature/{{Worm}}'', the supervillain Bakuda has a gas mask that does this to her voice.
* ''WebVideo/DragonBallAbridged'' gives KillerRobot Android 19 one of these by having a computer text-to-speech program voice him.
* [[ArtificialIntelligence Eudocia]] from ''Literature/{{Brennus}}'' speaks like this. However, [[GadgeteerGenius Polymnia]] manages to avert it despite using a voice synthesizer -- she custom-built her own, using her enhanced knowledge of sonics to make it sound very close to a real human voice.
[[/folder]]

[[folder:Western Animation]]
* Auto the autopilot from ''WesternAnimation/{{WALL-E}}'', itself a [[LampshadeHanging lampshade]] of HAL-9000.
* Parodied in ''WesternAnimation/{{Futurama}}'' where a HAL 9000-like spaceship talks like HAL at first until they change the voice to a cheerful girl's voice. It's still creepy when he/she/it becomes obsessed with Bender.
** Another episode features a rather fearsome robot nanny that shouts in a seemingly angry monotone, "Sleep, little dumpling! I have replaced your mother!" Leela says, "Aww!"
* Series: ''WesternAnimation/TheTransformers''. Example: Soundwave. Behavior: Always uses monotone. HAL 9000 voice synthesizer: Comparatively flexible. Outcome: [[EnsembleDarkhorse Enduring fame and popularity]].
** Soundwave of ''TransformersCybertron'' rocks the monotone too, but he remixes it with some phat JiveTurkey.
*** It is illogical to ignore Soundwave of ''[[TransformersAnimated Animated]].'' He speaks in complete sentences. This differentiates him from the original. His inflection remains flat and heavily synthesized. His sentences are clipped and precise. His voice remains a tinny monotone under all circumstances. He is Soundwave.
** There's also ''Animated'' Perceptor, who according to WordOfGod supposedly removed his personality to have more room for information storage. And he's one of the good guys. In fact, his synthesized voice is basically the same as StephenHawking.
** Omega Supreme talks like this because he was attacked by a MirrorMoralityMachine long ago. He was able to break free before it had finished reprogramming him, but it left him nearly emotionless. He ''can'' talk "like a normal Autobot," but it seems to take some effort. Prime expresses the hope that Omega may eventually recover his ability to feel, and Omega answers, "Possibility: growing."
** Subverted by Deceptitran (in the episode "Sea Change"), a Decepticon computer that is expressly ''proven'' to be nonsentient, but whose voice sounds like it's on the verge of hysteria.
** The Autobots' computers Teletraan-1 and Teletraan-2 both have fairly inflectionless voices, although 1 always sounds like it's boldly announcing something, and 2 has a more soothing HAL-type voice.
** The Decepticon Shockwave is described as an evil version of [[StarTrek Mr. Spock]], though that mostly refers to the comic-book version, who is every bit as fond of the word 'logic' as the Vulcans. However, he does speak in a very emotionless manner, with a bit of rasp as well. The ''Animated'' version talks the same way, and has the same actor, but [[spoiler: in his disguise as Longarm]], he talks much more normally and even has a different accent.
* The {{DCAU}} version of Brainiac, being an AI, is portrayed quite like HAL.
** Voiced by Creator/CoreyBurton, who also voices both versions of Shockwave.
* The computer from ''TheBraveLittleToaster''.
* Ultron from ''WesternAnimation/AvengersEarthsMightiestHeroes'' does this. As arrogant and psychotic as a machine he can get, his voice never really changes.
* The computer whom the Blockheads consult numerous times in the first movie of ''WesternAnimation/{{Gumby}}''. Midway, it starts changing tones for no apparent reason.
[[/folder]]

[[folder:Real Life]]
* Watson, IBM's Jeopardy playing computer, pretty much sounded like this.
* Who could forget {{Microsoft}} [[SyntheticVoiceActor Sam?]]
* StephenHawking. His is an interesting case, in that the synthesiser he uses is over thirty years old and significantly out of date, yet he continues to use it ''because'' the synthesiser's monotone is so universally associated with him and is, in effect, his actual voice as far as most everyone is concerned.
* The hacktivist group Anonymous use voice synthesizers to hide their identities.
