Writing a movie? Need a mechanical-sounding voice for your robot? Voice actors are so ''difficult''. What if there was something easier?

A Synthetic Voice Actor (or a [[JustForPun synthespian]]) is a synthetic voice program that voices a character. It's not used a lot, especially when union rules would make that difficult. It's usually used for extremely robotic voices, or a CaptainErsatz of Creator/StephenHawking. It more commonly springs up in AbridgedSeries and {{machinima}}, partly to get extra voices, and partly because of RuleOfFunny. When used against human actors, it tends to make the speaker seem inhuman -- in more serious works, it's used for threatening robotic characters, usually. Compare the computer voice on the ''[[Franchise/StarTrek Enterprise]]'' (real person) to [[WesternAnimation/WallE AUTO]] (not a real person).

This trope may not apply to [[http://www.cepstral.com/ Cepstral voices]], or to programs like Voicestitcher (thevoiceplanet.com is down indefinitely).

[[folder: Anime ]]

* The episode title announcer in ''Anime/SerialExperimentsLain'' was a [[AppleMacintosh Macintosh]] program named [=PlainTalk=] (often falsely called "Whisperer" because of its "Whisper" voice mode).


[[folder: Film ]]

* They planned to do this to make the Voice of God in ''WesternAnimation/ThePrinceOfEgypt'', but after discovering a lot of really good demonic voices they just [[TalkingToHimself used Val Kilmer for both Moses and God]].
* ''Film/BackToTheFuturePartII'' used Creative's [=TextAssist=] for the voice of the self-drying jacket and the future [=McFly=]'s house.
* ''Film/ShortCircuit'' likewise used [=TextAssist=] for the voice of the robots, ''except'' for Johnny 5, who was dubbed by a voice actor to show that he really had emotions.
* ''Film/BillAndTedsBogusJourney'' used the UsefulNotes/{{Amiga}} speech synthesizer for the voices of the good Bill and Ted robots.


[[folder: Live Action TV ]]

* The Cylons in the 1978 original ''Series/{{Battlestar Galactica|1978}}'' series spoke this way (human actors run through a synthesizer).
* ''Series/DoctorWho'': Averted in all instances.
** Creator/TheBBC originally considered doing this for the Daleks, but with 1963 technology, they could have done only 45 seconds of dialogue this way, so they used a human voices filtered through a ring modulator. It's actually pretty easy to duplicate the Dalek voices. Record your voice with Dalek speech-patterns, [[LoudnessWar over-amplify]] it to add clipping distortions (this step is the one people often forget or don't know about, including, occasionally, the actual BBC effects people), then run the results through a ring modulator plugin using 20-40Hz for the frequency of the modulation.
** The initial creepy [[AccentOnTheWrongSyllable sing-song voice]] of the Cybermen in "The Tenth Planet" was created by (human) voice actors imitating the glitchy speech cadences of the first ever 'singing' computer, IBM 704. The BBC did the Cyberman voices for most of the 1960s by having a human actor use an electrolarynx (an artificial throat-vibrating device for people who had lost their larynx to cancer or injury - they're rarely heard nowadays, but a prominent fictional user is Ned in ''WesternAnimation/SouthPark''). The 2009 revival version of the Cybermen simply had an actor's voice run through a ring modulator with a different setting to what was used for the Daleks.
** The Daleks, also, do not have mechanical voices, only voices that ''sound'' mechanical. A truly mechanical voice would probably be one-note-just-like-this, but Daleks have a cadence to their voices, and they also go "EX-TER-MI-NATE! EX-TER-MI-''NAAAAATE!''" with each intonation rising in pitch and volume. They look like tin cans, but they have some powerful emotion inside them.
* The person with [[AndIMustScream Locked-In Syndrome]] in ''Series/{{Scrubs}}'', too.


[[folder: Music ]]

* The Music/{{Radiohead}} song "Fitter Happier" is "sung" by Mac [=PlainTalk=].
* Ken Leavitt-Lawrence, better known as MC Hawking, who uses a text-to-speech program to do parody-gangster rap under the guise of Stephen Hawking himself.
* Music/{{Kraftwerk}} may have been the pioneers of using this trope in music.
* Music/{{Erasure}}'s cover of "Video Killed The Radio Star" was "sung" by the keyboardist's laptop, since the human singer refused to sing it.
* The entire point of the Music/{{Vocaloid}} series. Though they still have a human voice source.
** Played straight with Defoko, the default voice of the similar program [=UTAU=], who is sourced from a program called [=AquesTalk=].
* Apoptygma Berzerk's Kathy's Song has the chorus sung by the Mac text-to-speech Kathy voice. Of course, the song is essentially an [[RoboSexual exchange between the singer and his computer]]. It's awesome.
* [[IAmSong My. Name. Is.]] Music/{{Skrillex}}.
* Music/CamperVanBeethoven's version of "Sisters Of The Moon" by Music/FleetwoodMac has a text-to-speech program reciting the lyrics (and also throwing in seemingly arbitrary quotes from Pindar, Creator/WilliamShakespeare, and ''Film/ThisIsSpinalTap''). As with Erasure's "Video Killed The Radio Star" cover, this was done because no one in the band wanted to sing it.
* The voice of the fictional singer Lumi of the Genki Rockets is thought to be either synthesized or a composite of Rachel Rhodes and Nami Miyahara.
* Elise's singing voice in Music/SoundHorizon's "Märchen" was created using the Hatsune Miku Music/{{Vocaloid}} software, with Revo's reasoning being that it made sense for a CreepyDoll to have an artificial voice. Her speaking voice, on the other hand, is provided by Fujita Saki (aka, the original source for Miku's voice).
* Assemblage 23's "Automaton" uses a vocoder (which he rarely uses) to complement [[CyberneticsEatYourSoul the song's subject]].
* Mind.in.a.box's "Change", "8 Bits", "I Love 64" and "Unknown" have heavily processed vocals to emulate this effect, though the actual singer is human (he can be heard singing normally on "Remember" and towards the end of one of the "8 Bits" remixes).
* Music/{{Beck}}'s [[http://youtu.be/qGUPXKG935c "Ghettochip Malfunction (Hell Yes)"]] has a deep synthetic voice echoing some of the lyrics.
* Overlaps with CelebrityVoiceActor: Stephen Hawking lent his voice to "Keep Talking" on Music/PinkFloyd's "The Division Bell."
--> It doesn't have to be like this. All we need to do is make sure we keep talking.
* [[http://www.farcethemusic.com/2013/12/cruise-parody-booze.html This]] parody of "Cruise" by Music/FloridaGeorgiaLine was done using the scorewriter programs Melody Assistant and Virtual Singer, the latter of which is ExactlyWhatItSaysOnTheTin.
* Speaking of bro-country, a synthesized voice (either Microsoft Sam or a soundalike) recites a TitleDrop at the beginning of Chase Rice's "Ready Set Roll".
* The ''[=HMKids=]'' song "[[TabletopGame/{{Warhammer 40000}} Adeptus Mechanicus]]" is a [[MachineWorship Machine-Cult prayer]] recited by a Text-To-Speech program, accompanied by [[OminousPipeOrgan pipe organs]], drums, and electric guitar.
* The {{Eurobeat}} artist April, of [[https://www.youtube.com/watch?v=v4t6WOW5kII "Hanami"]] and [[https://www.youtube.com/watch?v=6BQmxMf7Py8 "The Magic I Feel"]], appears to be a completely synthetic voice.
* The Plogue virtual instrument plugin Music/{{chipspeech}} contains a bank of recordings of various ancient speech synthesisers, which can be played via a keyboard like a musical instrument. Each voice is assigned a Music/{{VOCALOID}}-esque character:
** Dandy 704, a rogueish {{Steampunk}} cyborg voiced by the 1961 'singing' computer IBM 704.
** Otto Mozer, a cyborg MadScientist voiced by the 1975 chip the TSI [=S14001A=] (the soundchip used to provide the voice of Evil Otto in the game ''VideoGame/{{Berzerk}}'' as well as voices from ''VideoGame/{{Ghostbusters 1984}}'' and ''VideoGame/ImpossibleMission''.). The name is a homage to both Evil Otto and the designer of the chip, Professor Forrest S. Mozer[[https://en.wikipedia.org/wiki/Forrest_S._Mozer]].
** Lady Parsec, a SilkHidingSteel robot queen/despot voiced by the [=TI-99/4A=] plug-in speech synthesizer module for the game ''VideoGame/{{Parsec}}''.
** Lady Parsec HD, based on a mixture of Lady Parsec's master audio files and new phonemes provided by a similar-sounding voice actress.
*** The latter suspected to be [[https://twitter.com/plgDavid/status/634374584800800768 the wife of the head developer, David Viens]].
** Bert Gotrax, a foul-mouthed robot boy voiced by the Votrax SC-01 chip used in ''VideoGame/{{QBert}}''.
** Dee Klatt, a {{GenderBender}} cyborg voiced by [=DECTalk=] (Steven Hawking's voice unit).
** Spencer [=AL2=], an EnergyBeing voiced by the [=SP0256=]-[=AL2=] chip used in a number of 80s kit speech synthesisers including the Intellivoice Intellovision attachment and the Magnavox Odyssey voice attachment.
** Terminal 99, a mysterious computer that [[AGodAmI may have absorbed its programmer's souls and is worshipped by them as a god]], voiced by a TI [=99/4A=] plugin synth module.
** VOSIM, a robot companion scrapped for being TheUnintelligible who [[IJustWantToHaveFriends tries to make friends with others]], voiced by a standard DAC. Notably, his voice is more synth like than the others.


[[folder: Toys ]]

* Texas Instruments' ''Speak n' Spell'' toys deserve a special mention due to the fact that they have a very early TI synthesizer, model [=TMC0280=], that the PeripheryDemographic loves to abuse.
* Several early V-Tech educational computer systems also has optional speech modules that can be purchased separately and added to the toy to provide speech.


[[folder: Video Games ]]

* The ''VideoGame/{{Portal}}'' [[VideoGame/{{Portal 2}} series]] is an aversion of this, since its evil [=AIs=] are voiced by humans (heavily edited in post-production, but humans nonetheless). [=GLaDOS=] ''was'' originally going to be voiced by a text-to-speech program, but Valve wanted her to go through a VillainousBreakdown where she became progressively more emotional, which computer programs couldn't do.
** The results of running the text of [=GLaDOS=]'s lines through a text to speech program were actually used to coach actress Creator/EllenMcLain with regard to giving [=GLaDOS=] her distinctive voice in ''Portal''.
** However, fan-made mods can't afford Ellen's voice (though, once people ''did'' think of asking her), hence, they use voice synthesizing programs for their [=GLaDOS=]es and [=AIs=] (dependent on the story for the mod). However, Ellen does [[http://kotaku.com/5833377/when-glados-asks-you-to-marry-someone-you-say-yes make exceptions]] and has provided her service in the voice of [=GLaDOS=] for a much smaller fee for fan projects in the past.
** This only becomes apparent in the mod ''[[VideoGame/PortalPrelude Portal: Prelude,]]'' whose main gimmick is that the test supervisors were human, rather than an AI. However, the voices were done in a text-to-speech program because the creators were French and weren't very fluent in spoken English. They couldn't find voice actors in the timeframe in which they wanted to develop the game.
*** This becomes especially awkward towards the end of the game after [[spoiler: [=GLaDOS=] is turned on for the first time, and she uses her sound files from the main ''Portal'' game, mixed with synthesized voices. So we have a robot that sounds more human than the humans do, and uses two personalities at once.]]
*** For those of you keeping track: ''Portal''[='s=] supervisors are robots voiced by humans imitating robots imitating humans, while ''Prelude''[='s=] supervisors are humans voiced by robots imitating humans.
* ''VideoGame/{{Beatmania}} IIDX 15: DJ TROOPERS'' used Microsoft Sam for the "[[{{Engrish}} Enemy Plane Appoach]]" voice in the music used for AttractMode and some of the menus.
* Deliberately used ''badly'' in ''TimeFcuk''--the main character's voice is barely even comprehensible, and definitely doesn't sound human. It's not quite certain why this is--perhaps the RuleOfScary, or a deliberate attempt to "[[TheEveryman anonymize]]" him?
** If you listen closely, the main character talks exactly how it is written.
* The voice of Byte from ''[[VideoGame/TronTwoPointOh Tron 2.0]]'' is actually a voice of [=MacinTALK=].
* ''VideoGame/ImpossibleMission'' on the Commodore 64: "Another visitor? Stay awhile. [[PunctuatedForEmphasis Stay FOREVER]]!" [[note]]The strange thing about this is that the trope is actually ''zig-zagged'': The speech is actually provided by a TSI [=S14001A=], but it was converted to PCM digital audio and played back using the SID PSG instead of being produced on-the-fly using the PSG. The story behind the reason is a little funny- game programmer Dennis Caswell went to a startup called Electronic Speech Systems and requested for digitized recordings of a "50-ish English Guy". They gave him recordings done using said synthesizer chip and he was none the wiser (when interviewed about the game later, Caswell was still under the impression that the voice belonged to a human[[https://en.wikipedia.org/wiki/Impossible_Mission#Development]]), and went on to include the samples in the game.[[/note]]
** On the side note, the Commodore 64 and 128 has an add-on module called the ''Magic Talker'' that gave it a synthetic voice with a limited vocabulary of 235 words.
* Several AppleII sound cards include a speech chip, if not a DIP socket for a speech chip upgrade. Usually these take Votrax SC-1 or SSI-263 chips.
* Microsoft Sam and Mary appear chanting the name and motto of the Wii party game, ''Let's Tap'' in the game's theme tune. [[EarWorm Yes, really.]]
* The Intellivision's Intellivoice module.
* The ''VideoGame/HouseOfTheDead'' series used these in the first two games. Which, of course, made for some hilariously emotionless bits of drama. As well as the infamous "Suffer like G did?"
* ''VideoGame/MoonbaseAlpha'' has this for players. This leads to [[MemeticMutation notorious]] [[http://www.youtube.com/watch?v=Hv6RbEOlqRo griefing possibilities]].
* ''VideoGame/AnimalCrossing'' uses a simple voice synthesizer to speak each letter of the text, very quickly. Characters even add the proper inflection if a sentence ends with a question mark. It's fairly unintelligible if you try to listen to it, but in the original Japanese it works a lot better, in fact, almost perfectly, since the Japanese language used a series of fixed pronouns compared to western languages which phonemes has to be combined to form words.
* ''VideoGame/QBert'' uses a Votrax SC-01 voice synthesizer chip[[note]]Also used in their pinball machines such as Pinball/BlackHole[[/note]] to supply the voices of the various characters. Unfortunately, the chip used couldn't produce coherent phrases[[note]]Well, actually it could, but it mostly wasn't good enough for what they were looking for. Q*Bert himself does say one phrase when the machine is turned on: "Hello, I am turned on". He also says "Bye-bye!" after the player enters their initials on the high score list.[[/note]], so the designers decided to go the other direction and have the characters speak a StarfishLanguage.[[note]]WordOfGod is that the programmer in charge of programming the speech was too frustrated with the chip's API due to how hard it was to get it to say what he wanted properly, and simply decided to give up and have Q*Bert speak gibberish after programming the abovementioned two phrases[[/note]]
* Zimos in ''VideoGame/SaintsRowTheThird'' speaks with an {{AutoTune}}d electronic voice box.
* Creator/{{Stern}}'s ''VideoGame/{{Berzerk}}'' is likely the UrExample for video games. It was either this game, or Creator/{{Midway}}'s VideoGame/WizardOfWor; both were released the same year (1980).
* Averted with Creator/WilliamsElectronics' infamous VideoGame/{{Sinistar}}, which used a CVSD-based[[note]]The predecessor of PCM[[/note]] HC-55516 to play back digital audio- Sinistar's speech were digitized recordings of radio personality ''John Doremus''.
* The Remnant Psyches in ''VideoGame/{{Killer7}}'' all use text-to-speech voices. In the original Japanese, [[http://youtu.be/iwre4JstX_A they're speaking slightly-hard-to-make-out-but-still-understandable]] GratuitousEnglish, but in the English dub, everything they say is run through extra audio filters to [[http://www.youtube.com/watch?v=YwQSXqg348c&t=1m2s make them]] [[http://www.youtube.com/watch?v=SjIca60-QRU&t=0m42s more incomprehensible.]]
* As an AprilFoolsDay joke, Four Leaf Studios [[http://katawashoujo.blogspot.com/2009/04/technology-prevails.html announced]] that ''VisualNovel/KatawaShoujo'' will be fully voiced thanks to voice synthetisation technology.
* The 2013 ''VideoGame/RiseOfTheTriad'' reboot uses the same synthesizer as ''VideoGame/MoonbaseAlpha'' for it's text chat in multiplayer. Many of the memes follow suit.
* The fan-made Yukkuris in the ''VideoGame/{{Touhou}}'' franchise tend to be voiced like this.
* ''VideoGame/TomodachiLife'' has this for every character, and lets you customize the voice using various sliders. The difficulty of getting the text-to-speech working in languages other than Japanese was responsible for slowing down the game's western release. (The first game was not localized at all due to the DS not being able to properly run an English text-to-speech system)
* In the laserdisc arcade game Film/{{Firefox}}, this is how "Mitchell Gant" (Creator/ClintEastwood's character from the movie) is portrayed.
* ''VideoGame/PeasantsQuest'' from [[WebAnimation/HomestarRunner The Brothers Chaps]] uses this for Trogdor's voice. WordOfGod is that they used the ''Software Automatic Mouth'' program (mentioned below) on an UsefulNotes/AppleII with a supported sound card to generate the source speech.
* ''[[http://www.indiedb.com/games/nsfw-not-a-simulator-for-working NSFW - Not a Simulator For Working]]'' ([[https://www.youtube.com/watch?v=cXYSlRwPfX0 playthrough by Markiplier]]) uses various synthetic voices to create the "porn sounds", which kicks it straight into the realm of {{narm}}.

[[folder: Web Animation ]]

* In her early design, Rya from ''WebAnimation/BonusStage'' was voiced by a Macintosh text-to-speech synthesizer, but later went on to just having a robot-sounding voice.
* The announcers (often called "speaker boxes") from ''WebAnimation/BattleForDreamIsland'' are all using computer-generated voices. The only exception to these are announcers based off existing characters.
* Everyone in ''WebAnimation/GreenyPhatom''. Literally everyone.
* The idea behind ''WebAnimation/IfTheEmperorHadATextToSpeechDevice'' is that someone eventually gave [[TabletopGame/{{Warhammer 40000}} the God-Emperor of Mankind]] access to a keyboard and a voice synthesizer, so naturally he's voiced by one.

[[folder: Web Original ]]

* The Hymn of None in ''WebVideo/LG15TheResistance''.
* Gary [[spoiler:aka Gamma]], the AI/computer from ''Machinima/RedVsBlue''.
** He regularly appears as the announcer for the Red Vs. Blue theory discussion podcast, Let's Figure This Out Shizno.
* Since Creator/DougWalker was traumatized into muteness by the terrible, terrible movie,[[note]][[WrittenInInfirmity actually a throat infection]][[/note]] WebVideo/TheNostalgiaCritic is forced to review ''Film/AloneInTheDark2005'' through Speakonia. At least [[WebVideo/AtopTheFourthWall Linkara]] and [[WebVideo/TheSpoonyExperiment Spoony]] are there to help.
* Pollo of ''WebVideo/AtopTheFourthWall'', the the ''ComicBook/RomTheSpaceknight'' retrospective, when the title card artist, Alex "Masterthecreater" Tansley, takes over. This is mostly because of copyright issues with the software, as the character was TheVoiceless on the [=DVDs=].
* That's the primary trait of WebVideo/{{IGSRJ}}, courtesy of Loquendo.
* The titular Gantz in hbi2k's ''WebVideo/GantzAbridged''.
* The Rito in a ''VideoGame/TheLegendOfZeldaTheWindWaker'' [[TheAbridgedSeries abridged series]].
* The judge in an ''WebVideo/AceAttorneyAbridged'' series uses a Spanish voice program.
* There's an audio file kicking around the Internet called "Text-to-Speech Theatre Does '[[ComicBook/ChickTracts Dark Dungeons]]'."
* The eponymous characters and Cortana of ''Machinima/ArbyNTheChief''.
* WebVideo/BarneyBunch videos use Speakonia for every character.
* From the amount of Loquendo videos on Website/YouTube, you'd imagine half of Latin America's a robot.
* {{Anonymous}}, for obvious reasons, uses a text-to-speech software for their Youtube videos.
* WebVideo/TheFanFictionCritic has a software called Diane that reads the excerpts from the fanfiction she reviews. (She's also given Diane extra text on top of the excerpts to the point of making her a SnarkyNonhumanSidekick character.)
* "[[VideoGame/ZeroWing All your base, your base]] / [[StupidStatementDanceMix base, base]] / [[MemeticMutation All your base...]] [[AllYourBaseAreBelongToUs Are belong to us]]"
* The entire premise of ''WebVideo/MicrosoftSamReadsFunnyWindowsErrors'' is having these [[ExactlyWhatItSaysOnTheTin (usually Microsoft Sam)]] read... [[ExactlyWhatItSaysOnTheTin funny Windows errors]]. However, it is subverted at one point where one error is read out by creator Thunderbirds101 himself.
* ''WebAnimation/RatboyGenius'' uses them for every character.
** Except Happyman, Green Monster, the Summer Solstice Baby, and all characters in the Red Planet and Galactic Superheroes series, which are all creator Ryan Dorin's voice heavily pitch-shifted and in many cases [[AutoTune autotuned]].
* The [[HeManWomanHater anti-MRA]] video "[[http://vimeo.com/64941331 But I'm A Nice Guy!]]" uses this for the StrawMisogynist main character.
* Android 19 in ''WebVideo/DragonBallZAbridged'' is voiced by a text-to-speech program (except for a single line that required a less monotone delivery).
* Puppycat of ''WebAnimation/BeeAndPuppycat'' is voiced by the Music/{{Vocaloid}} Oliver.
* #1 in Machinima/TheGmodIdiotBox uses the voice of Microsoft Sam when he's seated in front of a computer.
* The memetic [=BonziBUDDY=] program uses a computer-generated voice, which probably helped make it so infamous.


[[folder: Western Animation ]]

* H.E.L.P.eR. from ''WesternAnimation/TheVentureBrothers'' is voiced by something called "Soul-Bot", which processes Chris [=McCulloch=]'s "eep!" noises into electronic beeps and boops.
* AUTO from ''WesternAnimation/WallE''. As if there weren't enough Apple references in the movie already, the voice is [[UsefulNotes/MacOS Mac OSX's]] own [=MacinTALK=]. Similarly, M-O's "Foreign Contaminant" is provided by [=PlainTalk=].
* The title robot in ''WesternAnimation/WhateverHappenedToRobotJones'' originally used [=MacinTalk=] Junior, credited as "Himself", but later switched to a synthesized human voice, and they even redubbed the earlier episodes with the real actor.
* Compuhorse from ''{{WesternAnimation/Spliced}}''
* Post-''ReBoot'' CGI series called either ''War Planets'' or ''Shadow Raiders'' had Princess Tekla (from the robot planet)'s companion device voiced by [=MacinTalk=].
* ''[[WesternAnimation/TransformersAnimated Animated]]'' Perceptor's voice is completely synthetic, and probably so to bring to mind Professor Stephen Hawking. One of the writers has suggested that he "deleted his emotions and personality" to make room for more data, though (like many an "emotionless" character), [[TinMan he certainly seems to have both]], if understated.
* Steve the Disabled Professor (a Creator/StephenHawking stand-in) in ''WesternAnimation/FamilyGuy'' also used Macintalk. Ironically, three episodes also had animated [[SesameStreetCred cameo appearances]] by the real Stephen Hawking.
* That locomotive from ''Disney/{{Dumbo}}'', despite being male according to the song "Casey Junior", is actually voiced by a woman, as revealed in ''Disney/TheReluctantDragon''.
* ''WesternAnimation/TheBOTSMaster'' used a synthesized voice for the evil Corp's robots, while the BOYZZ were all voiced by real actors. This was done to show that the BOYZZ were more human than their soulless corporate adversaries. To be exact, Creative Labs'[[note]]Best known for their "Sound Blaster" line of PC sound cards.[[/note]] [[https://en.wikipedia.org/wiki/Dr._Sbaitso Dr. Sbaitso]] program is used. To make things more interesting, Sbaitso actually uses Creative Text Assist (itself already used for several movies) for it's speech backend.


[[folder: Real Life ]]

* NOAA Weather Radio went to all-synthetic voices in the late '90s, with most stations have one male and one female synthetic voice, and a Spanish-speaking voice is used where needed. This is also done for Canada's Weatheradio service, with stations alternating between English and French voices. Select TV stations will use synthetic voices for their Emergency Alert System tests as well, and Canada exclusively does for their equivalent Alert Ready warnings.
* Surprisingly, [[UsefulNotes/AppleMacintosh Siri]] averts this - voice actress Susan Bennett (and her international counterparts) spent five hours a day for four weeks voicing seemingly random words for [=ScanSoft=] (the company behind Siri's technology), who then sliced them up to form the phonemes and intonations that the search engine uses.
* The Software Automatic Mouth, or SAM, by Don't Ask Software, provides a CPU-driven speech synthesizer to any machine that has a PSG chip. The Apple II version supported several PSG-based sound cards made for the Apple II (and was a pack-in software for several cards), and the [=C64=] version drives the SID chip directly. The Atari 8-bit version used the POKEY chip (another PSG chip on Atari 8-bit computers that can also be found in several arcade machines), but had other limitations due to the design of the system (the ANTIC chip had to be disabled, as do interrupts- this means that the screen has to be blanked while generating speech). The PC and base Apple II version can even try to generate speech from the internal beeper by treating it as a rudimentary PSG. [=MacInTalk=] was a rebranded version of this software that Steve Jobs personally commissioned Don't Ask Software to produce for the Mac (which went on to voice AUTO in ''WesternAnimation/WallE'', among many other roles). Microsoft Voice/Speech (of which Microsoft Sam is a part of) is also undoubtedly its spiritual successor if not direct spinoff or even direct continuation of the line.
* Creator/StephenHawking, famously, whose distinctive MachineMonotone voice is probably the TropeCodifier inspiring many of these examples. Many people who are unable to talk for medical reasons have followed in Hawking's lead, which is much easier and more affordable now due to technological advancement. Averted with famed heavy metal guitarist Jason Becker (who suffers from ALS and can only move his eyes and some facial muscles), as he and his father devised an eye movement system that allows him to convey messages faster than he could with a computer.
* In the 1980s, Texas Instruments released the Vocaid, a modified Speak & Spell that allowed people who were physically unable to talk to speak with a robot voice. Pre-loaded voice samples and button overlays allowed the user to call 911, request assistance from caregivers, spell letters & numbers, and even speak when playing card games. The Vocaid is very much an outdated product now, but it has attracted some attention in modding communities in recent years.
* Pulitzer Prize winning film critic Creator/RogerEbert used a computer to communicate after he lost his voice due to thyroid cancer. Software engineers began using clips from DVD commentaries that he recorded to synthesize his own voice, which he demonstrated on ''TheOprahWinfreyShow'', but his variant wasn't fully completed before his death.
