Black Speech

"''"Ash nazg durbatulûk, ash nazg gimbatul, Ash nazg thrakatulûk agh burzum-ishi krimpatul"''"

- The Lord of the Rings: Inscription on the One Ring, with inflection

The language of Mordor, spoken only by The One Whose Name Must Never Be Uttered and his evil Cult. An indecipherable language that is cruel to the ears, full of hard consonants, guttural sounds, and always spoken loudly and harshly. Every word sounds like a blasphemy against All That Is Good, and the people speaking it often are as evil as they sound. If there is magic in the setting, expect speaking this language to be necessary to use Black Magic. In some cases, it is so alien and gravelly that it seems that a normal human throat should be incapable of speaking it...and sometimes, they can't speak it, only those with the Voice of the Legion can.

This is The Black Speech, the default mode of communication for the Designated Villain, and the sonic equivalent to black in Color Coded for Your Convenience. Where the elves and humans will speak in a pleasing, song-like language, and dwarves may (read: always) have a charming Scottish burr or Welsh brogue, the Evil Minions using Black Speech can shatter glass and eardrums with a simple "pass the salt".

On a more meta level, this is a direct emotional appeal to the viewer, invoking the "otherness" felt when hearing a foreign language crossed with the Scare Chord to make the good guys seem like downright saints compared to the bad guys. The effect is sometimes doubled by having Aliens Natives Speaking English.

Once upon a time, Nazis speaking German were considered to be using Black Speech (likely, the actors were hamming it up to sound scarier). Nowadays, German is just another language alongside French.

Using real but obscure languages as models for a fictional Black Speech owing to their very peculiar sound can get you into trouble. This seems to happen to Native American languages quite a bit.

Not to be confused with Ebonics. Please.

'''No Real Life Examples, Please. That's just asking for a Flame War.'''

Anime & Manga

 * In Dragon Ball, King Piccolo would speak to his minions and mind slaves in some strange tongue. Retconned in DBZ, where he's explicitly an alien and it was just his native tongue.
 * Sayonara, Zetsubou-sensei: if Meru's cellphone is moved out of reception range/broken (she ONLY communicates by text messages), she'll snap and start speaking like this, taking an exorcism a huge crucifix to the head to stop her.
 * The titular character of Ah! My Goddess, while benevolent, uses a language like this for some of her spells. (It's part of a larger issue of understanding between her and the male lead.)

Comics

 * The wicked rat creatures in Bone have a secret language called Nessen that sounds mysteriously like broken German.
 * Mind you, Nessen is closer to a military cypher than actual black speech: Ratmen speak in human language normally and only switch to it when they're discussing sensitive subjects and are afraid to be overheard. Several humans listen in to it without any worse effects than "cannot understand any of it", and some of the characters like Lucius can also understand it.
 * The Invisibles has a section where Miss Dwyer, a servant of the Conspiracy who's pretty much out of options, is about to let loose a string of hyperdimensional language that can give those it's directed at cancer. As the narration describes it, "Miss Dwyer is saying her prayers."

Films

 * 10,000 BC has the slavers speaking an incomprehensible, guttural language, and certain characters have their voices digitally distorted to make them sound inhumanly guttural.
 * All but one of the vampires in Thirty Days of Night speak like they tore out their own windpipes. (In fact, the filmmakers took the sound of an Amazonian language and mixed in animal noises.) This is not true of the comic in which they spoke English, albeit in colored Speech Bubbles.
 * Beowulf has Grendel speak Old English (the language in which the poem was originally written) while everyone else speaks modern English, it's probably to emphasize how old the race of monsters is. It should be noted that old English from far enough back is actually old German, although that's certainly simplifying things quite a lot. For those who think it's odd to consider Old English to be Black Speech, we recommend reading The Canterbury Tales in the original Middle English. Interestingly, his mother speaks both old and current English, making her bilingual. Brains and scaly beauty, it seems.
 * Pathfinder has a similar set up with 10,000 BC, with the good guys speaking English and the invading Vikings speaking Icelandic, but in a very guttural fashion. The original had this, too, with the heroic Saami speaking Saami and the evil, invading Tshud speaking influenza.
 * Played for Laughs in the Adam Sandler movie Little Nicky, wherein the titular character is the youngest Spawn of Satan. Although he normally speaks in a nonthreatening nasally voice, he talks in his sleep, inevitably demonically. Listening to it induces manic paranoia in his roommate and drives animals crazy. Seemed to be pleasant to a pair of stoner death metal fans, however ...
 * His guide, a talking dog, sings like an angel in his sleep.
 * Used humorously in the film version of The Hitchhiker's Guide to the Galaxy when the Vogon commander switches effortlessly from a charming Received Pronunciation accent to one of these in under a second. (In the book, Vogon speech is: "like a man trying to gargle whilst fighting off a pack of wolves".)
 * Constantine briefly gives us an example of "Hell-speak".
 * There's a Filipino movie where two devils speak in their native tongues. The subtitles apologize to the viewer for the lack of translation because they don't know anyone who's been in Hell before.

Gamebooks

 * The Giak tongue in the Lone Wolf series and spin-offs. Spoken by the Darklords and all of their minions in the Darklands, as well as the evil humans, the Drakkarim. Certainly looks harsh-sounding when transcribed, and is described as such. Complete with a full Fictionary.
 * And then there's the Dark Tongue, which humans aren't even able to speak. The only ones who ever speak it in the series are the Darklords themselves. The Darklords use the Dark Tongue to summon nasties to fight Lone Wolf.
 * Funnily, Giak seems to be the only tongue Joe Dever ever developed for his world. So if you want to immerse yourself linguistically into Magnamund, you're forced to do so with the ugly tongue (crude grammar, nasty vocabulary) of the Bad Ones' cannon fodder. Too bad.

Literature
"It wasn't a word. It wasn't even so much a proper sound. Just giving voice to it made her mouth hurt. But it did a lot more to Suldon. He instantly, explosively vomited, then fell onto his knees, clutching at his belly, violently retching up his stomach contents."
 * Named for the language of Mordor in The Lord of the Rings (books and movies). "The Black Speech" is an unpleasant-sounding language full of guttural throat-growls and spits and snarls; unpleasant and alien to the more pleasant languages. Black Speech acquired some sort of a fandom because of the inscriptions on the ring, much to the dismay of its creator, who had put everything he hated into this language. In fact, a fan once gave Tolkien a goblet with the inscription from the ring in Black Speech as a gift, but Tolkien found the language so ugly (and the words so ominous) that he couldn't bring himself to drink out of it. He wound up using it as an ashtray.
 * Both book and extended film versions of the story include a scene where Gandalf uttering the Black Speech verse from the Ring causes the sky to grow dark and the Earth to tremble; the film version even gives Gandalf a Voice of the Legion effect for good measure, with what seems to be Sauron's voice speaking along with his own. The Elves are not amused.
 * Notoriously, Black Speech is the least developed of Tolkien's artificial languages (the fact that it might possibly be based on some Slavic or Hungarian dialects probably kept it from appearing too frequently). Word of God only provides two examples: the Ring verse in a formal register, and an offensive diatribe in 'vulgar' Orcish Black Speech. That didn't stop people from being fascinated by its potential as evil-defining: movie linguist David Salo extrapolated a richer language for the villains and the soundtrack, and (less professionally) Tolkien-influenced black metal bands like to compose songs in faux Black Speech. Tolkien would probably be appalled at those.
 * The Russian linguist Alexander Nemirovsky found that this language is quite similar to Hurritic and was probably inspired by it.
 * While the Black Speech was invented by Sauron, some of its vocabulary seems to have been based on Valarin, the language of the angelic Valar. Interestingly, Valarin is described by one elven scholar as sounding "harsh" to species other than the Valar, while others, again, have different opinions.
 * The Black Speech being based on Valarin is possibly justified by the fact that Sauron is a Maia, who are the same race as the Valar, just on a lower power level.
 * In Ella Enchanted, the Prince's reaction to Ella's simple farewell in troll language is, "It sounds evil." Ella replies that it is.
 * "The Call of Cthulhu" by HP Lovecraft has several languages spoken by cultists which sound and look disturbing.
 * In The Shadow Over Innsmouth, the mutant inhabitants of the eponymous town have guttural, slopping, croaking voices that are frightening to hear. The narrator indicates that they have their own blasphemous language to go along with it.
 * Slightly unrelated, but I think I've discovered what language Cthulhu would speak if he was real, dubstep. It's a sound that is inherently disturbing to the human ear and totally incomprehensible. Isn't that what Cthulhu's voice was described as?
 * Terry Pratchett steered clear of this one: Dwarfish is very difficult "if you haven't eaten gravel all your life", but isn't evil as such. Likewise, the Troll language, which seems to consist of tonal grunting. The words of certain spells, however, can make you feel distinctly ill. And a language called Black Oroogu mentioned in The Colour of Magic has "no nouns and only one adjective, which is obscene."
 * When he gets an actual voice (in the computer games, for example), he tends not to be particularly sepulchral, but merely exaggeratedly deep and slightly echoey.
 * War has a voice compared to clanging chunks of lead, and Pestilence to a drop sliding inside a coffin.
 * Having a discussion with a troll in Troll language could very well lead to receiving a bonk on the head, though. You see, Trollish is in large part a body language, and trolls like to shout...
 * Also, in many Troll dialects, extending one's hand is a very rude comment about their mother. It is amazing how long it took for trolls and humans to understand this.
 * The Molvanian language as described in Molvanîa, A Land Untouched by Modern Dentistry is supposed to have a highly irregular grammar and difficult pronunciation, often requiring crude gestures to make simple phrases intelligible. Readers are advised: "Due to the abundance of guttural phonetic sounds found in the spoken language, non-native Molvanian speakers are warned about the risk of laryngeal damage that can arise from attempting anything more than a few short phrases."
 * The real-life source is likely the Georgian languages. Try the words starting with eight consonants.
 * But the proper way to pronounce Georgian is very lightly, so even eight consonants should not be so troublesome.
 * Diana Wynne Jones's Tough Guide To Fantasyland contains a similar warning about pronouncing ominous-sounding placenames such as Gna'ash if you have "insecurely mounted tonsils".
 * While the Black Speech in Bentley Little's The Vanishing sounds normal to a character who discovers he can read it (thanks to unknowingly being a descendent of the race of monsters who originated it), when he finishes reading it aloud, the people around him inform him he's been screaming like a wild animal. Even trying to read in a whisper isn't enough to lessen the language's cacophonous effect. Also, speaking it makes plants grow.
 * In Larry Niven's Known Space series, the Kzinti Hero's Tongue is reputed to sound like an epic catfight. Thoroughly appropriate for a race of felinoid slave-takers.
 * Two speaking normally are described as a catfight in an echo chamber, four arguing among themselves as 'A major feline war, with atomics'.
 * Harry Potter has Parseltongue, the language of snakes.
 * Although even that isn't inherently evil; Harry has a perfectly civil conversation with a very nice snake in a zoo in the first book. It simply gained a very unpleasant association from the fact that Salazar Slytherin and his descendants, including Voldemort, could speak it.
 * In Jonathan Strange and Mr. Norrell, re-animated dead Italian soldiers initially speak one of the dialects of the Language of Hell (they were all Papists, so of course they were all damned), which is described as "...having a much higher percentage of screams than any language known to the onlookers." (Wellington approves of their having mastered it after having been dead for only three days.)
 * In Arthur Machen's novella The Three Imposters - not surprisingly, a favorite of HP Lovecraft - a boy from the country begins speaking in a strange tongue of his ancestors: "He seemed to pour forth an infamous jargon, with words, or what seemed words, that might have belonged to a tongue dead since untold ages and buried deep beneath Nilotic mud, or in the inmost recesses of the Mexican forest. For a moment the thought passed through my mind, as my ears were still revolted with that infernal clamour, 'Surely this is the very speech of hell.'"
 * The Redemption of Althalus, by David Eddings: the Book of Daeva is effectively written in this.
 * In the Warhammer 40000 novel Ravenor Returned, there are words (or rather, "unwords") which, when read, can disorientate and, when spoken, tend to damage the lips and teeth of the speaker. The effect of a single word on the targeted listener is worse. A lesser word, or fragment of one:


 * In Rob Thurman's Cal Leandros novels, the language of the Auphe is impossible for humans to speak and almost impossible for supernatural beings to speak. Hearing it "feels like someone shoving ground glass in your ear." It is described as damaging the air and the universe itself whenever it is spoken.
 * Charles Stross' The Laundry Series, based partly on the Cthulhu mythos, has the old Enochian languages, mainly used for writing magical "computer code" in order to, say, command zombies. It is described as a "dead tongue, for which to command dead things", completely unsuitable for the human larynx. Don't even think about making an experienced magician swear in that language.

Live Action TV

 * The language of the Goa'uld of Stargate SG-1 isn't technically an evil language, considering townspeople and Jaffa speak it, and it's supposed to be based on Ancient Egyptian...but when spoken by a Goa'Uld with their flanged voices and glowy eyes? Running seems a good option.
 * Considering how often O'Neill pointed out mistakes in their grammar, maybe they just felt safer that way. Also, English as spoken by snakeheads is pretty damn Black, too.
 * That language has way too many expressions that translate as "Surrender or die!".
 * In Torchwood, Owen speaks in this while The Grim Reaper passes through him.
 * Ironically, the magic words Owen repeats in that demonic voice are taken from Stephen Donaldson's The Chronicles of Thomas Covenant, in which they are the "Seven Words", a blessing.
 * If you're going to speak Klingon, have a glass of water handy. Your throat will thank you.
 * Klingon's actually just got the phonics of Tlingit, a Native American language (chosen because most of its sounds are pretty unusual). The biggest thing making it sound inhuman is speaking it with Klingon prosthetic teeth. The brujo in The Missing has similar fake teeth, and sounds exactly like a Klingon when he speaks Apache (distantly related to Tlingit).
 * The Breen in Star Trek Deep Space Nine speak an electronic-sounding, guttural tongue.
 * The Kamen Rider series has a few examples, such as the languages of the Grongi and Undead. Additionally, we see the Imagin language written but not voiced, and the Fangire tongue is long-forgotten and only spoken by Sagarc, Kamen Rider Saga's high-voiced, living Transformation Trinket, which makes it sound less than imposing.
 * The language of an ancient sinister race of Shadows in Babylon 5 consists of barely comprehensible rustle, chirps, and humming, and, in case of their living battleships, eardrum-puncturing shrieks. Although the human emissaries of Shadows can understand them (probably due to some implants), they cannot speak in Shadowish themselves. It's stated that, for example, the true name of the race is about 10,000 sounds long and is completely unutterable.
 * Similarly, the Shadows' nemesis, the Vorlons' natural "voice" is heard as an odd combination of chimes, wind, and other electronic effects. The Shadows' servants, the Drakh, have an alien language as well, which is spoken in a whispered (and sinister) manner, much like Ralph Fiennes' rendition of Voldemort (and when they do speak English, they whisper it too).
 * Enochian in Supernatural. Partly subverted in that it's used in just about equal measure by both good guys and bad guys (chiefly for spells and exorcisms).

Music

 * Death Metal and Black Metal vocals often sound like Orcs' Black Speech. Although most bands sing in English and other natural languages, it is usually distorted to the point of being unintelligible.
 * Many viking/folk metal bands from Scandinavia use their native languages, unintelligible to most of their audience (if they build up a fanbase abroad, that is), for authenticity. An exception is Finntroll, who sing in Swedish, instead of their native Finnish.
 * Summoning, a Lord of the Rings-themed black metal band, went one step further by actually writing a song in the Black Speech. It's called Mirdautas Vras (trans. "A good day to kill") and it's awesome. Listen here.
 * Parodied by Martin Pearson in his Lord of the Rings-themed folk-comedy show "The Lost Spelling Errors of Bolkien", in which he sings the One Ring's inscription to the tune of "King of the Road" in a voice that borders on an Elvis impression.
 * Similarly parodied in Eben Brooks' "Hey There Cthulhu", where the above quote from "The Call of Cthulhu" is sung to the tune of "Hey There Delilah" by the Plain White Ts.
 * "Cthulhu fhtagn" has also been filked to the tune of "Hakuna Matata".
 * Norwegian Black Metal band Burzum's name comes from the actual Black Speech. It means "Darkness".
 * Other metal bands with a name in a Tolkien language are Gorgoroth (the plateau around Mount Doom) and Amon Amarth (the Sindarin name for Mount Doom itself).
 * Tool has a song called "Die Eier von Satan" that plays on the preconceived notions of the German language. The song consists of the singer growling German over clanging industrial beats, punctuated with apocalyptic cries that are greeted by a roaring crowd. The overall effect is somewhere between a Black Mass and a Nazi rally, but the translated lyrics show that the speaker is reciting a recipe for egg-shaped hash brownies. His rallying cry, "Und keine Eier!" means, "And no eggs!", since there are no actual eggs in the recipe. "Eggs" are also an informal term in German for testicles, giving the hash brownies a rather silly, scatological name: "Satan's Balls."
 * Norwegian Folk Metal band Trollfest write their lyrics in a constructed language they call Trollspråk, a mix of German and Norwegian which, when combined with the band's growly Black Metal vocals, can sound very evil.
 * Finnish experimental metal band Aarni doesn't make ancient Egyptian sound nice.

Tabletop Games

 * Dungeons & Dragons has a few examples:
 * The Book of Vile Darkness has the Dark Speech, which is the language of pure evil and destruction. Speaking it can cause pain to the good and neutral creatures. By contrast, the Words of Creation are the direct opposite, and can help create things as well as bind evil power.
 * The line above about "...shatter glass and eardrums..."? The Warlock in 3.5 has the invocation Baleful Utterance, which duplicates the spell Shatter and can potentially deafen opponents. And yes, he does it with Dark Speech. More specifically, he does it by uttering a random syllable -- the 'invocation' itself is basically a safety device that keeps the Warlock's brain from realizing what the mouth just said.
 * Infernal and Abyssal are the native tongues of devils and demons, respectively. They have no special properties, but probably include an impressive array of curse words.
 * In the first edition of the game, Lawful Evil, Neutral Evil, and Chaotic Evil alignments had their own languages understandable only to people of the same alignment. When played at all, they tended to get played like Black Speech.
 * There's also Draconic, the language of dragons and magic.
 * This is parodied in the (chronological) first of the Drizzt Do'Urden books--a mage who seems to be casting a spell in one of these languages collapses with a poisoned dart in his back.
 * Warhammer Fantasy Battle and Warhammer 40000 have daemonic speak, which is written with runic symbols and is nearly unpronounceable to humans. It tends to feature lots of Xs and Zs. In Warhammer there's also the dark speak, a language used by the chaos-worshipping human tribes.
 * Given that the Warhammer Universe is, AT BEST, a Black and Grey Morality world, one could very easily argue that every language is Black Speech in some way. Daemons and Orks are the most obvious examples, but even the Gothic language (that's Earth-based English, to you and me) is described as "guttural" and "ugly" to the Eldar -- who, in turn, are people whose basic written language (Runes) are considered witchcraft by humans, and merely possessing the ability to read them could quite easily result in being burned alive for heresy!
 * The kicker? It is. And, used by humans, it is just as likely to win you demonic possession or insanity as that cup of tea you asked for.
 * The Eldar consider Gothic to be "guttural" and "ugly," but they're also a race of Arrogant Kung Fu Guys. They consider pretty much every race to be backwards and primitive, so it's essentially the same as the origin of the word 'barbarian'...in space.
 * Incidentally, speaking Orkish for any length of time will most likely leave you and any other participants in the conversation heavily bruised and with a lowered self-esteem: as Inquisitor Vail at one point notes, the language consists almost completely of hitting people in the head and insulting them, usually at the same time. Given that this is the worst thing that the language will do to you, Orkish is actually a fairly benign language by Warhammer Fantasy Battle standards.
 * Played With in the case of the Nostraman language. It began as a gutter tongue spoken only by the inhabitants of a planet sized Wretched Hive, and during the Great Crusade aproximately 30,000 members of the God-Emperor's loyal Astartes spoke it as a birth language. However, the only surviving speakers following the destruction of the planet are the now Chaos legion of Night Lords and their slaves/servants.
 * Parodied in Exalted. The Abyssals, who, when enacting their darkest rituals, ritually atoning for misbehavior, or otherwise communing with their Neverborn masters, will often speak in a disturbing, nigh-unpronouncably ominous tongue that seems to have all the traits of the Black Speech...until the Abyssals splatbook reveals that it's complete gibberish that doesn't actually mean anything.
 * In Magic: The Gathering, the language of the Phyrexians appears to be this. In actuality, the spoken part is just gibberish that Wizards is passing off as phyrexian, because Wizards decided to not devote the resources to have employees learn the language. The written part however, is a Constructed Language. They hired a linguist.

Video Games

 * Eredun (often referred to as simply "Demonic"), and its written form, Eredic, in Warcraft games. Lots of Xs and Zs here too. As an added bonus, reading demonic scriptures places your sanity at risk. Presumably, the language of the Draenei, which is based on the uncorrupted version of Eredic and sound quite similar, doesn't have that effect.
 * Additionally, it seems that speaking demonic has a negative effect one one's ability to cast spells for non-demons. Evidenced by the fact that Warlocks can curse an opponent into being able to speak nothing else, which slows the speed at which they can cast spells.
 * In the current expansion pack of World of Warcraft, demonology-spec warlocks have a spell called Metamorphosis, which temporarily transforms them into a demon. While under the influence of this spell they are affected by demon-targeting spells (such as Banish) and speak only in Demonic.
 * Kalimag, the language of the Elementals. Considering it's in use by the Twilight's Hammer cult, it counts. Listen for yourself.
 * There's also the language of the Old Gods, spoken in-game only by them, their servants, and those unfortunate mortals who have been driven insane by prolonged contact. You can view a good sampling of it here. To date, this language does not seem to have its own name.
 * The Scourge has its own language, referred to in the game as the 'language of death'. It appears that only a current or former member of the Scourge can speak or translate it. Amusing if one's character is a death knight, but still has to take a Scourge tome to an NPC death knight to have it translated.
 * Played for laughs in Neverwinter Nights 2: Storm of Zehir. Volo wants a parrot, so you get him one. He gets it to speak something in an apparently demonic tongue. A high enough lore skill allows you to say, "Well, that wasn't very polite." Volo tries again, the parrot says something else, and you can say, "It's not getting any nicer..."
 * Parodied in Fable II with the hollow man, who guards the Stone of Myr'Bregothill. They want to do the hollow dance of Ur'Cyrandoandor upon your bones...if only they could reliably remember what it's called.
 * Resident Evil 4 manages to turn Spanish into the Black Speech, much like some films and such do German. It seems possible to make any non-English language language the audience doesn't speak into the Black Speech if you make it guttural and threatening enough.
 * Similarly, Resident Evil 5 does this with the Swahili spoken by the enemies.
 * In Silent Hill 3, the background music in the church features guttural chanting...or groaning...It's hard to tell. Just run faster.
 * Actually, it's a Hatian Voudoun chant. Don't mess with those Voudoun priests, they'll fuck you up...
 * Ar tonelico's Corrupted Pastalian certainly sounds like this, and the context in which it's used doesn't help.
 * In Knights of the Old Republic 2, Darth Nihilus speaks in a ridiculous, over-the-top evil sounding language that is completely undecipherable, and the player is never given a translation to see what he's actually saying.
 * Probably because it'd make you either go crazy or huddle up into a ball, whimpering to yourself.
 * It's almost certainly ancient Sith. The Exile's translator module doesn't have a setting for that.
 * In Bayonetta, the various angels all speak Enochian, the language of angels. Bayonetta and Jeanne speak it themselves when summoning demons and torture weapons. When the Cardinal Virtues speak it, it's creepy.
 * The cultists of Blood speak a language which is a mixture of Latin and Sanskrit words and grammar. By Blood II, only Zealots and, occasionally, Ishmael still speak it, though some of the Fallen in Shogo: Mobile Armor Division also use it.
 * Arguably, one could make the case for the Geth's light-speed digital communication in Mass Effect as being this, at least in Mass Effect 1  They speak in a language impossible to understand or recreate by 99.99999% of humanity.

Web Comics

 * DMFA: the Insectis race. Apparently, they're bad enough when they're actually speaking English, and then you get to their actual language...
 * According to the author, it's not evil sounding, but it is painful to listen to, like trying to form vowels with the sounds of an angle grinder.
 * Subverted by Luna in Dominic Deegan, who has a couple outbursts in an ancient, guttural language (represented by black word bubbles filled with nothing but punctuation and non-letter symbols) during the too-long March Across Maltak saga. The Shintula and Bikta orcs view her using this language as horrible blasphemy, despite the fact that each outburst makes beautiful greenery appear all around her in an otherwise completely dead landscape.
 * Irregular Webcomic: the several personifications of death talk in ALL CAPS when talking to mortals. They talk normal among peers though, because they don't have to act ominous then.
 * Feline language in Kevin and Kell has some traits of this.
 * In Questionable Content, Hannelore slips into the Black Tongue to rebuff Sven's advances.
 * Then, Dora follows suit, with Glowing Eyes of Doom.
 * In The Zombie Hunters, the evil-looking black Speech Bubbles and glowing white lettering of Night of the Living Mooks contains a frightening cacophany of various gutteral grunts and moans, but to, they increasingly begin to resolve themselves leave the character profoundly disturbed.
 * Last Res0rt plays with this; the Tone language of the Celeste uses this as a vehicle for their Compelling Voice, but...Tone itself is completely silent, only audible to the Celeste themselves and any individuals with the appropriate level of resistance.
 * Homestuck: after going  appears to be incapable of talking outside of this. This naturally leads to a language barrier when she runs into.
 * Minnie and Grim Jr. of "Grim Tales from Down Below" can communicate this way.

Western Animation

 * One of The Simpsons favorite gags is the depiction of Russian and German languages as guttural and hostile to English speakers. In every instance, the subtitles reveal that the speaker is actually saying something pleasant or benign.
