You don't realize it. When screaming (even better if it's an Overly Long Scream), yelling, or even sometimes talking normally, your voice suddenly cracks and deepens or squeaks. It can be embarrassing, and for comedy and/or Narm (or probably for Narm Charm), especially if you're also entering puberty at the time. Or maybe just plain too much testosterone.
This is more likely to happen to male characters, though female characters can also be victims. A common gag is for a nervous character to voice-crack as they say something, then clear their throat and repeat it in a deliberately much deeper voice. When it happens in drama (film/TV), it can be a signifier of fear, sadness or any other kind of emotional distress that causes the voice to crack when the person speaks. In music, it's often considered an Epic Fail for singers.
- In Episode 1 of The Lost Village, Masaki's voice cracks as she tries to calm down the bus driver. We should note that she's already carsick at the moment as she runs up.

- This happens to GoGo during a Hilarious Outtakes reel for Big Hero 6.
- A Running Gag in Teen Titans: Call of Blood is Robin/Damian being embarrassed by his voice cracking because, to quote Nightwing, "Puberty finally tracked him down." First, he tries to avoid talking, and later, a tirade comes out too high-pitched for his teammates to understand. It's especially ironic because the Batman from the future with the Badass Baritone the Titans are hosting for is an adult Damian.
- Played for drama in Fullmetal Abridged—when Edward learns what Shou Tucker did to his daughter, his voice breaks with a mix of rage and despair. It's especially noticeable here:
Alphonse: (stops Ed from killing Tucker) Wait. You say I don't have a heart, and that's true. But I'm not heartless, and neither is Ed. You think you're the same, but you're not. What he did was an accident, what you did was on purpose. That's the difference. And that's why he won't kill you.
Edward: YES THE FUCK I WILL!
- Alice in Wonderland: When Alice attempts to hit a high note when she's singing "All in a Golden Afternoon", her voice cracks, and she can't go on. Apparently, it was a Throw It In moment for that scene.

- Pitch Perfect: When the Bellas do a Team Hand-Stack near the end of the film Chloe lets out a bass bellow, much to everyone's surprise and her embarrassment. (She had just gone through node surgery.) This tells everyone that she can hit the low notes, which as an all-female A Cappella group they have a hard time with.
- Dragondrums opens with Piemur's voice cracking during rehearsal. It's puberty, to his distress, since singing's his only real skill as a Harper (he does catch on quite well with drums, though).
- In Shakespeare's Spy, Widge's voice starts to crack due to puberty. He notes that he's entering puberty pretty late, due to poor feeding in his previous homes contrasted by the better treatment of the troupe. He's rather unhappy to find it means he won't be able to play girls onstage anymore, as they were the parts he'd been accustomed to.
- At the start of the Young Adult novel "Jack and Lousa: Act 1'', 12-year old Jack is about to star in the lead role of a Broadway musical when his voice starts to change. This causes him to be fired from the show.

- Cheers: When Diane starts suffering from a (psychosomatic) allergic reaction, Frasier informs Sam that one of the symptoms is her voice breaks. Sure enough, later on her voice breaks mid-argument, becoming much more nasal.
- The Rolling Stones Gimme Shelter - one of their most famous songs - has a moment at the end of the third hook where Merry Claytons voice cracks as she screams Rape, murder, its just a shot away. Arguably a subversive example of this trope, considering its become well loved by music fans and considered a classic moment.
- Les Guignols de l'Info: A Running Gag for the puppet of François Baroin, at the time speaker for the Chirac administration, and who was the youngest person in said government. His voice always starts normal before cracking mid-speech "because of puberty". Then usually begins a teenage ranting about not being taken seriously.
- In Borderlands 2, Face McShooty's voice cracks several times during his rant on why you should shoot him in the face.
- Non-comedic (and possibly unintentional on Kotono Mitsuishi's part, but still) example: If you listen closely to the Japanese dub of Catherine when Katherine screams loudly on Day 8 after accidentally killing Catherine, her voice starts out really high pitched, and then almost immediately breaks and becomes very scratchy.
- Possible unintentional example in the first Devil May Cry, when Trish seemingly dies Dante cradles her in his arms and screams. In the middle of his yell, his voice cracks. Intentional or no, it works as it conveys just how heartbroken Dante is over the incident.
- In Fallout 4, The Mechanist uses a voice modulator to sound intimidating and dramatic, but occasional spikes imply a higher-pitched voice behind the mask. This is the first sign that the Mechanist is a girl.
- During the London chapter of Fate/Grand Order, Mordred briefly wonders if Hans Christian Andersen's unexpectedly deep voice is from an early puberty, before finding out he's Older Than They Look and that's his natural adult register.
- In Hunt Down the Freeman, when one soldier says "My momma's dead?" Sky Williams, who provides the soldier's voice, squeaks out "dead," and doesn't even finish the line.

- Dutch van der Linde has a bit of this in the Red Dead Redemption series, when he's making incredibly hammy speeches and Chewing the Scenery, also occasionally in regular conversation.
- Red Dead Redemption II: Toward the end of Chapter 6, during the final part of the mountain fight with Micah Bell if the player went with John Marston, while Arthur Morgan is crawling for Micah's revolver, when he says, "In the end, Micah... despite my best efforts to the contrary..." his voice becomes so strained and choked up from his tuberculosis that it cracks into a high-pitched squeak on the word "Micah" and continues squeaking the rest of the words before returning to a normal strain with "...it turns out I've won." Might be unintentional on the part of voice actor Roger Clark, but it counts as Fridge Brilliance in-universe when you discover that when Micah beats up Arthur to the point of being too weak, the latter's TB is worsening and kinda spreads into his larynx (voice box), developing into laryngeal tuberculosis (which is pretty much a rare form of TB), which in turn can cause hoarseness and breathiness (and sometimes falsetto).
- Homestar Runner: In the Strong Bad Email "helium", Strong Bad breathes in helium and thus ends up with a high voice. He starts singing a song about being part of the "High-Voice Crew", only for the helium to wear off in the middle.
Strong Bad: Oh, I guess I got kicked out of the High-Voice Crew.
- In the second episode of Super Freakin' Parody Rangers:
The Green Ranger: Why should you be in charge? Your voice still cracks.
Lord Zet: Because I'M the son of the classic bad guy! [he coughs, then speaks in a deeper voice while puffing out his "man chest"] I get to be the leader.
- The Most Epic Story Ever Told in All of Human History: Epic Fail and Ridiculously Epic Fail are both having their voices crack constantly, befitting their status as the series Epic Failures.

He loses his voice when talking to her in person, making her dad think he's giving her the silent treatment. A store clerk thinks they're harassing him because they keep accidentally yelling. Their voices get so deep that a bus driver assumes they're adult dwarves trying to get kids fair and it interrupts their Disney Acid Sequence.
- In an early episode of Avatar: The Last Airbender, the gang is bickering over who should be the leader. Sokka claims that he should, being the oldest, and Katara brushes him off, saying that it doesn't mean much since his voice still cracks. His voice cracks, as he indignantly responds that it doesn't.
- Foster's Home for Imaginary Friends: Frequently occurs with Mac, due having a then-teenage voice actor.
- In the Futurama episode "Teenage Mutant Leela's Hurdles" when the gang gets splashed by tar at the Youthanizer spa, the first sign that something is amiss is when Fry's voice starts to crack mid-sentence, it causes the elderly Professor Farnsworth to become middle-aged while the rest of the crew become teenagers.
- Gravity Falls: In "Bottomless Pit!", the first segment has Dipper tiring of getting made fun of for his squeaky "puberty voice".

- In the episode "Brotherhooves Social", Big Macintosh is in disguise as a mare named Orchard Blossom and most of the time when he's in that disguise, he affects a higher-pitched, feminine voice.

- Sweetie Belle was infamous for it, to the point of being fan-named 'Squeaky Belle'.

- The Simpsons:
- One of the minor recurring characters is the Squeaky-Voiced Teen, a pimple-faced teenage boy whose voice breaks almost continuously.
- "Homer's Triple Bypass" has a flashback where Grandpa Simpson is in a church listening to Homer, as a young boy, singing in a church choir. Homer's voice then suddenly switches from a high-pitched youthful voice to his normal deep one and his singing goes from sounding good to sounding terrible.
- "The Blunder Years" has a different take on how Homer's voice changed, when 12-year-old Homer reacts to seeing Smithers Sr.'s decaying corpse; he starts constantly screaming in his high-pitched voice, but his voice suddenly deepens during one of the screams from puberty.
- Star vs. the Forces of Evil: In "Battle for Mewni", Moon's voice drops a few octaves when she tells Star that Toffee killed her mother.
- Star Wars Rebels:
- "Stealth Strike": Ezra's voice cracks at one point while he's yelling at Chopper, just as the astromech is about to turn the gravity in the gravity well control room back on.
- You probably wouldn't expect a deep-voiced, Badass Normal recurring antagonist to be subject to this. But, as revealed in "The Honorable Ones", Agent Kallus has a tendency toward this when he's freaking out, in pain or really angry. At one point in "Through Imperial Eyes", he briefly goes up a full octave while telling off Ezra for getting himself arrested.
- Steven Universe:
- During the play in "Historical Friction", this happens a tad to Jamie while performing as Pearl.

- In "Message Received", as it becomes increasingly apparent that Yellow Diamond is Not So Stoic, she begins shouting to the point where her voice breaks.
Yellow Diamond: [to Peridot] Shut [voice cracks] your MOUTH!
- In "Change Your Mind," Yellow Diamond's voice breaks again when she's going on her Motive Rant.
- This guy got especially unlucky: Not only did his voice crack, it outright broke after it cracked, causing his register to fall from somewhere around Tenor straight down to a very hoarse Baritone, hilariously terrifying the singer and causing him to cry out for his mom!
- Voice actor Jason Ritter recounted to the audience at a Gravity Falls Comic-Con panel about the time he was a teenager and a girl he liked passed by while he was playing touch football. He wanted to impress her by shouting "Blitz!", but instead, his voice cracked horribly. The fact that he's able to replicate "Puberty Squeaks" even now is partly what landed him his role as Dipper.
- While recording Finn's voice for Adventure Time Jeremy Shada was entering puberty and his voice cracked during a session. Shada was fearful that he was going to lose his job and would have to be replaced, but to his surprise, Pendleton Ward found it funny and it became a recurring joke to have Finn's voice crack and allowed him to get older during the course of the show.
- During the recording of an Adventures in Odyssey episode, David Griffin (voice of Jimmy Barclay, one of the most prominent child characters in the show's early years) had his voice crack during the middle of recording a line (usually, a kid's voice cracking during the series usually led to a new voice of said character). However, instead of a replacement, the AIO writers even devoted an episode to Jimmy's voice changing; thus making Griffin one of the few child voice actors to be retained after going through puberty.
- The famous "Dean Scream" was one of these. At the end of a long and enthusiastic speech, 2004 presidential candidate Howard Dean let out a loud "YEAAAAAH!" The only problem: his voice broke right in the middle of the "yeah", making it sound utterly bizarre. At the event, there was a crowd cheering and shouting along with him, but just listening to Dean's mic feed, he sounds like he's screaming for no reason. The Internet, naturally, jumped on it, back when that could derail a political campaign.
