Voice change is a normal stage of puberty for boys, but it can be a bit of a mystery when it happens. The reason your son's voice occasionally cracks or sounds squeaky is due to the growth of the voice box, or larynx. How can you change your voice online? Voice morphing is possible at once, it means that if you haven’t prepared an audio file yet, it is not a problem as you can easily create a new one using a voice recorder. Press the microphone button and make your speech. After recording a message, press “Stop”.

Monster Voice Changer

This one changes your voice so it sounds sort of like a big evil troll/monster. Behind the scenes I've done some fancy stuff with oscillating signals such that it's deeper and slightly distorted (like the monster's voice box is a bit damaged or something), and then I've cleard out the high frequency parts of the signal to smooth it off.

PA Speaker Voice Changer

This one is meant to sound like a booming PA (public announcement) speaker that's very bad quality. I imagined it was from some sort of distopian authoritarian government telling its citizens what to do, but I think you could just as easily use it as if it was a PA speaker from the 50s or something. It first distorts your voice a bit and makes the signal noisy and then adds an echo effect.

Reverse Reverb Voice Changer

This one uses a 'reverse reverb' effect to essentially make your voice echo backwards. It gives your voice an eerie vibe that sounds like a ghost or spirit from a horror movie.

This voice effect simply makes it sound like you're standing in a very large room. The echo is applied using a very cool audio technique known as 'impulse response convolution'.

Alien Voice Changer

This adds a very strange wobbling effect to your voice which make it sound like an alien who has learned how to speak your language, but it struggling - it's an alien accent, if you will.

Wobbling Voice Changer

This one is fun :) It oscillates your voice between high and low pitches in a way that makes it seem like time isn't flowing consistently - something's gone wrong with reality.

Alien Voice Changer

This one sounds like a dangerous alien - perhaps one that is part robot or something.

Robot Alien Voice Changer

I got a robot alien vibe from this one when I stumbled across it. It's also a little insect-like. So maybe a robot alien insect.

Anonymous Voice Changer

We've all heard the anonymising voice effect before, and this one is similar, except it adds a slight distortion to your voice to make it more on the 'hacker' side of things. Note that this shouldn't be used for real anonymising! It's just for fun.

This effect adds some fuzz and distortion, and plays around with the frequency spectrum a bit to try and emulate the sound of an old radio.

Cymbal Voice Effect

This is a strange one. It uses 'impulse response convolution' to create an 'echo' of your voice that sounds a bit like a cymbal in a drum kit.

Dalek Voice Changer

This uses a 'ring modulator' to simulate the same electronics that were used to generate the Dalek's voice in Doctor Who. You should do try to make your voice sound like the Dalek's when you record the audio, and this effect will do the rest.

Wah-Wah Voice Effect

This adds a 'wah-wah' effect to your voice. The 'wah-wah' effect is often used in certain types of music via the use of a 'wah-wah' pedal.

Vibrato Voice Effect

This ads a steady pitch oscillation to the input audio which (if applied to singing) can make it sound like your singing with vibrato when you're not.

Demon Voice Changer

With this effect I tried to create the sense that it was an epic demon beast thing. Much like the Balrog from Lord of the Rings. It adds some fire crackling effects in the background, deepens your voice, and adds an ominous echo.

Changes your voice so it sounds like it's coming from an old and run-down school PA speaker.

This effect makes your input audio sound like it has been transmitted via an extremely noisy medium.

Sauron Voice Changer

I've tried to make this effect sound like Sauron's voice (from Lord of the Rings). He doesn't talk much in the movies, but when he does it's very deep and has a slight ominous echo.

Russian Voice Effect

This is a silly effect that chops up the audio clip into segments, reverses them, and then puts them all back together. It sounds a little like some eastern European languages.

Silly Voice Effect

This one does some funky reversing stuff that just makes the output audio sound very strange and confusing but still understandable.

ADVERTISEMENT:

Note: For some voices (Bane and Dalek, for example), you'll need to put on the correct 'accent' for the voice transformation to work properly. Basically, try to make your voice sound like the target voice, and the engine will add some effects to make it sound like the real thing. Another random tip: You'll need to talk relatively slowly if you're using any of the 'echo-ey' voices, otherwise the echos will make it hard to understand.

You can use the generated audio clips for any purpose at all (commercial usage included). There's no need to credit voicechanger.io if you don't want to. You can leave feedback here, but please note this is just a hobby project so I won't be updating the site regularly. Thanks for stopping by - I hope you find this site useful! 😄


Honk! Squeak! What the heck is that? A goose playing the trumpet? If you're going through puberty (say: PYOO-bur-tee), it could be your voice. Both boys and girls experience voice changes as they grow older, but girls' voices get only a little deeper. A boy's voice, on the other hand, may change quite a bit — from sounding like a little kid to sounding like somebody's dad!

Your Leapin' Larynx

How does this happen? The larynx (say: LAIR-inks), also known as your voice box, actually gets bigger during puberty. The larynx, located in your throat, is a tube-shaped piece of cartilage — the same stuff your ears and your nose are made from. One of its jobs is to let you talk, sing, hum, yell, laugh, and make all sorts of noises.

Voice

When a boy reaches puberty, his body begins making lots of testosterone (say: tes-TOSS-tuh-rone). The testosterone causes his larynx to grow and his vocal cords to get longer and thicker. Vocal cords are thin muscles that stretch across the larynx like rubber bands.

What Makes a Voice?

When you speak, air rushes from your lungs and makes your vocal cords vibrate, producing the sound of your voice. If you've ever plucked a small, thin rubber band, you've heard the high-pitched twang it makes when it's stretched. A thicker rubber band makes a deeper, lower-pitched twang. It's the same sort of thing with vocal cords.

Before you reach puberty, your larynx is pretty small and your vocal cords are kind of small and thin. That's why your voice is higher than an adult's. As you go through puberty, the larynx gets bigger and the vocal cords lengthen and thicken, so your voice gets deeper. As your body adjusts to this changing equipment, your voice may 'crack' or 'break.' But this process lasts only a few months. Once the larynx is finished growing, your voice won't make those unpredictable, funny noises anymore.

What About Eve's Apple?

Not only do older guys and men sound different from boys, but you can also see the difference in their necks. When the larynx grows bigger, it tilts to a different angle and part of it sticks out inside the neck. You can see it at the front of the throat. This is known as the Adam's apple.

For girls, the larynx also grows bigger but not as much as in boys, so you can't see it through a girl's skin. There is no 'Eve's apple' in a woman's neck.

Voice Your Changing Voice

Everyone's timetable is different, so some kids' voices might start to change earlier and some might start a little later. Some voices might drop gradually, whereas others might drop quickly.

If this hasn't happened to you yet, don't worry. And if you're going through this now, try not to stress too much about the funny noises you make. It can help to talk to a parent, an older sibling, or a friend who's already gone through the voice change. Before you know it, your voice will sound clear, strong, and more grown-up!
