Open Voice Changer →How to change your voice
Pick an effect
Choose a preset such as Robot, Chipmunk or Cave, then fine-tune pitch, formant, speed, echo and reverb. Press B to compare with the original.
Save it
Choose MP3, WAV or WebM and download your changed voice.
Get the best voice effects
Record close and quiet
Speak 10 to 20 cm from the microphone in a quiet room. Effects like Cave and Echo add their own space, so a dry recording works best.
Use formant for character
Pitch moves the note of your voice; formant moves its tone. Raise both for a cartoon voice, or change only the pitch to sound higher or lower and still like yourself.
Stack effects
Start from a preset and add more: a deep voice with a little reverb, a robot with echo, or a whisper in a cave.
Wear headphones for live mode
Live mode plays your changed voice as you speak. Headphones stop the speakers feeding back into the microphone.

Voice Changer FAQ
Is this voice changer free?
Yes. Change and download as many recordings as you like, with no account and no watermark.
Are my recordings uploaded?
No. Your voice is processed in your browser and never leaves your device, so it is safe for private recordings.
Which voice effects are there?
Natural, Chipmunk, Higher, Lower, Deep, Monster, Robot, Alien, Cave, Telephone, Echo, Whisper, Vibrato, Fast and Slow. Every preset can be fine-tuned with pitch, formant, speed, drive, vibrato, ring modulation, echo and reverb.
What is the difference between pitch and formant?
Pitch is the note your voice sits on. Formants are the resonances that make it sound like a person, a child or a giant. Changing pitch alone keeps your voice recognisable; moving formants with it gives cartoon and monster voices.
Can I change the speed without changing the pitch?
Yes. The Speed slider makes speech faster or slower from 0.5× to 2× while the pitch stays where you set it.
Which files can I open?
MP3, WAV, M4A, AAC, OGG, Opus, FLAC and WebM audio, and the sound of MP4, MOV and WebM videos, up to 5 minutes long.
How do I save my changed voice?
Choose MP3 for small files that play everywhere, WAV for the best quality, or WebM for the web, then press Download.
Can I change my voice live?
Yes. Put on headphones and press Start live voice: you hear the selected effect as you speak. To keep a take, record it and save it as a file.
Does it work on phones?
Yes. It works in current mobile browsers: record with the phone microphone or open a voice memo, pick an effect and download the result.
