Voice Changer
Record your voice (or upload a clip) and transform it — chipmunk, deep monster, robot, alien, telephone and more — then play it back and download. Everything runs in your browser; nothing is uploaded.
Record a few seconds (allow microphone access when asked) or upload an audio file, then tap an effect to hear your voice transformed. Chipmunk and Helium pitch you up, Monster pitches you down, Robot adds a metallic ring, Alien combines both, and Telephone gives that tinny phone sound. Preview, then download an MP3 or WAV. Everything is processed on your device — nothing is uploaded.
How to change your voice
- Record or upload. Click Record and allow microphone access, or upload an audio clip (MP3, WAV, M4A, OGG, FLAC).
- Tap an effect. Try Chipmunk, Helium, Monster, Robot, Alien, Telephone or Echo — you’ll hear it straight away.
- Preview and switch effects until you find the one you like.
- Download it as an MP3 or WAV, or start over with a new clip.
The voice effects
- Chipmunk & Helium — pitch your voice up for a squeaky, high-pitched sound.
- Monster — pitch it down deep for a growly, menacing voice.
- Robot — a metallic, ring-modulated robotic tone.
- Alien — pitched up with a robotic ring for an otherworldly effect.
- Telephone — the thin, band-limited sound of an old phone call.
- Echo — a cavernous echo with repeats.
What you can use it for
- Fun & memes — prank a friend or make a funny voice clip to share.
- Content & videos — a quick character voice for a video, skit or podcast bit.
- Gaming & streaming — record a disguised or character voice for clips.
