Voice Changer

Free voice changer — natural voices & fun effects

Record straight from your microphone or upload a clip, then change your voice. Pick a natural voice — deeper male, brighter female, older, younger, or a smooth radio voice — to sound like a different real person, or a fun effect like chipmunk, monster, robot or alien. Everything runs in your browser, so your recording is never uploaded — no signup, no watermark, totally private.

How does it work?

The natural voices shift your pitch while keeping your normal speaking speed (so you sound human, not sped up), and the fun effects re-pitch or reshape the audio — all using ffmpeg compiled to WebAssembly, right on your device. Press record, pick a voice, and download the result as an MP3 to share.

Can I make my voice sound like the opposite gender?

Yes — the Deep Male and Bright Femalepresets shift your pitch toward a masculine or feminine voice while keeping it sounding human. It won’t turn you into a specificperson (that needs heavy AI voice cloning), but it’s a convincing, private way to change how you sound.

Can I change the voice in a video?

Yes. Upload an MP4, MOV or WebM and the tool changes the voice while keeping the picture— it filters the audio, then muxes it straight back into your video, ready to download as an MP4. It’s perfect for TikTok, Reels, YouTube Shorts and other social media when you want to disguise your voice or add a fun character voice without losing the footage. The natural voices keep the audio perfectly in sync with the video; the fast cartoon effects (chipmunk, mouse, monster) can shift the timing.

Is it safe for kids?

Yes — there’s no account, nothing is uploaded, and the audio (or video) stays on your computer. It’s a fun, safe way for kids to play with silly voices.
