Maybe you want a funny voice for a video, or you need to hide who's speaking in a tip or interview recording. You can change a voice right in your browser, with no software or audio gear.
When it's useful
- Fun voice effects for YouTube or TikTok
- Protecting a source or interviewee by disguising their voice
- Character voices for dubbing or skits
- Robot or radio atmosphere effects
How to do it
- Open the Voice Changer.
- Upload a file, or press Record with mic.
- Click an effect (higher, deeper, child, gruff, robot, echo, cave, radio) to hear it right away.
- Save as WAV or MP3 when you like it.
What each effect does
| Effect | What it does | Good for |
|---|---|---|
| Higher / Deeper | Shifts pitch by ±5 semitones, keeps the way you talk | Character dubbing, fun |
| Child / Gruff | Shifts pitch further, up to ±8 semitones | Exaggerated characters |
| Robot | Modulates the signal periodically (ring modulation) | Disguising who's speaking |
| Echo / Cave | Adds reverb and reflections | Atmospheric narration, sound effects |
| Radio | Narrows the frequency band and adds distortion | Old radio or walkie-talkie feel |
To disguise a voice, effects that change the tone a lot (robot, radio) work better than a simple pitch shift. Keep in mind that no effect makes a voice completely unrecognizable.
What not to do
This tool is for fun and privacy. Don't use it to impersonate or deceive anyone. It doesn't change your voice during live calls; it only works on existing files or new recordings.
Common problems
- The mic won't record: allow microphone access in your browser and reload.
- Too quiet after the effect: raise the level with Increase Volume.
- Not quite the sound you want: try each effect and compare. Effects can't be stacked.
Need captions or a transcript?
Get text with Audio to Text, or captions for video with the Subtitle Generator. Big pitch shifts can lower speech recognition accuracy, so transcribe the original first, then change the voice.
Tips for cleaner results
- Record in a quiet place so the effect doesn't distort background noise too.
- Speak a little more clearly than usual; robot and radio effects stay easier to understand.
- If the file is noisy, clean it with the Voice Noise Remover first.
- Compare effects using the same sentence each time.
Frequently asked questions
Can I change my voice during a live call?
No. Effects are applied to files and recordings, not live calls.
Can it make me sound like a completely different person?
Robot and radio change the tone a lot, but no effect makes a voice completely unrecognizable. It’s best for fun and basic disguise.
Can I both record and upload a file?
Yes, but one source is used at a time. A new mic recording replaces the current one.
Is my audio uploaded to a server?
No. All processing happens in your browser.
Which file formats can I upload?
mp3, wav, m4a and ogg, or record directly with your mic.
