The effects and how they work
| Effect | What it does | Good for |
|---|---|---|
| Girl / higher | Raises pitch 4 semitones and brightens the tone | Lighter, higher-sounding voice |
| Deep / boy | Lowers pitch 5 semitones and adds low end | Deeper, heavier voice |
| Chipmunk | Raises pitch 9 semitones | Jokes, memes, cartoons |
| Robot | Ring modulation at 55 Hz | Sci-fi voices, game NPCs |
| Monster | Lowers pitch 8 semitones and adds grit | Villains, horror clips |
| Echo / cave | Repeating echoes that fade out | Dramatic lines, cave sound |
| Radio / phone | Narrow band-pass with light distortion | Walkie-talkie, old phone call |
| Alien | Raises pitch and adds a fast wobble | Creature voices |
| Whisper-ish | Speech rhythm on airy noise | Spooky or secretive lines |
Pitch shifting moves the whole voice, so the girl and deep presets sound like a different person but not like a specific one. For a smaller change, use the pitch changer with one or two semitones.
Effects, not AI voice cloning
This tool applies signal-processing effects to your own recording. It does not copy anyone's voice, offer celebrity or character voices, or turn a voice into a convincing different speaker. That is also why it is fast, free and private: there is no model and no server.
A girl voice from a pitch shift is an effect; results vary with the original voice and microphone. Speak clearly and close to the microphone for the best result.
Use it on phone or computer
- iPhone or iPad: use Safari (iOS 14.5+). Recording is converted for you; downloads go to Files.
- Android: Chrome or Firefox work the same as on a computer.
- Have a video? Drop the MP4 or MOV and the voice in it is changed; you get audio back.
- Clips up to 10 minutes. Longer ones can be slow on a phone.

Frequently asked questions
Is this an AI voice changer?
No. It applies sound effects such as pitch shift, ring modulation and echo to your recording. It does not clone voices or produce celebrity voices.
Is my voice uploaded?
No. Recording, effects and export happen in your browser. You can check the Network tab in developer tools: no request carries your audio.
How do I make my voice sound like a girl?
Record a short clip, tap Girl / higher and download. It raises the pitch and brightens the tone. For a subtler result, use the pitch changer with +2 or +3 semitones.
Can I use it live in Discord or games?
No. This changes a recording after you make it. It is not a real-time microphone changer.
Does it work on iPhone?
Yes, in Safari on iOS 14.5 or later. You can record with the microphone or pick a file from Files or Photos.
Can I change the voice in a video?
You can drop an MP4 or MOV and get the changed audio back as MP3 or WAV. It does not re-export the video.
