Voice Changer

Q: Is my recording uploaded?

No. Recording, decoding, effects and MP3/WAV encoding run in this browser. Audio stays in memory until you clear it or close the page. Saving a voice saves settings only.

Q: Why does my voice sound robotic or watery at extreme settings?

Large pitch and voice-size shifts move the sound far from a natural voice. Lower Style strength, keep pitch within about ±7 semitones and record in a quiet room.

Q: What does Clean up do?

It removes rumble below about 75 Hz and gently evens out loudness. Turn it off in Fine-tune for the raw effect.

Turn a recording into a deep narrator, a giant, a robot, a radio voice and more. Tap a style and hear it right away, then switch between your original and the new voice at the same moment in the clip.

Pitch moves the note. Voice size changes the tone of the throat and mouth: lower sounds bigger and fuller, higher sounds smaller and lighter.

These are audio effects built from pitch shifting, formant (voice size) shifting, filters and textures. They are not AI voice conversion or voice cloning, and they will not make you sound like a specific person. How convincing a style sounds depends on your voice and recording.

How to use the Voice Changer

Press Record and say a clear sentence, open an audio file, or use the sample voice.
Tap any style. The changed voice is prepared and plays automatically.
While it plays, switch between Original and Changed to compare the same moment. Use Style strength to make it subtler or stronger.
Open Fine-tune the voice for pitch, voice size, speed and effects. The preview updates on its own.
Choose MP3 for sharing or WAV for editing, then press Download.

Example

Use the sample voice and tap Giant. While it plays, press Original and then Changed: the pitch is nine semitones lower and the voice size is larger, but the words keep their natural timing. Set Style strength to 50% for a subtler deep voice.

Questions & answers

Can I make a woman, man, child or elderly voice?

The People group has starting points for each. They shift pitch and voice size separately, which sounds more natural than pitch alone, and the older styles add breath, grit and wobble. They are stylized effects, not AI voice conversion, and no preset can sound realistic for every speaker. Try Style strength between 60% and 100% for the most believable results.

Why does my voice sound robotic or watery at extreme settings?

Large pitch and voice-size shifts stretch the sound far from a natural voice. Lower the Style strength, keep pitch within about ±7 semitones, and record in a quiet room. Background noise and echo are shifted too, so a clean recording gives the best result.

What does Clean up do?

It removes low rumble below about 75 Hz and gently evens out loud and quiet words, so the result is easier to listen to. Turn it off in Fine-tune if you want the raw effect.

Can this change my voice in calls or games?

No. This tool changes recorded clips. It does not provide a live virtual microphone.

Why does the microphone not work?

Recording needs a current browser, a secure page (HTTPS or localhost) and microphone permission. Check the site permissions in your browser, or record with another app and open the file here.

Which file should I download?

MP3 (192 kbps) is small and plays everywhere. WAV is uncompressed 16-bit audio, best for further editing. Both include trimming and any echo or room tail.
