What is this tool?
Change a voice on your device. Turn text, an audio file or a microphone recording into a preset AI voice, clone a voice from a short reference clip (with the speaker’s consent), or apply one of 17 sound effects. Effects include robot, alien, deep, helium, chipmunk, telephone, radio, megaphone, hall reverb, cave, echo, vibrato, tremolo, distortion, bitcrusher and reverse. Tap an effect to hear it at once, compare it with the original, trim the clip and download a WAV. AI outputs are labelled as AI-generated, and nothing is uploaded.
How to Use
- Choose what to convert: typed text, an audio file, or a recording from your microphone.
- Pick an output: a preset AI voice, a custom clone from a 5 to 10 second reference clip (only your own voice or one you have permission to use), or Effects.
- Click Convert voice (Ctrl+Enter). In Effects, just tap a tile: it renders and plays at once, so you can try many effects on one recording.
- Compare Processed and Original, trim the start and end, then download a WAV file.
Frequently Asked Questions
Is my voice uploaded?
No. Everything runs in your browser. The AI models are downloaded once (about 80 MB for preset voices, 40 MB for speech recognition and 1.5 GB for cloning) and cached on your device.
What is the difference between Preset, Custom clone and Effects?
Preset and Custom clone are AI: audio is first transcribed, then spoken again by a preset voice or by a clone of a reference voice, and those downloads are labelled as AI-generated. Effects do not use AI; they process your own clip with 17 classic effects such as robot, deep, helium, telephone, radio, reverb, echo and reverse.
Can I clone someone else’s voice?
Only with their clear permission. Cloning requires you to confirm that the voice is yours or that the speaker agreed, and you must not use the result to impersonate, mislead or harass anyone.
Are the effects live?
No. Effects are applied to a clip you record or upload, which takes a second or less, so you can record once and try every effect.
