Responsible use
This tool doesn't imitate celebrities or anyone else; it only adds effects to your voice. Process recordings of other people only with their permission, and don't use an altered voice to mislead anyone or to cause harm while hiding your identity.
If you'd like a digital copy of your own voice to read new scripts, see the consent-based voice cloning studio.
Privacy: your recording never leaves your device
Everything happens in your browser. Your file is not sent to Voiser's servers or stored anywhere, and it's cleared from memory when you close the tab. That's also why the tool stays fast on a slow connection.
Common questions
Does it change my voice in real time?
No. The tool applies effects to a recorded file. If you don't have a recording yet, record one with your phone's or computer's voice recorder first.
Can I make my voice sound like a celebrity?
No. This tool doesn't imitate people; it only applies sound effects such as robot, echo or telephone.
How strong can the effect be?
Each effect comes with a balanced setting and the result is normalized automatically. For finer control, change the pitch step by step with the pitch changer.
Can I add an effect to my video's audio?
Get the audio first with extract audio from video, apply the effect here, then put it back on the video in your editor.
