How to change your voice
- Record a short clip or open an audio or video file (up to 60 seconds).
- Pick a preset. Robot, Chipmunk, Deep voice, and Monster are popular starting points.
- Play the preview, then download a WAV file to use in videos, games, or messages.
Create character voices for real
Effects are fun, but voice actors build characters with their own instrument. Learn how to do a robot voice, a monster voice, or a deep voice naturally, then put it to work in a dubbing scene.
Frequently asked questions
Is this voice changer free?
Yes. Apply any effect and download the result as a WAV file. Uploading a file is unlimited; recording with your microphone follows SceneDub's free voice-recording allowance.
Does the voice changer upload my voice?
No. Effects are processed in your browser with the Web Audio API. Your recording or file never leaves your device.
Can I change my voice in real time for calls or games?
Not with this tool. It changes recordings and audio files. Real-time voice changers for calls and games need a desktop app that creates a virtual microphone.
How do I make my voice deeper?
Choose the Deep voice or Giant preset, or use Custom and lower the pitch by 5 to 7 semitones. For a natural deep voice without effects, see our guide to doing a deep voice.
