Roblox voice changer
VoiceChange is a free desktop app that changes your voice live. Roblox voice chat listens to a microphone, so you send the new voice through the virtual microphone the app sets up.
Roblox only allows voice chat for eligible accounts that have turned it on in Roblox's settings, so check that first.
How to use a voice changer in Roblox
- Download VoiceChange free from the desktop app page (Windows, macOS on Apple Silicon, or Linux) and open it.
- Click Set up virtual mic. The app installs a free virtual microphone in one step (BlackHole on Mac, VB-CABLE on Windows, a PipeWire/PulseAudio virtual mic on Linux).
- Pick a voice and switch it on with the power button or Space. Talk and watch the trace to check it works.
- Roblox uses your computer's default microphone. On Windows, open Settings → System → Sound and set the input to CABLE Output; on a Mac, set the input to BlackHole 2ch in System Settings → Sound. Then restart Roblox.
- Talk. The people you are with hear the new voice about 25 ms after you speak, which is too short to notice.
Keep it fun
Roblox has rules about voice chat, and a voice changer doesn't change them: be kind, don't pretend to be another real person, and remember that Roblox can still moderate what you say. Switch your default microphone back when you're done so other apps use your real mic.
Questions
Is it free?
Yes. The VoiceChange desktop app and its voices are free, with no account, trial or watermark.
Will it slow down my game?
No. It uses about a quarter of one CPU core and no graphics card, so games keep their frame rate. If your computer is busy, the Steadier setting uses less CPU for 13 ms more delay.
Is my voice uploaded anywhere?
No. The AI runs on your own computer, so your audio never leaves it.
Does it work on Roblox mobile or Xbox?
No. VoiceChange runs on Windows, macOS and Linux computers only.
