A Clownfish alternative with AI voices
Clownfish Voice Changer has been a popular free choice on Windows for years. It applies classic effects (robot, alien, pitch shift) to your microphone across the whole system.
VoiceChange is also free, has similar effects, and adds AI voices that replace the timbre of your voice instead of filtering it. It also runs on macOS and Linux.

AI voice vs effect
An effect changes your own voice: higher, lower, metallic, echoing. An AI voice replaces your voice with another one while keeping your words and timing, so it can sound like a different person rather than a processed you. VoiceChange has both; Clownfish has effects.
When Clownfish is the better choice
- You're on an older Windows PC and only want simple effects.
- You want the change applied system-wide without selecting a microphone in each app.
- You use its built-in music player or VST plugin support.
Questions
Can I try VoiceChange without installing anything?
Yes. The effect voices run live in your browser on the home page, so you can hear them first. Discord and games need the app.
