About
Supertone Shift is a real-time AI voice changer from Korean voice AI company Supertone. Pick a character voice and speak: the neural conversion runs with best-in-class latency down to around 47ms and no GPU required, making it practical for live streaming, gaming lobbies, VRChat, and VTubing.
Voices can be blended with the user's own voice and tuned with pitch, dynamics, and reverb controls. It integrates with Discord, Twitch, and VRChat. A free tier unlocks 100+ voices through monthly credits, with Starter at $3.99 per month and Pro at $14.99 per month.
