Its Speech-to-Speech and Performance-to-Performance morphing changes a voice while retaining the speaker’s performance.

The online Voice Editor can work with Google Drive audio, while RealTime Pro routes audio through a virtual microphone to apps including Discord, Zoom, Microsoft Teams and Google Meet. The free plan includes 3 minutes per month of voice morphing and 10,000 AI tokens. Creator costs $30 a month billed annually; Professional costs $90 a month billed annually.
