    • ðŸšĒbackground music
  • ðŸšĒa new video editor for our video agent
  • ðŸšĒan interactive voice clone creation experience
  • ðŸšĒemotion generation for voice clones
  • ðŸšĒvoice library: better accent and emotion support, dynamically generated previews, user customizations
  • 🔧implemented observability across frontend and backend voice domain
