  title: WellSaid Labs Clips Voice Avatars API
  description: The WellSaid Labs API renders text into studio-quality AI voiceover. It exposes streaming text-to-speech (audio returned as an HTTP stream for low time-to-first-byte playback), word-level timing and subtitle rendering, asynchronous clip creation and combination, a catalog of voice avatars, and pronunciation control via replacement libraries and respelling suggestions. All requests authenticate with an X-Api-Key header. WellSaid does not currently support end-user authentication and recommends making requests from an internal or trusted source. API access is gated behind a trial API key and a business plan. Endpoints, request fields, and response shapes here are modeled from the public documentation at docs.wellsaidlabs.com and are honestly approximated where the reference does not publish a full schema.
