description: WellSaid Labs is an AI text-to-speech (TTS) platform that turns text
  into studio-quality synthetic voiceover using a library of 200+ AI voice avatars
  across many styles, languages, and accents. Beyond the AI Voice Studio web app,
  WellSaid exposes a documented REST API (base https://api.wellsaidlabs.com/v1)
  that renders text to speech, streams audio for low time-to-first-byte playback,
  returns word-level timing and subtitles, manages asynchronous clips, lists voice
  avatars, and lets teams control pronunciation with replacement libraries and
  respelling suggestions. The API authenticates with an X-Api-Key header and is
  gated behind a trial API key and a business plan.
