WellSaid Labs

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.

WellSaid Labs publishes 4 APIs on the APIs.io network, including Clips API, Pronunciation API, Text-to-Speech API, and 1 more. Tagged areas include AI, Text to Speech, TTS, Voice, and Voiceover.

WellSaid Labs’ developer surface includes authentication, documentation, and 8 more developer resources.
