Dataset·Catalogue
Audio has split into separate markets: models that hold a conversation, read text aloud, transcribe, re-voice, compose and score. This catalogue tracks the current model in each family and the terms that decide whether you can build on it, from price and latency to who is allowed to clone a voice and which models are about to disappear.
Audio Models carries no numeric fields -- showing its fact columns instead, and no median footer (a median of text is not a median).
