GET
List TTS Models

Overview

Lists the encodings, sample rates, containers, and controls each model supports. Use it to build a picker, validate a request before sending it, or check what a new model added. You do not choose a model — the voice you pass decides it. It comes back in the x-model header on Synthesize Speech. For one model, use GET /v2/tts/models/:id.
Prefer btts-3 or newer. expressiveness and stability are calibrated for it, and 48 kHz is the rate it renders natively. btts-2 is listed because it still synthesizes, but the controls are not tuned for it.
