Voxta Text-to-Speech
Voice synthesis providers — turn the character's reply into spoken audio.
TTS services synthesize the character's text into spoken audio. Voxta supports cloud TTS (best quality), zero-setup local TTS (Voxta installs models automatically), and external TTS via the generic HTTP API.
Several LLM providers also offer TTS (OpenAI, NovelAI). Their TTS is documented on the LLM page since the same API key serves both — see OpenAI, NovelAI, and Voxta Cloud.
