Flux TTS

Flux TTS Voices & Languages

The Flux TTS launch voice catalog. Every voice is a flux-{voice}-en model string served on /v2/speak over both the streaming WebSocket and batch REST transports.

Flux TTS voices use the model string format flux-{voice}-{language} (e.g. flux-haley-en). The same voice catalog is served on both /v2/speak transports — the streaming WebSocket and batch REST.

Launch catalog. These are the English voices available at launch. The catalog will expand, and multilingual voices (flux-{voice}-multi) are planned for a later release.

Selecting a voice
