The same voice catalog is served on both `/v2/speak` transports — the [streaming WebSocket](/docs/flux-tts/quickstart) and [batch REST](/docs/flux-tts/batch). ## Selecting a voice Pass the model string on connection: ``` wss://api.deepgram.com/v2/speak?model=flux-haley-en ``` Every voice handles general conversational synthesis. Use the tables below to shortlist, then hear the voices live at [talk.deepgram.com](https://talk.deepgram.com) before you build. ## Featured voices Start here. The featured voices are the strongest all-rounders in the catalog — the most versatile across customer service, IVR, narration, and casual chat.
