ElevenLabs TTS

ElevenLabs provides highly realistic and expressive text-to-speech voices. Supports multiple languages and voice styles.

Vision Agents uses Stream Video for real-time WebRTC transport by default. External WebRTC transports are supported as well. Most AI providers offer free tiers to get started.

ElevenLabs also provides real-time speech-to-text via Scribe with built-in turn detection. You can use both in the same agent.
