Pocket TTS

Pocket TTS is a lightweight local TTS from Kyutai that runs on CPU. Offers ~200ms latency, voice cloning, and 8 built-in voices without requiring a GPU or external API.

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.
