Hedra
Real-time Live Avatars stream lip-synced talking heads at sub-100ms latency, giving voice agents a face cheaply.

- Streaming avatars at ~$0.05/min
- Expressive blinks/gaze from a photo
- Multi-model access in one platform
- Maxes out at 720p
- Fewer languages than HeyGen/Synthesia
- Limited public API
