The honest brief
Hedra
Real-time Live Avatars stream lip-synced talking heads at sub-100ms latency, giving voice agents a face cheaply.
- Phoneme-accurate lip-sync from one image
- 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
- Expiring-credit pricing friction
Synthesia
The enterprise default for talking-head training video — built for L&D and comms at scale, not social-clip generation.
- 230+ avatars, custom avatar cloning
- 140+ languages from one script
- No camera, mic, or crew needed
- Strong enterprise/L&D adoption
- Avatars limited for high-emotion content
- Pricier paid tiers, minute caps
- Not for cinematic or B-roll video
