The honest brief
Cartesia
State-space Sonic models hit sub-100ms first audio — the latency floor for real-time voice agent loops.
- Streaming over WebSocket for fast first audio
- State-space architecture, not transformer
- Streaming-first WebSocket protocol depth
- Cost-competitive at scale
- Long-form expressive texture trails ElevenLabs
- Fewer voices than ElevenLabs catalog
- API-only, no end-user app
Resemble AI
Rare in covering both sides of synthetic voice — making it and policing it — and deployable fully on-prem for regulated audio work.
- Generation + detection in one
- On-prem deployment option
- Open-source Chatterbox model
- Real-time watermarking
- Limited free tier
- Detection confidence drops on noisy audio
