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
