description: Smallest AI builds ultra-low-latency voice infrastructure - the Waves
  text-to-speech engine (Lightning / Lightning v2 models) for realtime speech
  synthesis and instant voice cloning, plus the Atoms platform for building and
  deploying production voice agents. The Waves REST API at
  https://waves-api.smallest.ai/api/v1 generates speech with sub-100ms latency,
  supports SSE and WebSocket streaming, and exposes voice listing and cloning via
  a Bearer-authenticated interface.
