description: Layercode provides voice-AI agent infrastructure - low-latency voice
  pipelines that turn any LLM or text-based agent into a conversational voice agent
  for web, mobile, and phone. A REST API manages agents, sessions, and outbound
  calls, while a realtime WebSocket transport streams audio to the browser and a
  signed webhook delivers transcripts to your backend, which streams text-to-speech
  responses back over Server-Sent Events.
