About

Bolna is an open-source orchestration layer for LLM-driven voice conversations. It chains speech-to-text, a language model and text-to-speech over websockets, and the README shows phone calls set up through Twilio or Plivo. The local setup runs as Docker services with Redis for agent and prompt data, and agents can also be built directly in Python.
