About

Patter connects an AI agent to the phone network through Twilio, Telnyx or Plivo. It runs the agent loop and the voice stack, and the developer chooses a provider for the LLM, speech-to-text, text-to-speech, realtime engine and carrier, in Realtime, Pipeline or Hybrid mode. It includes an automatic LLM fallback chain, tools, call transfer and guardrails, and a vendor-neutral OpenTelemetry trace of each call.

Use cases: voice-agents
