🤖 Patter: Open-Source Voice AI Agent SDK

Patter is an open-source voice AI SDK with a clear positioning: it serves as an alternative to managed voice services like Vapi or Retell. It allows developers to attach a real phone number to their AI agents using just a few lines of Python or TypeScript. The hard part of voice AI is often dealing with the underlying telecommunications infrastructure. Patter abstracts the integration with providers like Twilio, Telnyx, and Plivo, handling the pipeline from speech-to-text to LLM processing and real-time audio synthesis. It is a solid building block for teams that want to maintain full ownership of their voice technology stack.
