FastRTC: The Real-Time Communication Library for Python

Hugging Face Blog · 1 year ago

FastRTC, a Python library for building real-time audio and video applications, was released to simplify development of AI applications that stream audio and video without requiring WebRTC expertise. The library includes automatic voice detection, turn-taking, a built-in Gradio UI for testing, and a free phone number feature (via fastphone()) for users with Hugging Face tokens. Developers can now build real-time LLM voice chat applications in Python with integrated speech-to-text and text-to-speech, reducing barriers to deploying conversational AI systems.
