Building a real-time voice AI assistant with WebRTC and LangGraph
A developer has created an open-source project called AI-RTC-Agent, designed for building real-time voice AI assistants. The system utilizes WebRTC for low-latency audio streaming and voice activity segmentation, with a decoupled architecture to prevent audio processing from being blocked. It supports dynamic switching between various LLMs and speech-to-text models, including local options like Qwen via Ollama, and implements a custom security middleware for inter-service communication.
