The most cost-effective, highest performance AI voice agent possible today

Telephony Server is a powerful bridge that connects telephony providers (Twilio, Vonage, Plivo, etc.) with real-time communication platforms (LiveKit, Jay.so, Pipecat, etc.). It enables seamless call routing, robust metrics collection, and observability features for enhanced telephony operations.

Quickstart template to build real-time voice AI solutions using the LiveKit Agent framework with WebRTC, open-source and local or 3rd party services such as AWS, Deepgram, Groq or OpenAI. Designed for low-latency.

Useful demo applications for Deepgram Voice AI APIs, using the Rust language! 🦀

A Streamlit web app for speaker diarization and identification in audio files. Upload or record audio, transcribe conversations, and automatically segment and label speakers using reference samples. This app makes it easy to analyze multi-speaker audio, export transcripts, and identify "who spoke when" for meetings, interviews, and more.

the Typescript toolkit for ambitious voice AI apps

An AI-powered platform for preparing for mock interviews with real-time feedback and personalized questions.

Demonstrates a real-time voice agent that answers a basic support inquiry (case status) and conditionally allows escalation based on explicit decision rules. The goal is to show how voice interaction, AI reasoning, and policy-based decisioning can be cleanly separated in a minimal, easy-to-understand setup.
