Summary

EchoKit is a fully open-source AI voice agent platform, featuring open ESP32-S3 hardware and a Rust-based server, unlike many AI devices that have closed backends. It allows users to customize automatic speech recognition (ASR), text-to-speech (TTS) with voice cloning, language model prompts, and add new actions, promoting transparency and user control. This project advances openness and privacy in AI voice technology, encouraging community contributions and innovation.

It is powered by Rust most “open” AI devices are actually closed on the backend, limiting customization and privacy. EchoKit is fully open—from ESP32-S3 hardware to the Rust-based server. You can customize ASR, TTS (including voice cloning), LLM prompts, and even add your own MCP actions. We’d love your feedback, ideas, and contributions. Try it out, check the code, and let us know what you think! Comments URL: https://news.ycombinator.com/item?id=44596016 Points: 1 # Comments: 0
