based on ggwave library by Georgi Gerganov and conversational AI by ElevenLabs

How it works

• Two independent conversational ElevenLabs AI agents are prompted to chat about booking a hotel (one as a caller, one as a receptionist)
• Both agents are prompted to switch to ggwave data-over-sound protocol when they identify other side as AI, and keep speaking in english otherwise
• This repository provides API that allows agents to use the protocol

Bonus: you can open the ggwave web demo, play the video above and see all the messages decoded!

Derived work

• Norman Kirchner decoding the protocol on sound level
