At the ElevenLabs London Hackathon, developers Boris Starkov and Anton Pidkuiko introduced GibberLink, a protocol enabling AI voice assistants to recognize each other and switch from human-like speech to a more efficient data-over-sound communication using the open-source ggwave library. This innovation was aimed at optimizing AI-to-AI interactions by eliminating the inefficiencies of spoken language, thus conserving computational resources and enhancing communication speed and accuracy. The demonstration involved AI agents seamlessly transitioning to this alternative communication method during a simulated customer service interaction, showcasing the protocol's potential in real-world applications. GibberLink quickly gained attention from the tech community, with notable influencers and publications discussing its implications for future AI communications, where virtual assistants and autonomous systems might collaborate seamlessly before transmitting concise reports to human operators. The project is open-source, inviting developers to explore and integrate this novel communication method into their AI systems.
