Boston startup AlterEgo unveiled a wearable device that allows users to communicate silently with computers, marking a significant step towards a new form of interaction with technology. This device, based on MIT research, decodes neuromuscular signals from the jaw and throat when a person internally verbalizes words. Instead of interpreting brain activity, it registers intentional motor signals, providing a safer approach to user privacy. Unlike invasive systems like Neuralink, AlterEgo utilizes machine learning to translate these signals into commands or text, which are then delivered through bone-conduction audio. This technology could empower individuals with speech impairments and facilitate communication with AI assistants in noisy environments. The system integrates existing technologies like electromyography used in prosthetics and bone-conduction audio in consumer devices, creating a discreet and practical communication tool. Public demonstration of this innovation is set for the Axios AI+ Summit on September 17, 2025, as AlterEgo seeks to differentiate itself in a competitive field dominated by major players like Neuralink and Meta.
