Researchers from the University of Stirling are developing cutting-edge AI-powered glasses that could significantly improve hearing ability for individuals with hearing loss. This technology aims to address the limitations faced by traditional hearing aids, particularly in noisy and complex environments such as busy cafés, transport hubs, or workplaces.

The glasses utilize a built-in camera to monitor the speaker's lip movements, while a smartphone app employs 5G connectivity to transmit both visual and audio data to a powerful cloud server. Here, artificial intelligence isolates the target speaker's voice from background noise and transmits a cleaned-up sound back to the user's hearing aids or headphones with minimal delay. This method, known as audio-visual speech enhancement, leverages the close relationship between lip movements and speech, providing a more accurate and effective noise reduction.

This innovative approach surpasses existing noise-canceling technologies, which often struggle with overlapping voices or intricate background sounds. The project builds on a 2015 Stirling-led study and involves collaboration with Heriot-Watt University, Edinburgh Napier University, and the University of Edinburgh. Dr. Ahsan Adeel, an AI expert at Stirling, highlights the potential of this technology, emphasizing its move toward brain-inspired, biologically plausible hearing aids capable of real-time processing with high efficiency and privacy.

Despite still being in the prototype stage, initial tests with hearing aid users have shown promising results. The team is in discussions with manufacturers to reduce costs and expand accessibility, with ongoing efforts to collect diverse noise samples to refine the system. The vision is a future where such AI-enabled devices could be publicly available, offering personalized and highly effective hearing support for anyone in noisy settings.

Professor Mathini Sellathurai from Heriot-Watt underscores that this technology aims to enhance, not reinvent, hearing aids—giving users the ability to focus on specific sounds effortlessly and potentially supporting broader applications like assisting individuals in high-noise workplaces. The project represents a significant step toward biologically inspired, low-power, high-performance hearing solutions that could dramatically improve social participation for those with hearing impairments.
