A team of researchers has developed an AI system called Target Speech Hearing for noise-canceling headphones. It allows users to focus on a specific person's voice, even when all other sounds are being canceled out. The technology is currently a proof of concept but may be available in popular brands of noise-canceling earbuds and hearing aids in the future. Using a compression technique and neural networks, the system can isolate and prioritize the targeted speaker's voice, even in noisy environments. This technology has the potential to improve the user experience for noise-canceling headphones and have a significant impact on other industries.
