Hearing device separates simultaneous voices, amplifies the 'target' speaker

Picking out one voice from many at a crowded party is a challenge for assistive hearing devices. Now, Cong Han and colleagues have developed a new speech separation system that automatically separates audio from different speakers in a crowded environment and compares these voices to the listener’s brainwaves, so that the voice of the speaker who is the center of the listener’s attention sounds the loudest.
