Scientists Build ‘Mind-Reading’ Hearing System for Noisy Environments

Participants with intracranial electrodes listened to two competing, spatially separated conversations. Their neural signals were recorded and fed into a real-time processing system. The system uses a linear regression model to reconstruct the temporal envelope of the attended speech from low-frequency (LF) and high-gamma (HF) neural features. The reconstructed envelope is then compared to the envelopes of the two conversations to determine the listener’s focus, which in turn drives the selective amplification of the attended speaker.

A team of U.S. researchers has demonstrated, for the first time in human trials, a device that reads brain signals to automatically amplify the voice a listener wants to hear -- a potential lifeline for the 430 million people worldwide with disabling hearing loss.
