EEG shows brain can simultaneous encode two speech streams

This article presents a study on the neural mechanisms of attention switching in multi-talker scenarios, using EEG recordings from normal-hearing adults in an immersive multi-talker environment. The study found that the processes of engaging with a new speech stream and disengaging from a previous one unfold asymmetrically, with engagement starting before disengagement is complete, and that the brain updates and uses lexical context when switching attention.
