Experts provide neural evidence for the glimpsing model of speech perception

Researchers led by Dr. Nima Mesgarani at Columbia University, US, report that the brain treats speech in a crowded room differently depending on how easy it is to hear, and whether we are focusing on it. Publishing June 6th in the open access journal PLOS Biology, the study uses a combination of neural recordings and computer modeling to show that when we follow speech that is being drowned out by louder voices, phonetic information is encoded differently than in the opposite situation. The findings could help improve hearing aids that work by isolating attended speech.
