How the Brain Processes Speech in Real Time

Researchers have developed a computational framework that maps how the brain processes speech during real-world conversations. Using electrocorticography (ECoG) and AI speech models, the study analyzed over 100 hours of brain activity, revealing how different regions handle sounds, speech patterns, and word meanings. The findings show that the brain processes language in a sequence—moving from thought to speech before speaking and working backward to interpret spoken words. The framework accurately predicted brain activity even for new conversations, surpassing previous models. ….[READ]
