Detection and identification of speech sounds using cortical activity patterns

Highlights • New classifier uses cortical activity to locate and identify consonants in real time. • The classifier predicts the behavioral performance of rats on speech discrimination. • Rats can identify a target sound in a stream presented up to 10 syllables per second. • The temporal processing...
