Parallel hierarchical encoding of linguistic representations in the human auditory cortex and recurrent automatic speech recognition systems

• Nature Machine Intelligence, Published online: 17 February 2026; doi:10.1038/s42256-026-01185-0 Keshishian, Mischler et al. • report that a recurrent automatic speech recognition system aligns closely with brain organization: model layers map to distinct cortical regions and naturally learn to encode a parallel progression from acoustic to phonetic, lexical and semantic content.
