Brainstem encoding of speech in the extended high frequencies and its behavioral correlates

Year: 2025

Type: article

Abstract: This study provides the first evidence that the auditory nervous system can extract important temporal speech features ( f 0 and f 0 modulation) from the extended high-frequency (EHF) region. Individuals with EHF loss exhibit weaker neural encoding of broadband and high-frequency speech stimuli, suggesting EHF deficits broadly affect neural transduction. These results advance understanding of EHF contributions to speech processing and demonstrate that EHF hearing sensitivity is linked to neural transduction and perception of broadband speech signals.
