Abstract:Extended high-frequency (EHF; 8–20 kHz) cues support speech recognition in noisy backgrounds, particularly when the masker has reduced EHF levels relative to the target. This scenario can occur in natural auditory scenes when the target talker is facing the listener, but the masker talkers are not. The EHF benefit stands in contrast to past studies that have focused on lower frequencies and presumed that EHFs play no role in speech intelligibility. Although EHF cues improve speech recognition, it is unclear ho… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
