The collection for the JASA Special Issue on Perception and Production of Sounds in the High-Frequency Range of Human Speech is now available online! Thank you to Ewa Jacewicz, Joshua M. Alexander, and Robert A. Fox for serving as Guest Editors for this Special Issue.

The frequency range audible to humans can extend from 20 Hz to 20 kHz, but only the lower portion of this range – up to 8 kHz – has been systematically explored regarding speech. Challenging the notion that extended high-frequency (EHF) information has minimal functional significance, this Special Issue presents a collection of studies investigating the acoustic and perceptual utility of EHF information above this low range. The papers are divided into five categories, including EHF hearing, EHF hearing loss, EHF in speech and speaker recognition, acoustic EHF energy in fricative sounds, and ultrasonic vocalizations in mice in relation to human hearing.
