Overview

FricAJUN (Fricative Analysis Joint Understanding Network) collaborative research venture, started in January 2004, which aims to study and understand the properties of fricative speech sounds: both voiced, e.g., [v], [dh], [z], [zh] and voiceless, e.g., [f], [th], [s], [sh].

Some of our publications on the subject of fricatives include:
