AUDIX: using Java-based software for remediating auditory perceptual deficits

Beate Grawemeyer, Richard Cox, Carmel Lum

AUDIX is a knowledge-based multimedia system for auditory discrimination exercises. Its aim is to deliver computer-based cognitive rehabilitation therapy to patients, which they can use independently at home on an on-demand basis. Specifically, it provides computer-based auditory discrimination training, intended for adults who have auditory-perceptual deficits or word sound deafness (e.g. Howard & Franklin, 88), as a result of acquired brain injury; the nature of this perceptual problem is an inability to perceive differences between phonemes in speech. A knowledge-based approach to the design of AUDIX ensures that the domain dependent therapy knowledge is separated from the system core and provides flexibility. For example, the clinician can add new knowledge (e.g. new therapy items or stimuli), or create a new knowledge base in order to provide exercises for an individual patient. This paper describes the AUDIX architecture and outlines the advantages of cognitive rehabilitation therapy over more conventional computer-therapy programs.
