Sada is an interactive multimedia program for auditory discrimination therapy in the Arabic Language. Sada was designed to extend speech therapy beyond clinical settings and provide patients with a computerbased therapy system which can be used between sessions with speech therapists; at school or at home on an 'on-demand' basis. The program provides local Arabic dialects and a configurable knowledge-base which allows for extending the therapy and customizing the pronunciation of words for different Arabic-speaking populations. The Sada architecture and its interaction design are described and the advantages of computer-based therapy for auditory perceptual problems are discussed.
