Current Challenges in the Computer-Based Assessment of Speech Sound Disorders

This paper summarizes several research projects, some of which materialized as Computer-based Speech Therapy Tools (CBSTs), aiming at providing computerized solutions for the automated detection of Speech Sound Disorders. It focuses specifically on the current challenges posed by rigorous speech sound feature extraction, analysis and representation and is arguably meant to serve as a basis for the further development of a research project working towards building a dyslalia screening mobile application.
