Assistive speech therapy is a general term that includes assistive, adaptive, and rehabilitative techniques for people with pronunciation disorders. One of the most important and provocative characteristics of a Computer Based Speech Therapy System (CBST) is to provide real time feedback - an ability traditionally reserved for humans (i.e. Speech and Language Therapists - SLT). That is why, together with emotion recognition, automatic assessment of pronunciation quality is considered to be the key for reducing the gap between traditional and computer assisted speech therapy [1].
