چکیده

This paper discusses the automatic evaluation of speech of children with cleft lip and palate (CLP). CLP speech shows special characteristics such as hypernasality, backing, and weakening of plosives. In total five criteria were subjectively assessed by an experienced speech expert on the phone level. This subjective evaluation was used as a gold standard to train a classification system. The automatic system achieves recognition results on frame, phone, and word level of up to 75.8 % CL. On speaker level significant and high correlations between the subjective evaluation and the automatic system of up to 0.89 are obtained.
