Acoustic patterns of an adolescent with multiple articulation errors

This is a case study on an adolescent who demonstrated multiple articulation errors. In particular, an acoustic analysis was performed on the same features as those investigated by Kent and Forner (1980) in children with normal articulation and by Glasson (1984) in speech- and language-disordered children. The results of the analysis were compared to the data obtained by Kent and Forner and Glasson. Our subject demonstrated longer phrase durations and more variability than any of the groups with whom he was compared. In addition, he displayed an interaction between syntactic and articulatory performance.
