In the present study a comparison is made between pathological and normal speech by means of clcctropalatography (EPG). EPG was used to document articulation in two subjects with oral motor dysfunctions, primarily affecting specific speech sounds. The subjects had normal intelligence and were presently enrolled in the public school system. The subjects' speech was recorded acoustically and dynamic EPG records of tongue-palate contacts were gathered during the production of Swedish stops and fricatives. An analysis of these patients' speech production patterns was compared to data on normal patterns of articulation for these Swedish sounds. Differences were found between normal speech and subjects regarding constriction place and constriction width for fricative sounds. The clinical evaluation regarding severity of the articulatory deviation was confirmed by a t-test between subjects, p=.0001.
