OBJECTIVE: To investigate the relationship between the severity of speech impairment and the number of hits in the orofacial practice skills test. Presentation of clinical cases: The present study included 14 subjects of both gender, with ages ranging from 5:1 to 7:8, a previous diagnosis of speech deviations. All subjects were evaluated for the phonological system, through the Child Phonological Evaluation and also for the orofacial practice skills. For the phonological assessment subjects were divided into groups, having phonetic or phonetic-phonological, as well as the severity of the (moderate-severe, mild, moderate and mild). In the group with phonetic-phonological included seven subjects with mild severity and mild-tempered and phonological severity subjects had mild, mild-moderate and moderate-severe. The test assesses skills orofacial practice 36 items related to and orofacial praxis voiced, following movements and parallel movements. These findings indicate that the mean score of the group on tasks of phonological orofacial practice skills was higher (28 points) compared with the group with phonetic-phonological (21 points). The greatest number of hits in this group was a subject with mild deviation (35 points) and the group with phonetic also a guy with a shift light (26 hits). CONCLUSIONS: In this sample, children with speech disorders had better scores on the test of skills that child with orofacial practice phonetic, phonological, this finding suggests that the performance on tests that measure orofacial practice skills be less when the commitment refers to articulator level.
