Approximately between 4 or 5 years old, the child has already acquired all the phonemes of the Portuguese adult phonological system. However, this process does not always occur according to expectations, being noted separations/deviations in the acquisition of speech sounds. This study aimed to verify and compare the phonological evolution of, with phonological deviation submitted to phonological therapy associated with the stimulation or not of oral praxis skills. The sample was composed by six subjects (three girls and three boys) aged between 5:4 and 7:0 at the beginning of therapy. The subjects were divided in three groups, all receiving phonological therapy; to one group was added praxis stimulation of face and tongue (GFoLFa); tongue praxis stimulation (GFoL) to another and the third group was submitted only to phonological therapy (GFo). All of them were evaluated before and after therapy regarding: phonological system (Yavas, Hernandorena and Lamprecht, 1991); Orofacial Praxis Test (Bearzotti, Tavano e Fabbro, 2007) and Bucofacial Articulatory Praxis test (Hage, 2000). The results were analyzed descriptively by comparing the three groups. The results evidenced that all groups presented evolution in the phonetic inventory, the GFoLFa obtained bigger evolution in the PCC-R. At this, new ways of study applying this model are suggested, so that these results can be confirmed.
