PURPOSE: To verify the applicability of favorable and neutral environment, obtained from speech data of children without language impairment, in the treatment of phonological disorder. METHODS: Six children with phonological disorder, with an average age of six years, were treated using the ABAB - Withdrawal and Multiple Probes model. The words selected for treatment contained neutral and favorable environments for the acquisition of /r/ according to gestural and generative theoretical basis studies. The therapeutic evolution was measured based on the data of the assessments carried out before, during and after the treatment, and investigated, among the contexts used, the most effective for treatment. RESULTS: The neutral environment promoted more changes in the phonological system of the subjects than the favorable environment. The data of the subjects of this study showed favorable contexts for the acquisition of /r/ in children with phonological disorders. CONCLUSION: The favorable linguistic context, based on normality data, is not applicable to children with phonological disorders. It is suggested the realization of research in the treatment of phonological disorders using the contexts proposed in this study to test their applicability.
