BACKGROUND: focus on studies conducted over the last ten years on therapy for phonological disorders. PURPOSE: to analyze the national and international studies on phonology, conducted from the year 2000, in order to check their contributions for the clinical treatments, while identifying new opportunities in research. CONCLUSION: all analyzed studies bring out contributions that can be adopted as tools for the speech clinic. The therapist should pay attention to the fact that different children respond differently to the different approaches, so that therefore, caution should be taken clinician in treatment planning. The report suggests research possibilities and aspects that could be more widely used in the scientific work. However, no studies were found indicating the average number of sessions required in order to determine the discharge in speech pathology cases, and global approaches, that could solve all the issues that may be delayed in these children, such as auditory processing, working memory, phonemic discrimination, phonological awareness and written language development.
