PURPOSE: to examine the roles of speech therapists at Family Health Support Centers (NASF) according to GM directive No. 154, of January 24, 2008. METHOD: data were collected through a semi-structured questionnaire applied to the speech therapists who work at NASF in the Metropolitan Region of Recife (RMR). The questionnaire is divided into two axes, one related to the profile of the speech therapists and the other one regarding the activities and organization of the work. RESULTS: it was found that 100% of those surveyed are women, who claim to have experience in low-income communities. 80% of them performed home care service and 60% reported experience in multi- or interdisciplinary work. Regarding the work process of speech therapists at NASF, it was observed that 60% had a diagnosis of the area before starting the work, confirming the agreement with the Health Family Groups (ESF) to prioritize groups. All of them claim to perform integrated actions along with ESF, NASF and social institutions, with projects and intersectoral actions to include people with disabilities in 80% of them. Among the ones surveyed, 60% prioritize actions for rehabilitation. CONCLUSION: the study on the professional profile and the work process of speech language therapists at NASF can help identify challenges in their daily routines, as well as support actions that promote changes in training and work process toward a more integral and effective care.
