Purpose: To know the perception of the Community Health Workers (CHW) about the speech and language disorders. Methods: Cross-sectional study, which involved a questionnaire with questions related to the knowledge of CHW on speech and language disorders. The research was carried out with CHW allocated in the Centro Sanitary District of Florianopolis. Results: We interviewed 35 CHW, being mostly (80%) female gender, with a average age of 47 years (standard deviation = 2.09 years). From the total number of interviewed professionals, 57% said that they knew the work of the speech therapist, 57% believe that there is no relationship between chronic diseases and speech therapy and 97% who think the participation of Speech, Hearing and Language Sciences is important in primary care. As for capacity development, 88% of CHW claim not to have had any training performed by a speech therapist, 75% of professionals stated they had done the training Estrategia Amamenta e Alimenta Brasil, 57% of the Programa Capital Crianca and 41% of the Programa Capital Idoso. Conclusion: The knowledge of CHW about the work of a speech therapist is still limited, but the importance of speech and language disorders is recognized in primary care. The lack of knowledge, with regard to speech and language disorders, may be related to lack of qualification of the CHW in actions and/or continuing education courses that could clarify and educate these professionals to identify and better educate the population in their home visits. This study highlights the need for further research on training actions of these professionals.
