Abstract: The aim of the present study was to identify the effectiveness of the traditional approach to speech therapy in children with functional speech-sound disorders. Four preschool-aged children with functional articulation disorders received a three-month traditional intervention program with one-hour sessions twice a week. Evaluation of speech-sounds was presented pre- and post-therapy. Data analysis revealed that the traditional therapeutic approach is effective for this age group. Overall, all four children demonstrated an improvement in phoneme accuracy.
