Methods & Procedures: The authors draw from international theoretical and clinical research which underscore the importance of taxonomy systems in SSD. Outcomes & Results: The current papers stresses the importance of the contribution to differential diagnosis and prognosis of children with protracted speech profiles on the bases of taxonomy profiles and systems for SSD.
