In this course, participants will learn why a lisp is rarely a developmental speech sound disorder, and they will be challenged to look beyond inconsistent articulation normative data and the traditional model when assessing and treating lisps. Orofacial myofunctional disorders will be discussed as the root of the pesky lisp and medical & structural challenges are explored. Lateral and interdental lisps will be targeted, as well as the placement of /t/, /d/, /n/, /l/, /r/, /∫/ , /t∫/ and /dз/. Participants will be provided strategies that they can immediately apply to their practice.
