Presenter: Pam Marshalla, MA, CCC-SLP

Course Preview:

The frontal and lateral lisps are considered mild articulation errors, yet they can be difficult to change in some clients. This seminar presents practical techniques for the remediation of the six sibilants: S, Z, Sh, Zh, Ch, and J. The class opens with normal production of these phonemes based on research in palatography, and it progresses immediately to remediation techniques. Using the evidence-based practice as a model, techniques to be discussed integrate information from the lab, the clinic, and client. These methods are derived from historic and modern texts on articulation therapy, from research data, and from the presenters own 35 years of clinical experience. Class includes lecture, slides, and small-group learning activities. Ample time for questions and discussion will be included.


Upon completion of this course, participants will be able to:

  • Identify problems of tongue mobility and stability associated with the frontal and lateral lisps.
  • Stabilize the jaw in remediation of the frontal lisp.
  • Create, narrow, and refine the midline central groove for production of the sibilants.
  • Address the individual needs of each sibilant: S, Z, Sh, Zh, Ch, and J.
  • Integrate the work of speech movement and auditory discrimination in remediation of the frontal and lateral lisps.
  • Make plans of remediation based on orthodontic problems.
  • Make remediation plans based on the age, neuromuscular considerations, and cognitive status of individual clients.
  • Transfer the responsibility of change to the client through therapy and homework activities.
