Join Professor Barbara Dodd for this one hour premium webinar where she will discuss how to diagnose a SSD using the DEAP and to distinguish between childhood apraxia of speech (CAS) and other speech sound disorders (SSDs) including Inconsistent Phonological Disorder (IPD). The latest research findings using the DEAP normative and qualitative data will also be highlighted.


Speech sound disorder (SSD) often overlaps with developmental language disorder (DLD) and affects approximately 4–16% of children between 3 and 6 years. SSD is marked by developmental errors in speech production caused by articulatory and/or phonological impairment and results in significantly reduced intelligibility. These errors occur despite a well-formed oromotor tract, normal intelligence, and intact hearing, and are distinct from problems associated with mutism or stuttering (Stefanatos & Postman-Caucheteux, 2010).
