Solving the Speech Sound Mystery with Catherine Grizzard - SLP Full Disclosure | Lyssna här

Have you ever wondered why age norms alone cannot tell you if a child needs speech therapy? Are you ready to challenge everything you thought you knew about treatment sequencing?

In this episode of SLP Full Disclosure, host Michelle sits down with her friend and school-based SLP Catherine Grizzard to explore the world of articulation and speech sound disorders. With almost 20 years of school-based experience, Catherine brings clarity and confidence to a topic that trips up even seasoned clinicians. Together, they navigate the gray areas of speech sound norms, challenge outdated therapy sequencing, and equip you with the tools to make eligibility and dismissal decisions with conviction.

Key Topics Discussed

Speech Sound Norms: Comparing Sanders (1972) and McLeod and Crowe (2020), and why no single chart should drive your eligibility decisions.
The Complexity Approach: Understanding the "waterfall" method of targeting later-developing sounds to unlock earlier sounds for free.
Auditory Discrimination: Using minimal pairs to build a child's awareness of their own sound errors.
Tongue Tie Controversies: What the latest research says about the connection (or lack thereof) between tongue ties and speech sound production.
The Post-Pandemic Rise in Severe Speech Sound Disorders: Exploring how reduced access to visible mouth movement may be shaping outcomes for our youngest learners.
Structural vs. Treatable Disorders: Recognizing when a physical difference, not a disorder, is driving a child's speech pattern.
Eligibility and Dismissal: Building the confidence to make evidence-based decisions, even when it means saying "we've done all we can."
