Based on the child’s case history, which activity would most improve speech intelligibility: CV, VC, and CVC sequence accuracy, or other?

• A. Stabilize muscle tone to improve gross motor support of speech movement
• B. Strengthen tongue, lip, and jaw muscles
• C. Improve receptive-language ability
• D. Increase the accuracy of CV, VC, and CVC sequences

Answer: (D)

Improving speech intelligibility comes from producing sound sequences accurately and with smooth transitions. Focusing on CV, VC, and CVC sequences directly targets how well a child can articulate consonants in the context of vowels, which is essential for listeners to recognize words. When these sequences are accurate, the overall speech message becomes clearer, because the patterns the listener relies on are reliably produced.

The other approaches—trying to raise overall muscle tone for broad speech movement, increasing the strength of tongue, lip, and jaw muscles without targeting actual sequence accuracy, or improving receptive language—don't directly ensure that sounds and transitions are produced correctly. Receptive language helps understanding some of what’s said, but intelligibility hinges on how precisely the spoken output matches target sound sequences. So, practicing and improving the accuracy of CV, VC, and CVC sequences is the most effective way to boost intelligibility.
