Children with dysarthria typically struggle with what aspect of speech production?

Children with dysarthria experience challenges primarily related to the muscle control needed for speech production, which directly affects their ability to produce clear and precise phonemes. Dysarthria involves weakness or lack of coordination in the muscles used for speaking, leading to slurred or unclear speech. This can make it difficult for others to understand what the child is saying, as their articulation may be imprecise.

In contrast, creating vocabulary, understanding grammar, and expressing emotions pertain to cognitive and linguistic aspects of language rather than the mechanical processes involved in speech execution. While a child with dysarthria may indeed have rich vocabulary and comprehension skills, the primary issue lies in their physical ability to articulate words clearly. Thus, the focus on phoneme production is why the correct answer emphasizes clear and precise phonemes.
