Which of the following is a characteristic of Speech or Language Impairment (SLI)?

Indistinct articulation of sound is indeed a key characteristic of Speech or Language Impairment (SLI). This condition often affects an individual’s ability to produce speech sounds clearly and accurately, which can lead to difficulties in being understood by others. Those with SLI may struggle with articulating words, resulting in unclear or indistinct speech, which can impact their communication and social interactions.

In contrast, articulating words correctly indicates a proficiency in speech that would typically not be seen in individuals with SLI. Advanced language acquisition suggests a higher level of language skill and understanding, which again is not consistent with SLI. Finally, complete understanding of speech norms implies that the individual is fully aware of and can navigate the rules and nuances of language use effectively, which does not align with the challenges faced by those with speech or language impairments.
