Which of the following is NOT a type of Speech Impairment?

The option identified as not being a type of speech impairment is grammar disorders. Speech impairments specifically relate to difficulties with the production of sounds and the mechanics of speaking, which include issues with articulation—how sounds are formed; fluency—how smoothly speech flows; and motor speech disorders, which involve the physical ability to produce speech sounds due to neurological or muscular function.

Grammar, on the other hand, primarily pertains to the rules and structures of language rather than the mechanics of speech production. Difficulties related to grammar fall more under the category of language disorders rather than speech impairments, as they concern how words and sentences are put together rather than the clarity or flow of spoken language. Understanding this distinction is crucial when identifying and addressing various types of communication challenges in students.
