If an individual has poor muscle control, how might it affect their speech?

When an individual has poor muscle control, particularly in the areas involved in speech production, it can significantly impact their ability to form sounds and articulate words. This reduced control often leads to unclear or slurred speech because the muscles responsible for the movements required in speaking—such as those in the lips, tongue, and throat—are not functioning optimally. This is particularly important for clear enunciation and articulation.

In contrast, other options do not directly connect with the effects of poor muscle control on speech. The inability to hear is related to auditory processing and not directly linked to muscle control. Being very loud can be a characteristic of different speech or behavioral conditions but does not indicate clarity of speech. Lastly, speaking only when spoken to is more related to social behavior or communication preferences, rather than a direct consequence of muscle control issues. Therefore, the most accurate reflection of how poor muscle control affects speech is that the person may make sounds that are not clear.
