What is the term for slurred or unintelligible speech due to muscle weakness?

The term for slurred or unintelligible speech due to muscle weakness is dysarthria. This condition arises from neurological impairments that affect the muscles responsible for speech production, leading to difficulties in articulation, volume control, and clarity. Individuals with dysarthria may have speech that sounds slurred or distorted, making it challenging to communicate effectively.

In contrast, dysphagia refers to difficulties in swallowing, not speech. Enteral feeding pertains to providing nutrition through a tube inserted into the digestive system, and emphysema is a chronic respiratory condition that impacts breathing. Therefore, dysarthria is the correct choice as it specifically relates to the issues experienced in speech due to muscle weakness.
