Mumbling words and slurring sounds typically relate to which issue?

Mumbling words and slurring sounds are primarily associated with issues of articulation. Articulation refers to the clarity and distinctness with which speech sounds are produced. When someone mumbles or slurs their words, it indicates that they are not effectively articulating the individual sounds, which can make speech difficult to understand. Good articulation requires precise movements of the tongue, lips, and other vocal apparatus to produce clear speech.

In contrast, regional dialects refer to variations in speech associated with specific geographic areas and may involve different vocabulary or accent but are not inherently linked to mumbling or slurring. Pronunciation deals with how words are spoken, particularly with regard to the sounds of specific words, but it does not directly encompass the clarity of speech overall. Linguistics is the broader scientific study of language and its structure, including aspects of speech, but does not target the specific issues of clarity that mumbling and slurring imply. Therefore, articulation is the most appropriate term to describe the problem associated with mumbling and slurring speech sounds.
