Which of the following is a focus of articulation disorders?

Articulation disorders primarily focus on how individual speech sounds are produced. They involve issues such as distortions, substitutions, or omissions of specific sounds during speech. This means that when a person has an articulation disorder, they may not produce sounds correctly due to problems with their motor control of speech or the physical aspects of sound production.

Focusing on distortions (where a specific sound is produced incorrectly, though it may still be somewhat recognizable) and substitutions (where one sound is replaced by another, such as saying 'wabbit' instead of 'rabbit') directly relates to how articulation disorders manifest in speech. These types of errors are pivotal to understanding and addressing the client’s challenges in speech sound production.

In contrast to this, other aspects like rule-based errors or errors in multiple sound productions encompass broader issues that may involve phonological processes rather than strictly articulation. Contextual language use, while important in the broader scope of language development, does not specifically pertain to articulation disorders and is more related to how language is applied in situational contexts rather than the mechanics of producing individual sounds.
