What is the term for difficulty making certain sounds that disrupts speech clarity?

The term for difficulty making certain sounds that disrupts speech clarity is articulation disorder. This condition specifically refers to problems with the physical production of sounds, which can include issues such as substitutions (saying "thun" instead of "sun"), omissions (saying "ca" instead of "cat"), or distortions (producing sounds that are not quite correct). As a result, the speech may not be clear or understandable to listeners.

Articulation disorders are commonly addressed in speech therapy, where targeted exercises and practice can help individuals improve their speech clarity over time. This distinguishes it from other types of speech or language disorders, which focus on different aspects of communication, such as the fluency of speech or the voice's quality and pitch.
