Final answer:
Apraxia of speech (AOS) is a motor speech disorder where individuals know what they want to say but struggle with the motor formulation of words, despite having the correct word sequence.
Step-by-step explanation:
The language disturbance where the word sequence is correct, but the actual motor formulation of each word is incorrect, is known as apraxia of speech (AOS). This condition is a motor speech disorder that makes it difficult to speak. In AOS, people know exactly what they want to say, but their brains have difficulty coordinating the muscle movements necessary to say those words.
Apraxia of speech can affect individuals of all ages, but it most commonly occurs in adults who have experienced brain injury, stroke, or degenerative illnesses that affect speech and language areas. People with AOS may have trouble initiating speech, struggle with the articulation of sounds, syllables, and words, and exhibit inconsistent speech errors. They are generally able to comprehend language and know the correct order of words in sentences, which differentiates AOS from other types of speech disorders like aphasia, where language comprehension can be compromised.
Treatment typically involves speech therapy, where a speech-language pathologist (SLP) works with the individual to improve the planning, sequencing, and coordination of muscle movements for speech production.
