Why should nonspeech oral movements not be used alone to diagnose a motor speech disorder?

Which statement best describes the corticospinal tract?

During an oral mechanism examination, a clinician notices mild facial asymmetry at rest. What is the best next step?

During a sentence-level intelligibility assessment, an unfamiliar listener transcribes the sentences produced by a patient. The patient’s speech is 80% intelligible, with a speaking rate of 75 words per minute. This results in an intelligible speaking rate of approximately 60 intelligible words per minute, or one intelligible word per second. Which interpretation is most accurate?

Extra Credit (2 point): Ethan (eight-year-old son) is currently very interested in knowing about car brands and what people drive/think about their vehicles. Help me report back to him: What kind of car do you drive—or, if you do not drive, what is your usual way of getting around? Feel free to include the color or any other detail he might appreciate. I am always interested in what people’s favorite tv show or book is currently. Please provide ideas for me below:)

Why should a motor-speech examination include more than one speech task?

A patient’s conversational speech contains occasional sound distortions and articulatory groping, but performance during short, familiar phrases is relatively accurate. Which task might provide you with greater insight into this patient’s speech strengths and challenges.

Speech intelligibility is best defined as:

Your patient has difficulty initiating movement, takes small steps, and speaks softly despite relatively preserved strength. Which explanation is most appropriate?

Which task is a sequential motion rate (SMR)?
