Describe how you would assess respiratory function in a motor speech exam.

• A. By observing lip movement during speech tasks
• B. By measuring maximum vowel prolongation and observing breath support during speech tasks
• C. By assessing the clarity of consonant production
• D. By recording speech in noise

Answer: (B)

In a motor speech exam, assessing respiratory function is crucial because it directly influences speech production. Maximum vowel prolongation is a traditional method used to gauge respiratory support and endurance. During this task, a clinician can observe how long an individual can sustain a vowel sound, which provides insight into their breath capacity and control. Quality of breath support can also be assessed by watching for any signs of breathlessness or imbalance in vocal intensity while the individual speaks.

This method effectively evaluates not only the strength of the respiratory system but also how it contributes to overall speech intelligibility and fluency. Observing breath support during various speech tasks aids in identifying potential deficits in respiratory function that might impact an individual's communication abilities. Such assessments play a vital role in developing effective therapeutic interventions for individuals with motor speech disorders.
