In evaluating speech, significant pitch variation is expected from individuals without Parkinson's. True or False?

The statement is true because individuals without Parkinson's disease typically exhibit significant pitch variation in their speech. Pitch variation is a natural aspect of speech that helps convey emotion, emphasis, and meaning in communication. People generally use intonation and changes in pitch to express different ideas and feelings, making their speech more engaging and dynamic.

In contrast, individuals with Parkinson's disease often display a reduced range of pitch variation due to the motor symptoms associated with the condition. This can lead to a monotone quality in their speech, which may affect their ability to communicate effectively. Thus, recognizing the expected level of pitch variation helps in evaluating speech in individuals without Parkinson's.
