What are the type of voice quality?

Voice quality can be categorized into several types, including breathy, raspy, modal, and falsetto. Breathy voice is characterized by a soft, airy tone, while raspy voice has a rough, gravelly texture. Modal voice is the normal speaking or singing voice, and falsetto refers to a higher pitch voice that is often used to reach notes above the normal range. These qualities can be influenced by factors such as technique, emotional expression, and health.
