Vocal attributes refer to the distinct characteristics of a person's voice, which can include pitch, tone, volume, and timbre. These features help to convey emotions and can influence how a message is received. For example, a higher pitch may indicate excitement, while a lower pitch can suggest seriousness. Additionally, vocal attributes can vary widely among individuals due to factors such as age, gender, and cultural background. Understanding these attributes is important in fields like speech therapy, singing, and public speaking, as they can enhance communication and expression.
