Which aspect does voice quality NOT include?

Voice quality encompasses the characteristics that define how a person's voice sounds, which includes aspects like tempo, volume, and clarity.

Tempo refers to the speed at which someone speaks, affecting the overall delivery of the message. Volume pertains to how loud or soft the voice is, which can impact the audience's ability to hear and understand the communication. Clarity reflects how distinctly words are articulated, which is crucial for ensuring that the message is comprehensible.

Grammar, while essential for conveying clear and coherent messages in written and spoken communication, pertains more to the structure of language rather than voice characteristics. Therefore, it does not fit within the parameters of voice quality. It relates to the use of language rather than the vocal attributes that influence how a message is presented and received.
