What aspect of delivery focuses on the speaker's tone and pace while presenting?

The aspect of delivery that focuses on the speaker's tone and pace while presenting is vocal variety. This refers to the modulation of voice to enhance the presentation and maintain audience interest. It encompasses elements such as pitch, volume, tone, and pace, all of which contribute to how a message is received by listeners. Effective use of vocal variety can help emphasize key points, convey emotions, and keep the audience engaged throughout the presentation.

In contrast, body language pertains to non-verbal cues such as gestures and facial expressions that convey meaning to the audience. Audience interaction involves engaging with listeners through questions or discussions, fostering a dynamic exchange. Visual presentation, on the other hand, relates to the use of slides, charts, or other visual aids to support the spoken content. While all these elements contribute to an effective delivery, vocal variety specifically focuses on the auditory aspects of speech.
