Dynamic delivery in public speaking includes:

Dynamic delivery in public speaking is characterized by engaging the audience through a combination of vocal variety and physical expressions, such as gestures and eye contact. This multifaceted approach enhances the speaker's message and helps to maintain the audience's attention.

Vocal variety refers to variations in pitch, tone, volume, and pace. This helps convey emotions and emphasize key points, making the speech more engaging and effective. A speaker who employs vocal variety can create a more dynamic experience that resonates with listeners and makes the content memorable.

In addition, gestures and eye contact play a crucial role in how a message is received. Effective gestures can emphasize points and illustrate concepts, while maintaining eye contact fosters a connection with the audience and builds trust. This non-verbal communication reinforces the spoken word and helps to keep the audience engaged.

Combining both vocal variety and physical gestures creates a richer, more dynamic speaking experience that can significantly enhance the impact of the presentation. Reading from a script, on the other hand, often leads to a more monotone delivery lacking personal engagement, which does not contribute to a dynamic presentation style. Therefore, the correct answer recognizes that both vocal variety and effective use of gestures and eye contact are essential components of dynamic delivery in public speaking.
