Which verbal technique can be effectively used to give emphasis to a speech?

Volume is a powerful verbal technique for emphasizing key points in a speech. By adjusting the loudness of one's voice, the speaker can draw the audience's attention to specific ideas or phrases. A sudden increase in volume can signify the importance of the message being conveyed, making it stand out in the listener's mind. This technique can also evoke emotional reactions and bolster the overall impact of the speech.

Using volume effectively allows a speaker to create dynamics in their speech, engaging the audience and maintaining their interest. The contrast between softer and louder segments can help highlight critical information and keep the audience focused on essential messages.
