Which technique can improve vocal variety during a speech?

Improving vocal variety during a speech is essential for maintaining audience interest and enhancing the overall effectiveness of the delivery. Modulating pitch, tone, speed, and volume allows the speaker to convey emotions, emphasize key points, and maintain engagement. For example, varying pitch can express excitement or seriousness, while changing speed can create suspense or urgency. Adjusting volume can help underscore important ideas or draw the audience in for a more intimate moment. This dynamic vocal approach fosters a more engaging and memorable experience for listeners, making it a vital technique for effective speech communication.
