The final step to choosing the right tone is to adjust your vocal and nonverbal cues. Vocal and nonverbal cues refer to the sounds, gestures, and expressions that you use to enhance your message. They can affect how engaging, credible, and emotional your message is. To adjust your vocal and nonverbal cues, you should pay attention to your volume, pitch, pace, and intonation. You should also pay attention to your eye contact, posture, facial expressions, and hand movements. You should use vocal and nonverbal cues that match your message and your audience's expectations. For example, if you are presenting a positive outcome, you might use a high volume, a rising pitch, a fast pace, and an upbeat intonation. You might also use eye contact, a straight posture, a smile, and open hand gestures.
Using tone to convey technical information effectively is not a one-size-fits-all approach. It requires careful planning, preparation, and practice. By following these steps, you can choose the right tone for your purpose, audience, language, style, vocal and nonverbal cues. This will help you deliver clear, accurate, and persuasive technical presentations that achieve your goals and satisfy your audience.
