Answer:
Your voice is a bigger and more important part of your presentation than you may think. With your voice, you can mutter, whisper, or shout. You can roar, suggest, demand. You can state, announce, assert, declare, affirm.
Explanation:
Use your voice for maximum impact.
From the sound of your voice, your listeners will make judgments about your attitude toward them and the ideas you're presenting.
Vary the elements of sound for emphasis.
If the pitch, volume, rhythm, and timbre of your voice never fluctuate, you'll be speaking in a monotone.
Adjust the volume.
Use changes in volume to prevent your voice from slipping into monotonous sameness and to alert your audience to the nuances of your message.
Refine the pitch.
Pitch is the frequency of the sound waves you produce. It is about hitting high or low notes with your voice.
Alter the rhythm and tempo.
Rhythm is the pattern of the sounds you produce. Tempo is the pace of your voice.
Control the timbre.
Timbre is the emotional quality of your voice. It's the attitude behind a word or a phrase.
