In the context of phonation, explain pitch, volume, and rate.

Answers will vary. Important factors of phonation are pitch, volume, and rate. These factors permit us to recognize other people's voices over the phone.
a. Pitch: The highness or lowness of the voice is called pitch. Pleasant voices have medium or low pitch; however, a varied pitch pattern is desirable. The pitch of the voice rises and falls to reflect emotions; for example, fear and anger are reflected in a higher pitch; sadness, in a lower pitch. Lower pitches for both men and women are perceived as sounding more authoritative; higher pitches indicate less confidence and suggest pleading or whining.
b. Volume: The loudness of tones is referred to as volume. Generally, good voices are easily heard by everyone in the audience but are not too loud. Use variety to hold the audience's attention, emphasize words or ideas, and create a desired atmosphere.
c. Rate: The speed at which words are spoken is called rate. Never speak so quickly that the audience cannot understand your message or so slowly that they are distracted or irritated. Vary the rate with the demands of the situation. For example, speak at a slower rate when presenting a complex concept or emphasizing an important idea. Pause to add emphasis to a key point or to transition to another major section of the presentation. Speak at a faster rate when presenting less important information or when reviewing.
