Pitch, rate, volume, and intensity express and evoke meaning and emotion that a verbal message cannot communicate by itself. The question arises, however, as to how much variety within the voice is desirable for the source of the message to appear most credible today in the United States. How much does the level of vocal variety affect source credibility? Does limited variability in paralinguistic cues significantly damage the perceived credibility of the source? Is it possible to have too much vocal variety in the delivery of a message?
