First Impressions

In talking about the importance of tone, I often use the example of how a person's voice sounds will often determine how engaged you will be in listening to them. This story out of NPR validates that.

. . . In less than a second, the time it takes to say "hello," we make a snap judgment about someone's personality, says Jody Kreiman, a UCLA researcher who studies how we perceive voice. On hearing just a brief utterance, we decide whether to approach the person or to avoid them. Such rapid appraisals, she says, have a long evolutionary history. It's a brain process found in all mammals.

"Things that are important for behavior and for survival tend to happen pretty fast," Kreiman says. "You don't have a huge amount of time. It has to be a simple system of communication." . . . 

This one detail of the study, the rising or falling of pitch at the end of a sentence, overlaps music:

What makes females sound more trustworthy is whether their voices rise or fall at the end of the word, says McAleer. "Probably the trustworthy female, when she drops her voice at the end, is showing a degree of certainty and so can be trusted."
