Your voice betrays your personality in a split second - life - 14 March 2014 - New Scientist:
"You had me at "Hello"!
It turns out our opening words speak volumes – people take less than a second to form an impression of someone's personality based on their voice alone.
We know that our voices can transmit subtle signals about our gender, age, even body strength and certain personality traits, but Phil McAleer at the University of Glasgow and his colleagues wondered whether we make an instant impression.
To find out, they recorded 64 people as they read a passage.
They then extracted the word "hello" and asked 320 people to rate the voices on a scale of 1 to 9 for one of 10 perceived personality traits – including trustworthiness, dominance and attractiveness.
Although it's not clear how accurate such snap judgements are, what is apparent is that we all make them, and very quickly.
"We were surprised by just how similar people's ratings were," says McAleer.
Using a scale in which 0 represents no agreement on a perceived trait and 1 reflects complete agreement, all 10 traits scored on average 0.92 – meaning most people agreed very closely to what extent each voice represented each trait."
