You may not think about it much, but your voice says a lot about you – and not just because of the words coming out of your mouth. Here are some scientific facts about the power of the human voice……We found this in Oprah’s “O” magazine:

• When you’re attracted to someone, whether you’re a man or a woman, your voice naturally takes on “The Marilyn Effect” – as in Marilyn Monroe. Hormones start flowing through your blood and they change the amount and consistency of the mucus in the larynx. That causes both genders to become breathy when they’re in a state of attraction.
• Then, did you know that your voice gives you away when you’re tired? In fact, your voice is such a good measure of fatigue, that Japanese researchers have devised a drowsiness predictor to determine when pilots and air-traffic controllers should take breaks……and the device is based solely on their voice readings. When a person is tired, their voice gets lower, softer, and they speak more slowly.
• Speaking of speaking in Japan……They have an expression……”Talkativeness is the mouth’s way of breaking wind”.           

The Japanese are the opposite of motor-mouthed Americans. The length of a conversational pause between 2 people in a Japanese meeting is around 8 seconds. In the U.S., it’s less than one second.

• When we’re expressing affection, it’s true that women adopt a kind of baby talk. They start speaking in a higher pitch with varying tones.
• And here’s a bizarre fact about voices – the more vibrations per second in a person’s vocal frequency, the more powerful and persuasive they are. When an average person is angry, they max out at around 200 vocal vibrations per second. When Adolph Hitler gave speeches, he had 228 vibrations per second. His aggressive voice was so crucial to his power that American spies considered slipping female hormones into his food.
