I like this post,
I have actually done some work with my voice. Low voice is a sign of strength in humans, as well as in animals. Did you ever notice how women tend to squeak when talking to men? Supposedly that makes them sound more sexy. That's all good when you're in bed with someone, but it doesn't work well at a work meeting.
I had a friend once whose voice was naturally high pitched and nobody ever took her seriously. She was constantly patronized and interrupted by her peers.
so I've learned how to lower my voice when i want to get my point across and it works miracles.
