There is a gender difference in how anger is perceived. Yes, anger can make a woman look more powerful but there is a cost. For example, research shows that angry women are seen as less attractive. Hillary Clinton kept her anger in check. Typically her baseline voice is high and can seem strident. It was not strident or high tonight. Also look at my research on my blog about women's voices. Men hear women’s voices (higher range) in the loosely defined as the auditory brain or emotional brain. Research shows that they therefore perceive women's voices as being more emotional. Also research says that voices are not seen as authoritative.
