Characteristics of the voice stress the femininity and/or masculinity of speakers. For instance, a woman who speaks with a high, smooth, husky, slow, and soft voice consciously or unconsciously projects another gender image than a woman who speaks with a low, rough, fast, and loud voice. Margaret Thatcher is supposed to have had speech therapy to lower her voice, in order to sound more authoritative and less feminine. Previous research shows that voice quality variation has a strong effect on the way listeners perceive the personality of speakers. Van Bezooijen (1995) studied gender associations of listeners while they were listening to voices. She found that Dutch and Japanese female speakers are perceived as shorter, weaker, more dependent, and more modest when speaking at a high pitch than when speaking at a low pitch.
It was one thing that I could not get used to in my visit there a few years ago. At one quick noodle restaurant in Tokyo there was a woman employee who sounded like a herd of cats running on chalkboards being attacked with chainsaws. :-(
In other words, it can always be worse. ;-)
Cheers,
