This short video on sexy voices suggests that women with lower voices have lower estrogen levels. Sadly, too many women sound like voice #2 in the beginning of this video, and this makes sense. Many of them are manly in their demeanor and goals, so it only makes sense that they sound like men, and their estrogen count is as low as that of some of the men out there.
The advertising industry is well aware of the fact that softer, high pitched female voices are so much more attractive and than the manly voices. Thus, it’s not a coincidence that no matter how many manly sounding females are out there on all kind of business shows on CNN, NBC, etc…, the female voices in commercials are usually extremely soft and feminine.
I dare you to find a girl in FiDi, who sounds like this.
