I played a little with the Voice Pitch Analyzer app, to see at what pitch I could read the entire "Dorian Grey" text, without taking a break during reading (not for water, either).
When I worked a little on it it, I reached a max of 299 Hz, and an average of 220 Hz. My min average was 181 Hz, my max average was 258 Hz. Which means, I am in the middle of the female range, with the high frequencies being higher than the average female range.
But I don't like the sound of my voice in this range, it sounds very metallic (I would compare it to a male tenor voice). I am sure that I could maintain this pitch, if I would work a little on it.
But my more natural voice has a max average of 237 Hz, and an average of 195 Hz. I like the sound of this voice better, it is softer, and that is the voice I have when I sing mezzo soprano. I think I will cultivate this voice level more, and work on it, to get off of that stupid male speech pattern.
Interesting is that it slowly seems to get harder for me to continuously talk in a lower pitch male voice level, which was, of course never very natural for me, but I learned how to do it. Now I have to fully unlearn it again!
