I've been meaning to ask what UWP means. I think I figured out RATE. Do tell!
I giggle a lot, and I'm frequently told I talk too fast. I can modulate my voice, as I've been doing that for years in the business world, to sound less young. At work I talk lower-- unless I'm getting up on my soapbox and passionate about a topic. In social life, I talk more girly. I feel most comfortable singing to The Carpenters (that's alto, right?) but I can also hit the high notes and sing soprano -- it's just not comfortable for long.
I was born in the midwest to midwestern parents, but grew up in the Philly area, and have been in Boston now for 19 years. Most people are thoroughly confused by my accent. No matter where I've lived, I've been told "you don't sound like you are from here."
I love it when anyone picks up on the midwestern part of it -- especially since my cousins all tell me "you talk too fast to be from the midwest." When I'm on conference calls with coworkers from Philly/NJ, I cringe and worry "do I sound like that?" And around here in Boston, nobody would ever confuse me for a local... yet my own family and friends from high school think I've picked up an accent.
I can talk in any of those three accents and fall right back into it depending on who I'm around.
