Unfortunately I'd have to go with high, though I'd love to be able to say seductive! When I hear my voice played back, I think I sound 12 years old. I've worked on lowering the register and getting better control over it, with some success. Still though, when I read work back to myself, I read it silently, and am usually able to channel a voice that is very different from my own. Wish I could do so when speaking!
I have a low timbre but I am told that I use different tones ( I don't notice them) I have a telephone voice, a reassuring voice ( with clients), a performing voice ( I do a lot of presentations + teaching groups) Like Pollyannalana I used to hate to hear my voice on the answering machine when played back. I have grown a little bit confident as I did a bit of performing on stage and learnt to modulate, pitch and pause for effect. Now I record my teaching/presentations for podcasting and I could play back and pick up bad habits and practice. I would love to have a seduction voice but if I try to put it on it may sound downright cheesy! I have been told my voice sounds sexy if I've had a teensy bit cognac or a single malt!! ( a hip flask is at hand!)
