Hi,
I've been wondering if you had an advice for voice endurance. I have a passing and authentic-sounding female voice. I really like it. The problem is that my job as a college professor means that I often teach for three hours straight (principally lecture). My voice is strong and clear for close to the first two hours, but by the third hour, it has become strained and takes several hours to recover. It's not that it sounds male, but just strained and icky. Are there ways of strengthening the endurance of the voice? Again, my voice is strong, but not for periods so extended. It's as if I'm fine running the 1600m, but not the 5k.
Thanks,
Jane
