Does anyone else have this problem?
Basically, my voice is fine at the start of the day (and for most of it). However, I know it's a bit lower by the evening - plus I'm sure I get used to talking to people that know me and don't try as hard. It's never been a problem and I haven't been called sir on the phone or otherwise in over 10 years, but I still get self-conscious about it.
I even saw a ENT the other week due to a sore throat and he said my muscles were a bit lopsided near my vocal cords, so perhaps I am straining myself. Not sure why it took over a decade though...
