Di - You sound fantastic in either voice. As far as being able to keep it up all day, that's something that only time and continued use can help with. I've been teaching some sewing lessons recently and after talking to someone constantly for four or five hours three days in a row, I can barely speak at all in any voice! How do you do at volume? Can you yell or talk loudly and not have your voice slip?
Zeda - I think you're sounding really good! I can see where there's a little room for improvement but I think you pass just fine as you are right now.
