Ok, this was a bit tough - first talk in front of about 100 people in a room designed for 200 or 300 people. 90 minutes. I definitely noticed that my voice is a bit weaker than a year ago (pre OP) but it definitely is better in respect to pitch and resonance. I need to actually go up in pitch a bit to reach the maximum volume but then it can resonate really well and project fairly good. I also did not feel strain in the throat afterwards, which is really new.
However, I noticed I have still quite some hoarseness and vocal fry that happens involuntarily. I can control it somehow if I watch out for it, but when I concentrate on my contents, I sometimes lost it and sounded hoarse and rough. I am not sure how to get this fixed. 2 more months until the 12 month healing period is officially over...
