6 Month-ish update: I haven't posted in a while, so here is what's happening to me almost 6 months out post-op. I would like to say that there's nothing new to report and progress is happening slowly, but that's not the case. In some cases, progress has regressed, but more due to my own fault than anyone else. Whenever I overuse my voice (e.g. yell something out during a busy bartending night, belt out yoga instructions over music so I can be heard, or scold my kids), it takes about a week or so to recover from it. My voice gets really raspy and almost unusable for the first day or two. It starts getting better a few days later, but then it sounds quite androgynous before it settles down and gets back to normal.
My volume is still very low. Over the phone, it's fine because phone mics amplify your voice, but in person it really is pretty hard to hear me if there is any background noise. I teach yoga with a headset now and it's unlikely I'll be able to do so without a headset from now on. As I stated previously, this is a blessing to me because my loud voice was always one of the factors that negatively impacted my voice passability.
I am a bit sad that the highest note I can reasonably sing right now is C#4 (280Hz). I can go highter, but it crackles. I can sing as low as C#3 (136Hz). My tone without placing my voice is about G3 (199Hz). Placing it I can easily sing A3 (225Hz). But that's a very limited range from what I used to be able to sing. I suppose there's still a lot of healing that needs to take place, so more time has to pass and more forced rest has to take place for me to improve.
Anyways, I'm very hopeful. My voice does sound better now than before.
On another note, has anyone tried Ingo Titze's straw intonation exercises? Will this help my new voice or should I hold off on it?
