My throat gets a little sore every now and then. I think it's within the parameters of normal. It also happened to me when my voice changed the first time at 14-ish (though that was a definite crack I was unprepared for - it got weak and squeaky and such).
Before T, I've always felt like there's been something tight in my throat stopping my voice from going as low as it should. Almost as if I'm being choked some days.
Since being on T, it's been like that tightness is subsiding. My voice hasn't had a dramatic crack, it's just been a smooth slide down. It hasn't really gotten rough or weak.
I've always spoken from the chest, it's just now (with the tightness going) I seem to have a lot more resonance - there's a vibration there now.
I thought any significant voice change in the first 4 weeks was BS - until I was on my cell in a bad reception area and got my own voice echoed back at me. It wasn't perfect, it's not "done" yet, but there was a definite change for the better
