I started on a very low dose at first and there were some noticeable voice changes, but nothing major. As soon as I got on half the normal dose, my voice started sounding indisputably male. That was six months after starting T. I think for most guys that start at full dose, it happens within a couple of months. The actual break, that is. The deepening seems to start within weeks.
Beard to grow. I wish. My facial hair is blond. It started growing in the mustache and goatee area after about 10 months on T, but I still couldn't grow anything that wouldn't look totally silly, and I only have to shave about once a week. That varies depending on your genetics.
I know one guy who had a decent patch of hair on his chin after only six weeks. Another had visible sideburns after a few months. I suspect I'll be a few years before I could actually grow something, if ever.
Basically, starting T is like starting puberty, and everyone's pace through it is different.
