Not very! Once a males voice has broken it is depends how low their voice is. Probably 50/50?

Im currently 7 months pregnant and since about my 4th or 5th month my voice has changed a lot. It's kind of annoying. I sound like I have a cold. When I try to speak out I always have to clear my troat first, and it is kinda low toned compared to what i sounded like before. I cant wait for my voice to get back to normal. I hope it will come back to normal!
