Maybe but mostly all do
When a boy begins puberty, his voice will lower. There is no significant difference or change in voice for girls.
If you are a boy, yes.
for a boy his voice gets lower. for a girl her voice also gets lower Boys voices may change gently or suddenly during Puberty, some not at all. The larynx grows longer and stretches the muscles in the throat causing the voice to go lower in tone.
At puberty the effects of testosterone cause the Larynx (also called the Voice Box or Adam's Apple) to enlarge, this makes the pitch of the voice lower and a boy's voice is said to "break".
Yes,it is normal as you do,Puberty is like changes your voice.
You have to wait... It will happen eventually although it is not unknown for it to happen this early in Puberty. It is normal for a boy of your age to have a higher voice than older boys. Puberty will cause your voice to lower, but it can take a few years.
Testosterone is the predominant hormone in puberty in males, including deepening of the voice.
Testosterone.
Testosterone.
Usually once a boy's voice starts changing it only takes a few months to stop breaking.
I am not sure what you are asking here, are you wondering how you can tell if a voice (for example, over the phone) is a boy's voice or a girl's voice or are you enquiring about a boy's voice changing in pitch (breaking) during puberty?
'Voice breaking'.
