Maybe but mostly all do
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.
When a boy begins puberty, his voice will lower. There is no significant difference or change in voice for girls.

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?
Usually once a boy's voice starts changing it only takes a few months to stop breaking.
