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?
There is not an exact age for what age boys voices deepen, because we all go through puberty at a different time. Approximately, boys voices deepen around eleven through around fourteen. That still doesn't mean their voice is changed and is not going to still change, because it could still get deeper. Also, a boy's voice can change sooner or even later. I know this because there are a lot of boys in my grade (Sixth grade) I've noticed that their voice deepened.
no they cant
The kites were being flown by the boys.
The vocal cords start to stretch. The longer the cords the deeper the voice.
I'm 18 yr boy,but my voice is squeaky...
Voice breaking typically occurs in boys during puberty around the ages of 12 to 16 years old. This is when their voice deepens and becomes more mature.
A boys voice changes during Puberty. It generally gets lower in tone.
boys voices get mature by age he may have a girls voice now but not forever
This is a sign that you are done with puberty.
catch her on her time of month
he's voice changed when started singing the really high notes or his voice changed like every boys voice changes when they get older.
It depends on the boy it should be around 12-16 but there is always outlier's, when his voice starts to crack then his voice is starting to change.
