I am a 15 year old boy have hit puberty with hair and all but why my voice changed yet?

There are a few possible reasons why your voice may not have changed yet, even though you have hit puberty.

* You may be a late bloomer. Some boys' voices don't change until they are 16 or even 17 years old. This is perfectly normal and you should not worry if this is the case for you.

* You may have a medical condition that is affecting your vocal cords. If you are concerned about your voice, it is important to see a doctor to rule out any underlying medical conditions.

* You may simply not be using your voice enough. Talking and singing can help to strengthen your vocal cords and encourage them to change. If you are not very talkative, you may want to try talking more often or taking singing lessons.

It is important to be patient and remember that everyone develops at their own pace. If you are concerned about your voice, talk to a doctor or your parents.
