What is the vocal range of a 12 - 14 year old child?

The vocal range of a 12 to 14-year-old child can vary significantly, but typically, boys may have a range of about one octave, often from around A3 to A4, as they transition through their voice change. Girls in this age group usually have a range of about one and a half octaves, often from around A3 to C5. Individual differences such as physical development and vocal training can also influence their specific range.
