The voice change is the result of structural changes in the larynx (voice box) under the influence of the male hormone testosterone. Voice change in the average boy begins in early puberty when a boy's testicles begin to enlarge and produce testosterone. The specific age this takes place will depend on when puberty begins, and puberty may begin any time between ages 10 years to 14 years. There is then a gradual change or deepening of voice throughout puberty. The average age for completion of voice change is between 14 and 16 years, but just as there is a significant variation in the timing of puberty so is there in voice change.
their vocal cords stretch as they age, such as when one goes through puberty
Puberty.
When a boy begins puberty, his voice will lower. There is no significant difference or change in voice for girls.

To answer your question, yes, some girl's voices do break. Whilst going through puberty, girl's voices change in tone, causing some to 'break'. This is not, however, as dramatic and obvious as in males. Voices change because the larynx, or voice box, increases in size during puberty. When the larynx grows very quickly, it can cause the voice to 'break', crack, and squeak. As the vocal cords in the larynx get thicker and longer, the tone of the voice deepens.
Puberty goes on until age 18-20 and does not grow after puberty. It will change because of age but not grow.
