What determines the individual characteristics of the voice?

We can identify a familiar person by voice, since each has its own characteristics. This is due to several factors at once. We have a voice thanks to the vocal cords. But it is different for men and women. It is very easy to tell a man from a woman by voice in most cases. But with children it is more difficult. The fact is that the features of the vocal cords change under the influence of sex hormones. Therefore, at puberty in boys, the voice breaks. If the male sex glands are removed, the voice will also change over time.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
