Vocal fold

Vocal folds are paired folds in the human larynx that participate in the formation of the glottis. The vocal cords are separated by a small lining of the larynx and are not adjacent to it. Described in 1879 by the German pathologist F. Fischer. They received their name “vocal folds” due to the fact that in the human body they play a major role in the formation of speech sounds by vibration of the vocal cords.

The vocal fold is an anatomical structure in the larynx responsible for producing the voice in humans and other animals.

The vocal fold is made up of elastic tissue that sits between the vocal folds and allows them to open and close during speech. It is covered with layers of muscles and nerves that control its movement. When the vocal folds close, the air pressure in the airways decreases, causing the pitch to change and sounds to be formed.

The human voice has many different sounds, from the vowels "a", "o", "u" to the consonants "b", "p", "k". Each sound requires a different combination of muscle contractions on the vocal folds to produce. For example, to pronounce the sound "e", the vocal folds must be open a little more than for the sound "i".

Voice research requires careful analysis of the many sounds a person makes. In addition, understanding the functioning of the vocal folds helps doctors better understand the underlying causes of voice disorders and choose the right treatment.

Nowadays, voice research is becoming more common and this is due to the development of speech recognition technologies such as smartphones and tablets. For example, users constantly record themselves and recognize their voice through a microphone. In the future, voice technology may further enhance the effectiveness of an online voice platform, where voice can be used to identify users and their personal interests.

Vocal fold **Vocal cord (vocal cord, lateral fold of the larynx, lat. plica vocalis)** - longitudinal thickening of the mucous membrane of the anterior and lateral walls of the respiratory (upper) part of the larynx at the point of their attachment to the thyroid cartilage on each side, between the vocal processes the latter. The vocal folds are dense, velvety, and consist of loose connective tissue. This organ is also the human vocal organ and allows the production of sounds of varying pitches and intensities. There are two vocal folds: left and right; They correspond to the external vocal tract, which runs along the left and right sides of the larynx.
