Speech sounds are produced with the participation of the following organs: 1) the lungs, 2) the respiratory throat, 3) the larynx, 4) the oral cavity, where the teeth, tongue, lips, palate (hard and soft), the palatine curtain directing the air exit through the nose or oral cavity; 5) nasal cavity.
The sound of speech is formed when the lungs exhale air. From the lungs, a stream of air flows through the larynx into the mouth or nose.
In the larynx are the vocal cords, which are two soft folds of muscle attached to the walls of the larynx, in the place where the Adam’s apple. During normal breathing, the vocal cords are relaxed and air passes freely through the larynx. The vocal cords occupy the same position in the formation of deaf consonants. If the vocal cords are close and tense, then when they pass through a narrow gap between them, air jets they tremble. This forms the voice involved in the formation of vowels, sonoric and sonorous consonants.
