Secondary activity connected with breathing

The Speech Mechanism


THE LUNGS*Consistency of two large sponges*Made to expand to take in air and contract to let it out*Situated with the rib cage or thorax*Function: Motor or activator that sets the passage of the air

CAVITIES OR RESONATORSAny hollow space contaning air can act as a resonator; it can change the quality of an existing sound.

THE LARYNX*Rigid structure, situated at the top of the trache and below the pharynx*It contains the first valve of trap that can interfere with the passage of the air- the vocal folds

Speech mechanism's resonators.*PHRANIX: Passage situated at the top of the larynx communicating the oral and the nasal cavities*NASAL CAVITY: Extended across the pharynx to the nostrils.*ORAL CAVITY: Is the most important resonator due to the great mobility of its organs and consequent changes of size and shape

THE VOCAL FOLDS*For normal breathing this are open forming a V-shape. *Voice sounds are produced when vocal folds are into light contact and the air make them vibrate, but if this does not happen the sound is voiceless

THE ARTICULATORS*Situated in or surroinding the oral cavity*Made up of tongue, palate, teeth and lips*The palate is a concave structure divided into: alveolar ridge, hard palate and soft palet or velum .*Tongue is the most agile speech organ. It is divided into: the tip, the blade, the front and the back.*The upper theeth are used to interfere with or stop the air-flow.*The lips constitute the mobile outer edges of the mouth and can adopt different shapes.

Made up of a series of organs and cavities
