1 Study of Language COMD 2050 Chapter 5: Sounds of Language 5 basic aspects of speech production Normal speech is produced through a complex series of movements that combine: Respiration: breathing. Phonation: producing voice. Articulation: forming speech sounds by constricting the airstream with the lips and the tongue. Resonance: allowing air flow through the nose during the production of some sounds. Prosody: adding stress and rhythm to your speech. Respiration Breathing provides the energy source for speech. The vocal folds (in the larynx) are the valves that control the air flow out of the lungs. Vocal folds = Vocal chords Larynx = Voice box

2 Respiration The larynx is made of cartilage, so it feels hard like bone but the vocal folds are fleshy. They are made of muscle, collagen and membrane. The vocal folds are at the level of your Adam’s apple – top part of the larynx. The larynx is made of cartilage. The vocal folds are made of muscle, collagen and membrane. Phonation The production of a voice by the larynx. Air flowing between the moving vocal folds produces sound. Changes in the amount of air flowing through the vocal folds and the position and configuration of the vocal folds allow us to sing and talk at different pitches and loudness levels. Resonance Refers to whether air flows out of the nose. If the air flows out through the nose during speech, the sound produced is a nasal sound. If all the air goes out through the mouth, a nonnasal speech sound is produced.
