Document Summary
Segments: an individual speech sound (phone) Sound is produced when air is set in motion. Speech is parasitic on breathing and eating: same equipment for speaking, breathing, eating. Three steps for producing speech: respiration, phonation, articulation. The air supply is provided by the lungs. The sound source is in the larynx (vocal folds/cords are located here) The lters are the organs above the larynx: the tube of the throat between the larynx and the oral cavity: pharynx, nasal/oral cavity, all known as the vocal tract. By vibrating the vocal folds: voiced: vibration in vocal folds, voiceless: no vibration. Can be distinguished on the basis of differences in articulation/acoustic properties. Articulatory difference: consonants: voiced or voiceless, complete closure or narrowing of vocal tract, vowels: produced with little obstruction in the vocal tract, usually voiced. Acoustic difference: vowels are more sonorous (acoustically powerful) than consonants. Syllable: a peak of sonority surrounded by less sonorous segments. Vowels form the nucleus of a syllable.
