LIN100Y1 Lecture Notes - Lecture 2: International Phonetic Alphabet, Phonetics, Rhotic Consonant
Document Summary
A brand of linguistics that studies sounds of human speech (or the equivalent aspects of sign) Most sounds are produced when air moves out lungs (egressive airstream mechanism). The muscles responsible for forcing air out of the lungs are: The air travels from lungs up the trachea. Subglottal pressure must be sufficient to sustain vocal fold vibration. Starts with lips, then teeth, tongue, the blade, the body of the tongue, root. Lips can be rounded during the articulation of some sounds (mainly vowels, but also consonants). These articulators allow for diverse set of speech sounds (or phones). Speech involves a sequence of (sometimes coocurring) articulatory events. Some segments involve many articulatory events (or phases) that may not be synchronous. Vowels, consonants, stops, fricatives, africates, glides, liquids, nasals. Consonants are at edges of syllables (but they may also be nuclei, e. g. button, cycle, prism). Round vowels have round lips, unrounded vowels have extended lips.
