LINB09H3 Lecture Notes - Lecture 10: Creaky Voice, Vocal Tract, Vocal Folds
Document Summary
Lecture 10 review: articulatory structure, acoustics manner of articulation, auditory . And effects of sounds: what kind of constriction. Voicing brought apart or together by voice folds voice, voiced, voiceless. Depending on opening you can have breathiness, creaky. Acoustic: sound wave outcomes, what physical properties does wave have. Repeating pattern or chaotic noise pattern: what does signal tell us about shape of vocal tract. Periodicity - type of constriction we have. Constriction type: turbulence from fricatives is aperiodic. Vowels are louder than nasals: stops are silent. More airflow, louder sound is: decibels measure of sound pressure, total silent might be stop. Nasal sound resentence is less, airflow: upwards distance between harmonics going. Resonant peaks (formants) certain frequencies emphasized through nose, airflow obstructed a little bit. Tone and intonation: drop in f3, f1 increases, height decreases, f2i increases, backness decreases. Creating suction in mouth with velar and other closure (velaric) Negative and positive air space: sources (vocal fold)
