LINB09H3 Lecture Notes - Lecture 10: Articulatory Phonetics, Auditory Phonetics, Vocal Tract
Document Summary
What airstream is being used: acoustic phonetics. Periodicity, intensity, harmonics, resonant peaks: auditory phonetics. Recall youtube videos of buzzing source, with 3d printing of vocal tract. Filter: supralaryngeal vocal tract the shape of the tube that air travels through affects its sound. Airflow: can be ingressive or egressive, can be controlled by lungs (pulmonic), raising/lowering glottis (glotallic), mouth suction with velar and other closure (velaric) Source (several vocal fold configurations: voiceless (open), stopped (closed), modal (slightly open; vibrating normally), breathy (more open, greater airflow), creaky (less open; lower frequency) Filter: vocal tract shape, consonant place/manner, vowel height backness and rounding. Coronal: front half of tongue (dental to post-alveolar/retroflex) Sagittal cannot show progression of a segment; it shows one moment in time: affricates, taps and trills. Only have info about what"s happening in the midline lateral articulation cannot be shown. This means some categories of segments cannot be unambiguously shown on a spectrogram.
