PSY384H5 Lecture Notes - Lecture 3: Formant, Vocal Tract, Vocal Folds
Document Summary
Movement of articulators: continuous, overlap in time (co-articulated, waveforms continuous instead of discrete, speech characterized by parallel transmission, speech can encode and transmit information about multiple linguistic events in parallel. ***question: true or false: there are no silences in recordings of spoken language. Answer: false- if there is no voicing/closure gesture (stop) being produced signal will become silent. Larger vocal cords vibrate slowly(low fundamental frequency) densely packed harmonics longer vocal tracts lower formants. Female anatomy: smaller vocal cords fast vibration (high fundamental frequency) sparsely packed harmonics, shorter vocal tract higher formants. Environment: cultural, attractive if female speaks in higher pitch in certain cultures, situational, female trying to exert authority in a certain situation (business setting, surrounded by men and want to be taking seriously drop pitch. When speaker produces same vowel 2 different steady pitches, fundamental frequency and harmonics change. More vowels more careful have to be about perceiving different between f1 and f2 ratios.
