Johns Hopkins University 3 credits Cognitive Science
This course explores theories of speech sound generation in the human vocal system, in order to learn the relationships between discrete linguistic classes of sounds and their articulatory and acoustic manifestations. Foundations for these theories include an understanding of the anatomy employed during speech, as well as principles of airflow and pressure, which are united in the source-filter theory of speech production. As speech unfolds in time, the resulting acoustic signal is altered according to the vocal tractโs configuration, leading to characteristic acoustic manifestations for vowels and consonants. These phonetic cues, in turn, ground formal phonological representations via distinctive feature theory. The course includes a practical introduction to measurement of the acoustic correlates of speech sounds.
