Virtually all undergraduate communication sciences and disorders programs require a course that covers acoustic phonetics. Students typically have a separate phonetics (transcription) course prior to taking the acoustic phonetics course. This paper describes a way to structure an acoustic phonetics course into two halves: a first half that focuses on the source, including basic acoustics (simple harmonic motion, harmonics), vocal fold vibration, modes of phonation, and intonation, and a second half that focuses on the filter, including resonance and tube models, vowel formants, and consonant acoustics. Thus, basic acoustic properties are interwoven with specific examples of speech-related acoustics. In addition, two projects that illustrate concepts from the two halves of the course (one on fundamental frequency and the other on vowel formants) are presented. |
