Acoustics of Voice teaches the knowledge and practical expertise necessary to enable students to: measure the acoustics of speech with computers; interpret the results; assess the Linguistic-Phonetic and Forensic-Phonetic significance of their findings. Topics include: Basic Acoustics. Acoustic Theory of Speech Production (Source-Filter Theory). Acoustics of selected speech sounds (including Tones and Intonation). Statistics. Bayes' Theorem. Between-speaker and within-speaker variation and its Forensic Application. Lectures will be supplemented by laboratory work, with students being trained in digital instrumental techniques.

Depending on how well they satisfy the requirements of the course, students will be able to:

• Digitally measure important voice acoustics, interpret the results; and assess the Linguistic- and Forensic-Phonetic significance of their findings.
• Conduct a forensic voice comparison.
• Evaluate evidence with Bayes' Theorem.

Research project (40%), 3-4 assignments (50%) and in-class test (10%).
