Abstract
This lab manual is designed to be used in the context of an introductory course in Acoustic Phonetics. It is based on the software Praat, created by Paul Boersma and David Weenink (www.praat.org), and covers measurement techniques useful for basic acoustic analysis of speech. LAB 1 is an introduction to Praat: the layout of various displays and the basic functions. LAB 2 focuses on voice onset time (VOT), an important cue in identifying stop consonants. The next several labs guide students through taking acoustic measurements typically relevant for vowels (LAB 3 and LAB 4), obstruents (LAB 4) and sonorants (LAB 6 and LAB 7). LAB 8 discusses ways of measuring phonation. LAB 9 focuses on stress, pitch-accent, and tone. LAB 9 and LAB 10 bring together the material from previous labs in an exploration of cross-dialectal (LAB 10) and cross-linguistic (LAB 9) differences in speech. Finally, LAB 11 introduces speech manipulation and synthesis techniques.
Each lab includes a list of sound files for you to record, and on which you will run your analysis. If you are unable to generate good-quality recordings, you may also access pre-recorded files. Each lab also includes a set of questions designed to ensure that you – the user – understand the measurements taken as well as the values obtained for these measurements. These questions are repeated in the report at the end of the lab, which can serve as a way of recapitulating the content of the lab. The lab manual is a work in constant progress.
