Lab assignments give you hands-on practice with speech-sound analysis in Praat, experiment design, and/or data analysis and interpretation. Some lab assignments will be done in partner groups.
Lab assignments will start out smaller and become a little more complex as the semester progresses. The point values of the different lab assignments will vary accordingly.
