Ling 600.01 Phonetic Theory
We will do this lab in the second class meeting of Week 10. So prepare the first part of your report for that day. The final report on this lab should be submitted as an appendix to your writeup of take-home exercise 5 on Korean Stops.
Look at the three files HPHI3.WAV, LPI4.WAV, and HPPI10.WAV for the Korean Stops exercise, and practice marking the stop release and the onset of voicing in each of them. Use this practice as a way to think about how to frame your questions about the phonation type contrasts in your field project language. For example, do the spectral patterns that you see between the release of the stop and the onset of modal voicing in the following vowel in one or another of the plosive types in your FPL look more like the tense, the lax, or the aspirated stop in Korean?
You should still be eliciting wordforms that will make it possible for you to complete report 5 ("Complete consonant chart"). Organize forms for more of the consonant chart, making sure that you now have all of the rows that you will need to list all of the language's obstruents -- i.e., for all fricative(s), affricate(s), and stops made with all contrasting phonation types. Update the rows for the obstruents with information that you have figured out since Lab 8 and also now fill in the row(s) justifying any phonation type contrasts that you think are relevant for describing the language's obstruents. Organize your questions about the transcriptions of the phonation type contrasts into a list with the most pressing ones at the top. Bring to class a brief write-up of the two or three questions at the top your list, along with recordings of wordforms that you think might help you answer these questions. Try to formulate specific questions about what your transcriptions predict about differences in such measures as voice onset time, closure duration, and H1-H2 (a spectral tilt measure) in spectra over windows at the beginning and/or end of adjacent vowel(s).
