Preparation for class on Tuesday, July 25, 2006

A. Vowels ==============================================

Everyone should do the following:

0) Download Praat and R (version 2.1.1) if you don't 
already have them on your laptop.

1) Look at the readme file that describes the Hillenbrand
et al. (1995) database that is available online at
http://homepages.wmich.edu/~hillenbr/voweldata.html
and figure out which set of numbers and what axes 
you want to use to plot the vowel space for some 
(possibly arbitrarily) selected speaker.

2) Download one (or more) of the three zipped together 
audio files and one (or both) of the data files from 
the URL and choose one of the speakers to look at. 
Use praat to see if you can get the same set of numbers
for the words from this speaker.  Take notes for yourself
about what you had to do to get the numbers.  (Don't 
spend more than an hour on this.)

3) Use R to make the vowel space plot that you decided 
on.  (Don't spend more than half an hour on this.)

4) Start thinking about what you would do to try to 
see whether one speaker from the group of adult men 
and one speaker from the group of adult women "have 
the same vowel space".  

5) If you want to start reading on issues in vowel 
normalization and so on, the Hillenbrand et al. 
paper would be a good place to start.  Here is the 
reference:
Hillenbrand, James, Getty, Laura A., Clark, Michael J., 
& Wheeler, Kimberlee (1995). Acoustic characteristics 
of American English vowels. Journal of the Acoustical 
Society of America, 97, 3099-3111.

In class, we'll (1) discuss the decision you made in
about numbers and axes, (2) work on a script to extract 
the numbers that you extracted in a less laborious way, 
(3) work on R code to make the plot you want to make, 
(4) begin discussing issues of vowel normalization, 
and (5) choose a reading to do on this issue.


B. L2 prosodic perception ===============================

Jeonghwa will start reading the descriptions of the Korean
and English prosodic systems on the web pages for the 
K-ToBI and AME-ToBI pages (see "Useful links") and maybe 
also the chapters on these in the Jun (2005) book.  

In class we will work on a praat script to do AME-ToBI 
labeling of some utterances that we download from the  
AME_ToBI web site.  

We will ask Soyoung to give us some stimulus from her 
work English L1 processing of English, to practice with 
our labeling script.  


C. Korean assimilation of English /tw/ versus /kw/ ======

Mira will bring some example files of English and Korean 
words with these clusters and we will begin to look at 
them in Praat to think about possibly relevant acoustic 
differences to explain the different loanword patterns.
