speech perception

i.kurtzer (960214.1815)

I have to conduct a speech perception experiment for a graduate class and
would like to hear any comments.
I was hoping to determine a few parameters that would define a given
phoneme for a listener, and have access to a speech synthizer so that I
could distort different aspects of the pattern. I wonder whether I
should have the listeners all listen to the same voice or each there own,
and other such aspects. Any suggestions? feel free Avery, Martin, Rick,
or others.

much appreciated
