Re: AUDITORY Digest - 17 Nov 2002 to 18 Nov 2002 (#2002-197)

Dear Kala,

Phone recog. can have a zero variance when the signal to noise ratio is
good. Most
errors are due to production, not perception. The interesting question is
HOW the errors in the confusion matrix vary as a function of the SNR,
for SNR less than 30.
Look the many papers on the articulation index for the detail. As an
introduction
look at:

Back up on the URL, and pick a format.

Subject: Categorical Perception

Hi Everyone

I was asked recently what the test-retest reliabilities of categorical
perception identification and discrimination paradigms of phoneme
recognition are and i realised i dint know. I dont know if anyone has
explicitly tested the reliability. Or is it simply a population effect
and reliability is not a relevant question?

Thanks
Kala
