Subject: Re: AUDITORY Digest - 17 Nov 2002 to 18 Nov 2002 (#2002-197) From: Jont Allen <jba(at)auditorymodels.org> Date: Tue, 19 Nov 2002 00:21:12 -0500Dear 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: http://auditorymodels.org/jba/PAPERS/ICASSP/WCA.ps Back up on the URL, and pick a format.
