Subject:consonant and vowel probability ratio vs SNRFrom:Jont Allen <jba(at)auditorymodels.org>Date:Tue, 22 Oct 2002 12:38:21 -0400Dear Auditory List (and others), I am looking for some data that would help me pin down the ratio of the probability correct Pc of vowels (V) to consonants (C), as a function of the signal to noise ratio (snr), hopefully for nonsense syllables. In Fletcher's 1953 book he defines a quantity called lambda=Pc(V)/Pc(C) (page 283), which is exactly what I am looking for. While he published some detailed information on Pc(various phonemes,snr) in Chapter 18, lambda would need to be computed, and some assumptions might be necessary. Does anyone have the data, or can anyone point me a place where such data is published? This seems like a pretty basic experimental result. Thanks in advance. Jont -- Jont B.
