--089e0160cb98df4e8404e07fd18a Content-Type: text/plain; charset=windows-1252 Content-Transfer-Encoding: quoted-printable Stuart, Phatak and Allen (2007) looked at English consonants and a small number of vowels. That might be a good place to start. Most of the literature I know looks only at consonants (sometimes only at consonant manner & place contrasts). Phatak, S. A., and Allen, J. B. (2007), =93Consonant and vowel confusions i= n speech-weighted noise,=94 J. Acoust. Soc. Am. 121, 2312=962316. If I may add my two cents though, I think that the comparison between Cs and Vs in this situation is not exactly a fair one, since they are inherently different in intensity. Traditionally, we define SNR over the entire stimulus, but a single CVC syllable at a given SNR can be broken down into two Cs that have a much less-favorable SNR than the vowel nucleus. So, at a nominal SNR, we are actually presenting the vowel at a much more favorable SNR. That ought to account for some of the robustness of vowels in noise. On the other hand, if you=92re simply interested in which elements of the signal are robust at a given long-term SNR, none of that matters.
