Re: Stop consonant identification based on initial spectra?
You are looking for the classic papers of my former teacher, Sheila
Blumstein SE. Stevens KN. Acoustic invariance in speech production:
evidence from measurements of the spectral characteristics of stop
consonants. [Journal Article] Journal of the Acoustical Society of
America. 66(4):1001-17, 1979 Oct.
Blumstein SE. Stevens KN. Perceptual invariance and onset spectra for
stop consonants in different vowel environments. [Journal Article]

PS: I too vote we stop with the pet anecdotes and get onto the much more
interesting questions just raised by other people!

pet anecdotes (in which no one

I'm looking for a reference that reports whether or not humans can
stop consonants based on their initial spectra--before the formant
transitions to the following vowel. Secondarily (though I suppose
fundamentally), are the initial spectra (first 10 msec or however
*before* formant transitions) invariant with respect to following
Differences between voiced and unvoiced?
Background: I had been well indoctrinated in the motor theory of
perception, teaching my students the wonders of categorical perception
stop consonants despite widely varying formant transition profiles
different vowels (i.e., /di/ looks rather different than /du/ but
identify /d/ in both). A recent conference poster looking at
neurophysiological spectral representation in non-human primate
that response to spectra of stop consonants (without the following
transitions) was sufficient to distinguish and identify them. Alas, I
not get the relevant human reference and have been unable to find one in
informal search of my reference books and MEDLINE.
