The existence of multiple information carriers for a single phonemic distinction is well evident in studies of auditory and visual information integration for speech perception. Given the highly non-homogeneous nature of the auditorily-represented information carriers, we are applying the same principle withinthe auditory domain. Based on psychophysical experiments we have hypothesized that firing of "ascending sequence" cells in the primary auditory cortex is a primary information carrier for LABIAL place in stop-consonant discrimination. Partial implementation of a fuzzy-logic model for the firing of these cells, combined with a model for one other, secondary, information carrier, has yielded 1% errors in discrimination of /p/ vs. /t/ or /k/ in a "E-set", Portuguese research CV database. Exactly the same partial model, applied to /b/ vs. /d/ discrimination in an American English spelled letters database (ISOLET-1) yielded just 5% errors, providing strong evidence for the role of these cells in stop consonant discrimination across languages.
