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 within the auditory domain. Based on psychophysical(More)
A metric is presented which expresses the auditory detectability of spectral peaks with bandwidths smaller than one third of a critical band, extending for 8-20 milliseconds, prior to vowel onset in stop-consonant-vowel CVs. The metric incorporates characteristics, such as strong lateral inhibition and marked non-monotonicity in amplitude-response(More)
A set of auditorily-formulated features for PLACE discrimination in stop consonants, uncovered in extensive experiments with natural and edited sounds, are now being modeled using fuzzy logic and being applied to large databases of monosyllabic and spelled letters speech sounds, in various languages, in full-band and low-pass conditions. The rationale is(More)
For some phonemic distinctions human listeners exhibit a marked cross-language capability, in that they are capable of highly correct classification in relation to sounds (like CVs or VCVs) uttered by speakers of another language. This is particularly true regarding distinctions that are perceived in a more categorical fashion, like that of 3-way PLACE(More)
