Abstract : New facts of this auditory-acoustic basis perception were discovered as listed. (1) Plosive consonants can be distinguished from fricative consonants by the peak rate of rise intensity at their onsets. (2) The acoustic characteristics that serve to identify plosive bursts and voiceless fricatives by place of articulation can be usefully described in terms of format defined by a novel algorithm. (3) A connectionist software model that examines fourteen psychophysically relevent acoustic measures can classify any acoustic segment of speech by the location of its source in the talker's vocal tract. (4) Preliminary studies of sonorant and nasal consonants have identified the putative acoustic cues for their identification by human listeners and/or machines. (5) New methods for format tracking were developed. (6) An important set of software tools were developed that allow further studies of the auditory acoustic basis of consonant perception. (7) These tools have also aided in the studies of vowels and diphthongs, whose characteristics are being elucidated under primary support from the National Institutes of Health.
