....perceptual weighting and phonemic awareness. 1. INTRODUCTION 1.1. Perceptual weighting Numerous studies have shown that while every speech contrast is signalled by multiple acoustic cues, listeners do not use all acoustic cues to the same extent in their identification of these contrasts [2]. Several studies of children s perception, in particular, suggest that dynamic transitional cues are more important to children than to adults in labeling certain contrasts [6, 4, 7, 1] Nittrouer and colleagues [6, 4] for example, found that when they presented adults and children (3 to ....

....consonants. The role of the auditory periphery in this case seems to be to emphasize the region of first formant information around the time of voicing onset. INTRODUCTION The categorization of speech sounds by the auditory system has been a subject of intense attention over several decades e.g. [1, 2], reflecting its importance to the scientific study of speech perception and the technological development of more human like capabilities in automatic speech recognition. In previous work [3, 4, 5, 6, 7] we have firmly established that a two stage computational model can mimic important aspects ....

....transitions are based on change in oral and or nasal constriction, in combination with change in the dimensions relevant to formant frequencies. The relationship between place of articulation in a plosive release and the following vowel played a major role in determining these equations (see Liberman, 1996). 3. The amplitudes of the six formant dimensions are based on a combination of voicing and both oral and nasal constriction. 4. The frication and burst values are determined by place of articulation. The amplitudes of these dimensions are based on current (and, for bursting, also previous) oral ....
