| Abstract | Two experiments with a total of 17 university students and research institute staffers studied the discriminability of intensity differences carried on formant transitions in speech stimuli which varied in extent and duration. Results indicate that the relative inability to discriminate intensity differences carried on the formant transitions of consonant/vowel syllables as compared to those carried on steady-state vowel syllables, is an effect that is psychoacoustic rather than phonetic. However, these results and others suggest that simple peripheral backward masking is not a likely cause; instead, recognition masking may be involved. Moreover, the finding that phonetic-like processes occur elsewhere in audition does not necessarily impugn the existence of a speech processor; phonemic and phonological processes remain, as yet, unmatched. |
