Perception of Time-Compressed/Expanded Japanese Words Depends on the Number of Perceived Phonemes

To investigate the relationship between phoneme perception and word perception, the relationships between the perception point of a word or a nonword and the perception point of a phoneme were measured using lexical decision and phoneme detection tasks for time-compressed stimuli, naturally spoken stimuli, and time-expanded stimuli. The perception point of a word/nonword was revealed to have a constant relationship to the perception point of a phoneme regardless of the time-expansion rate, that is, a constant number of phonemes was perceived before the perception point of a word/nonword. The results suggest that word/nonword perception depends on phoneme perception, not on the time positions of acoustical cues. The results also support the cohort model in which a word/nonword is perceived with the sequential processing of phonemes.
