Abstract

Empirical evidence and theoretical models suggest that phonetic category perception involves two stages of auditory and phonetic processing. However, few studies examined the time course of these two processing stages. With brief stop consonant segments as context stimuli, this study examined the temporal dynamics of stop consonant perception by varying the inter-stimulus interval between context and target stimuli. The results suggest that phonetic category activation of stop consonants may appear before 100 ms of processing time. Furthermore, the activation of phonetic categories resulted in contrast context effects on identifying the target stop continuum; the auditory processing of stop consonants resulted in a different context effect from those caused by phonetic category activation. The findings provide further evidence for the two-stage model of speech perception and reveal the time course of auditory and phonetic processing.
