Speech perception normally utilizes multiple acoustic cues in perception of specific speech sound contrast. This study investigates which acoustic cues are responsible for syllable final stop consonant voicing in English using speech and non-speech stimuli. Specifically we study vocalic duration and F1 offset frequency cues using three experimental paradigms. Two paradigms used behavioural methods and explored identification (Exp1) and discrimination (Exp2) and one an electrophysiological method to investigate the neural correlates of processing in a mismatch negativity (MMN) experiment (Exp3). In Exp1 we presented the [bot]-[bod] continuum varying either in duration or F1 cues. Exps 2 and 3 employed a 2 (Frequency: high low) x 2 (Duration (long, short) design resulting in four different versions of English non-words [bot] and [bod] and their corresponding non-speech analogues. Nine subjects participated in Exp 1 and eight in Exps 2 & 3. The findings from Exp 1 revealed that the duration cue plays an important role in British English syllable final stop voicing. Further support for this finding was revealed in Exp 3 with larger MMN amplitude for the duration cue compared with the frequency cue.
