Abstract
Native English and Spanish speakers provided identification functions for three acoustic continua: synthetic [ba]-[pa] stimuli varying in voice-onset-time (VOT), a noise-lead-time (NLT) continuum where a noise and a buzz started at different times but terminated together, and a tone-onset-time (TOT) series with a variable onset time between 500 Hz and 1500 Hz coterminous sinusoids. Onset-time differences for each continuum ranged from-35 to 55 ms. As expected, the Spanish VOT boundary was shorter than the English one. The TOT, but not the NLT, boundaries also differed between groups. Identification functions changed systimatically in shape across continua. The results show that perception of VOT by adults seems not to be causally related to the auditory temporal lag perception
