Flexible cue use in nonnative phonetic categorization

Native and nonnative listeners categorized final /v/ versus /f/ in English nonwords. Fricatives followed phonetically long (originally /v/-preceding) or short (originally /f/-preceding) vowels. Vowel duration was constant for each participant and sometimes mismatched other voicing cues. Previous results showed that English but not Dutch listeners (whose L1 has no final voicing contrast) nevertheless used the misleading vowel duration for /v/-/f/ categorization. New analyses showed that Dutch listeners did use vowel duration initially, but quickly reduced its use, whereas the English listeners used it consistently throughout the experiment. Thus, nonnative listeners adapted to the stimuli more flexibly than native listeners did.
