ABSTRACT
Although the acoustics of speech mediate production and perception, few studies have examined the entire chain. English fricatives present an interesting case because they are realized by multiple cues. Previously, 20 speakers were recorded producing the eight English fricatives with six vowels. Twenty‐one cues were measured [Jongman et al., J. Acoust. Soc. Am. 108, (2000)]. Fricatives were presented (with and without the vowel) to 20 listeners for identification. Listeners were better at identifying fricatives in context (M=91%) than isolation (M=75%), and sibilants (M=94%) than nonsibilants (M=72%). Acoustic measurements were analyzed with a regression model of cue‐parsing [McMurray et al. (unpublished)]. The model approximated listeners' performance in context (M=87%). However, this was only true when speaker‐specific variance could be parsed out; significant speaker variation was observed in every cue. Thus, vowel context may aid perception by helping listeners identify the speaker. While parsing speaker and vowel from the cues was helpful, this was not true for voicing. Voicing and place cues overlapped, but knowing the voicing did not improve identification of place (and vice versa). Finally, when cue weightings based on perception and articulation were computed independently, subtle differences emerged, suggesting that perception is similar, but not isomorphic, to production
