The influence of perceived sexual orientation on fricative identification

Abstract

Listeners are more likely to hear a synthetic fricative ambiguous between /s/ and /integral/ as /integral/ if it is appended to a woman's voice than a man's voice [Strand and Johnson, in Natural Language Processing and Speech Technology: Results of the 3rd KONVENS Conference (Mouton de Gruyter, Berlin, 1996), pp. 14-26]. This study expanded on this finding by replicating the result with a much larger group of male and female talkers than had been examined previously, by examining whether phonetic context mediates the influence of talker sex on fricative identification, and by examining whether talkers' perceived sexual orientation influences fricative identification. Stimuli were created by pairing a synthetic nine-step /s/-/integral/ continuum with tokens of /ae k/ and /Ip/ taken from productions of shack and ship by 44 talkers whose perceived sexual orientation had been reported previously [Munson et al., J. Phonetics (in press)]. Listeners participated in a series of two-alternative sack-shack and sip-ship identification experiments. Listeners identified more /integral/ tokens for women's voices than for men's voices for both continua. Lesbian/bisexual-sounding women elicited more sack and sip responses than heterosexual-sounding women. No consistent influence of perceived sexual orientation on fricative identification was noted for men's voices. Results suggest that listeners are sensitive to the association between fricatives' center frequencies and perceived sexual orientation in women's voices, but not in men's voices.
