Previous research has proposed that phonetic variation may index affect prior to indexing other social meanings. This study explores whether the affective indexicality of vowels identified in previous studies can also be observed among deaf or hard-of-hearing speakers, in this case, speakers of Taiwan Mandarin. The results suggest that /i/ backing is invoked to signal negative affect. This study also demonstrates how assistive devices like hearing aids and cochlear implants can be considered semiotic resources. For deaf or hard-of-hearing speakers, assistive hearing devices enter into a process of bricolage with linguistic and other symbolic resources, generating new potentials for the embodiment of affect.
