Tests of speech perception abilities

Tests of speech perception abilities are used to evaluate and monitor the effects of hearing loss on communicative abilities, to evaluate the effectiveness of hearing aids and implantable aids, and to assess auditory processing. The literature published over the past year addresses (1) development of new tests; (2) procedures to improve efficiency, sensitivity, and ecologic validity of speech perception tests; (3) research on the effects of lexical factors in speech recognition; and (4) assembly and evaluation of speech perception test batteries to better describe the impact of unilateral hearing loss on speech perception abilities and to assess the benefit from hearing aids and cochlear implants.
