The development of Cantonese Lexical Neighborhood Test: a pilot study.

Objective: This study aimed at developing a theoretically driven open-set speech recognition test for pediatric clinical population of cochlear implant and/or hearing aid users, with Cantonese Chinese as their first language, to track progress in speech recognition performance as an outcome measurement of their rehabilitation.

Methods: Six monosyllabic and six disyllabic word lists were generated from the Cantonese CHILDES language database, constructed according to the Neighborhood Activation Model. There were three lexically "easy" and three lexically "hard" word lists in each sub-test, with 25 items in each list.
