摘要：We developed a quantitative measure, Index of Sound Error, to capture the prominent sound production deterioration in narratives produced by a woman, BYR, with Primary Progressive Aphasia. Prior studies of BYR captured semantic and morphosyntactic components of her language, but did not capture stuttering-like repetitions and sound errors. The Index of Sound Error (ISouE) has strong concurrent validity with ratings of ‘narrative goodness9 as judged by educated listeners. The ISouE is an index in our new Linguistic Communication Measure -Speech Sounds (LCM-SS), which is based on the Linguistic Communication Measure (Menn et al., 1994) and the Cantonese Linguistic Communication Measure (Kong and Law, 2004, CLCM).
