AphasiaBank collects and analyzes samples of the discourse of individuals with aphasia and normal participants across a range of tasks. The goal of AphasiaBank is to assemble a large repository of video-recorded discourse samples, transcribed in a format that facilitates extensive computerized language analyses. This paper outlines the AphasiaBank protocol and presents core analyses of language samples from 15 normal adults and 15 individuals with aphasia using selected analyses for lexicon, morphosyntax, errors, and repetition
