A graded condition of more successful foreign-language communication achieved with AI support, observed as eased production and comprehension in a second language during AI-assisted exchanges.
Rated as communicative success in the second language with AI support, namely task completion and intelligibility on a defined L2 communication task, compared against the same task performed without AI assistance.
Proposed measurement protocol (not yet empirically validated): Within-subject contrast: rater-judged L2 communicative success (task completion plus intelligibility, 0-5) on matched tasks with vs. without AI, could be reported as the with-AI minus without-AI difference.
