🤖 AI Summary
This work proposes ChatLearn, an augmented AI-mediated communication system designed to address the persistent challenge of language barriers faced by non-native speakers in interactions with native speakers. Unlike existing AI tools that offer one-time assistance, ChatLearn uniquely transforms real-time conversational difficulties into contextualized learning opportunities. By leveraging natural language processing and language difficulty detection algorithms, the system dynamically delivers context-relevant review content during dialogue, integrated with a spaced repetition mechanism to support long-term retention—all while preserving communicative fluency. In a study involving 43 non-native–native speaker dyads, participants using ChatLearn demonstrated significantly improved recall of target expressions without compromising their communication experience, thereby validating the system’s effectiveness in seamlessly integrating immediate conversational support with sustained language acquisition.
📝 Abstract
Non-native speakers (NNSs) face significant language barriers in multilingual communication with native speakers (NSs). While AI-mediated communication (AIMC) tools offer efficient one-time assistance, they often overlook opportunities for NNSs'continuous language acquisition. We introduce ChatLearn, an enhanced AIMC system that leverages NNSs'communication difficulties as learning opportunities. Beyond comprehension and expression assistance, ChatLearn simultaneously captures NNSs'language challenges, and subsequently provides them with spaced review as the conversation progresses. We conducted a mixed-methods study using a communication task with 43 NNS-NS pairs, after which ChatLearn NNSs recalled significantly more expressions than the baseline group, while there was no substantial decline in communication experience. Our findings highlight the value of contextual learning in NNS-NS communication, providing a new direction for AIMC systems that foster both immediate collaboration and continuous language development.
