Alleviating Linguistic and Interactional Anxiety of Non-Native Speakers in Multilingual Communication
This work addresses the overlooked issue of direct speaking support for non-native speakers in real-time multilingual communication, providing design insights for AI tools.
The paper introduces an AI tool with translation and a mutual understanding channel to reduce linguistic and interactional anxiety for non-native speakers in multilingual communication. In a study with 25 pairs, the tool improved speaking self-efficacy, reduced anxiety, and decreased workload, especially for less proficient NNSs.
Non-native speakers (NNSs) frequently encounter speaking difficulties in multilingual communication, where existing approaches have shown promise in facilitating NNSs' comprehension and participation in real-time communication. However, they often overlook providing direct speaking support, where anxiety stemming from linguistic inadequacy and uncertain communication dynamics are core issues. To address this, we introduce an AI tool with translation for real-time speaking support. It also builds a channel for mutual understanding with native speakers (NSs) to mitigate interactional anxiety. Through a within-subjects experiment involving 25 NNS-NS pairs (N = 50) on collaborative tasks, our findings suggest that the tool improved NNSs' speaking self-efficacy, reduced their interactional anxiety, and decreased their workload, particularly for NNSs with below-average language proficiency. Furthermore, NNSs reported a significant sense of support from their NS partners via the mutual understanding channel, and NSs also clearly perceived the NNSs' need for assistance and displayed a strong sense of communicative responsibility. This research underscores the potential of AI support in real-time NNS communication and the importance of promoting mutual understanding, culminating in actionable design insights for future work.
