论文摘要
通过智能手机和智能扬声器的扩散，聪明的个人助理（IPA）使语音成为常见的互动方式。然而，由于语言覆盖范围和功能级别的不同，许多说话者使用非本地语言与IPA互动。这可能会影响非母语说话者展示的语言生产的心理工作量和模式。我们提出了一个混合设计实验，其中本机（L1）和非母语（L2）英语的人通过智能手机和智能扬声器通过IPA完成了任务。在IPA互动期间，我们发现L2扬声器的心理工作量明显更高。与我们的假设相反，在遇到错误时，我们发现L1和L2扬声器之间没有显着差异。与IPA相互作用中L2扬声器的语言生产和处理负载增加有关的这些发现是讨论的。
Through proliferation on smartphones and smart speakers, intelligent personal assistants (IPAs) have made speech a common interaction modality. Yet, due to linguistic coverage and varying levels of functionality, many speakers engage with IPAs using a non-native language. This may impact the mental workload and pattern of language production displayed by non-native speakers. We present a mixed-design experiment, wherein native (L1) and non-native (L2) English speakers completed tasks with IPAs through smartphones and smart speakers. We found significantly higher mental workload for L2 speakers during IPA interactions. Contrary to our hypotheses, we found no significant differences between L1 and L2 speakers in terms of number of turns, lexical complexity, diversity, or lexical adaptation when encountering errors. These findings are discussed in relation to language production and processing load increases for L2 speakers in IPA interaction.
