Abstract: Through proliferation on smartphones and smart speakers, intel- ligent personal assistants (IPAs) have made speech a common in- teraction modality. Yet, due to linguistic coverage and varying lev- els of functionality, many speakers engage with IPAs using a non- native language. This may impact the mental workload and pat- tern 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 pro- cessing load increases for L2 speakers in IPA interaction.
