Investigating differences between native english and non-native english speakers in interacting with a voice user interface: a case of google home

This paper reports on findings from a pilot usability study of the Google Home Smart Speaker undertaken with native English speakers and non-native English speakers to understand the differences in usability and user experiences of the two distinct groups. The study shows that, while both user groups felt satisfied in their use of the device, native English speakers had a better user experience overall than their counterparts. Importantly, preliminary findings from the study demonstrate that cultural distinctions in English expression and system engagement may be as significant to usability as English language proficiency. The findings provide a baseline for the next stages of this research and insights for developers and researchers in the design and use of Voice User Interfaces.
