Investigating the Role of User's English Language Proficiency in Using a Voice User Interface
Aung Pyae, Paul Scifleet · 2019
Amazon's Echo, and Apple's Siri have drawn attention from different user groups; however, these existing commercial VUIs support limited language options for users including native English speakers and non-native English speakers. Also, the existing literature about usability differences between these two distinct groups is limited. Thus, in this study, we conducted a usability study of the Google Home Smart Speaker with 20 participants including native English and non-native English speakers to understand their differences in using the Google Home Smart Speaker. The findings show that compared with their counterparts, the native English speakers had better and more positive user experiences in interacting with the device. It also shows that users' English language proficiency plays an important role in interacting with VUIs. The findings from this study can create insights for VUI designers and developers for implementing multiple language options and better voice recognition algorithms in VUIs for different user groups across the world.
