  Despite significant improvements in automatic speech recognition and spoken
language understanding - human interaction with Virtual Personal Assistants
(VPAs) through speech remains irregular and sporadic. According to recent
studies, currently the usage of VPAs is constrained to basic tasks such as
checking facts, playing music, and obtaining weather updates.In this paper, we
present results of a survey (N = 118) that analyses usage of VPAs by frequent
and infrequent users. We investigate how usage experience, performance
expectations, and privacy concerns differ between these two groups. The results
indicate that, compared with infrequent users, frequent users of VPAs are more
satisfied with their assistants, more eager to use them in a variety of
settings, yet equally concerned about their privacy.
