This master’s thesis was about voice-based user interfaces, including the history of voice as an interactive medium, acceptance of the medium among users, and modern implementations of the interfaces. Initial problems of early implementations of voice-based user interfaces were about human-machine communication, as natural language of humans is ambiguous and highly interpretable, causing difficulties to machines when interpreting the given queries. Other topics of interest with the interfaces included implementing human-like cues to machines in order to make them more appealing to users, and how humans see inanimate objects when communicating with them. The problems of machines’ understanding of humans have been reduced greatly, and modern voice-based conversational virtual assistants emerged in the early 2010s. These assistants were examined: what they are, what they have achieved and what does the future hold for them. To evaluate voice as an interactive medium and the assistants, conceptual framework of six distinct paradoxes was used. Prior research, from history to today’s issues, was used to reflect against the conducted research.
