Voice is a natural mode of expression offered by modern computer-based systems. Qualitative perspectives on voice-based user experiences (voice UX) offer rich descriptions of complex interactions that numbers alone cannot fully represent. We conducted a ...

In the domain of health and well-being, proactive voice interventions have demonstrated their efficacy. However, users often encounter privacy concerns and social embarrassment due to the lack of control over these proactive interventions, especially in ...

Voice assistants (VAs) are becoming ubiquitous within daily life, residing in homes, personal smart-devices, vehicles, and many other technologies. Designed for seamless natural language interaction, VAs empower users to ask questions and execute tasks ...

Conversational AI (e.g., Google Assistant or Amazon Alexa) is present in many people’s everyday life and, at the same time, becomes more and more capable of solving more complex tasks. However, it is unclear how the growing capabilities of conversational ...

In this paper, we propose PhantomSound, a query-efficient black-box attack toward voice assistants. Existing black-box adversarial attacks on voice assistants either apply substitution models or leverage the intermediate model output to estimate the ...

Owing to increasing adoption rates of voice assistants (VAs), integrating voice commerce (VC) as a new consumer channel is among the top objectives of businesses' current voice initiatives. VC offers consumers a new way of shopping by using VAs, which ...

Older adults often have problems and difficulties with adopting technologies but the popularity of technology usage among older adults had increased significantly in recent years. Separately, Speech-Based Intelligent Personal Assistants (sIPA) or ...
