As technology evolves into streamlined tasks, Voice Assistant Devices (VADs) have become increasingly valuable for office settings. This study explores the factors influencing employees’ intentions to use VADs at work using a sample of 324 respondents from India. Integrating theories from technology adoption, innovation diffusion, and trust, this study highlights that performance expectancy, compatibility and observability significantly improve attitudes toward VAD usage in professional settings. The quality of VAD outputs notably boosts user trust, emphasizing the need for high-performance devices. Employees’ receptiveness to innovation also heightens their expectations for VADs’ effectiveness. Moreover, the compatibility and visibility of VAD benefits critically shape user attitudes, directly affecting users’ willingness to adopt this technology. Our study can help organizations plan strategies for applying VADs to support workplace tasks.
