Project Overview

Personality is a fundamental requirement for conversational agents, such as chatbots and voice assistants, to foster connection, trust, engagement and satisfaction between humans and machines. This research aimed to address the gap in measuring user experience with LLMs that feature voice capabilities and are used as voice assistants. Additionally, it sought to explore how the personality of a voice assistant can influence trust, perceptions of authenticity, usage intentions and user engagement.
