Method of interacting between humans and conversational voice agent systems

Area of Science:

• Human-Computer Interaction
• Artificial Intelligence
• Cognitive Science

Background:

• Voice agent systems are increasingly prevalent across diverse devices.
• Despite advancements, the usability of voice user interfaces (VUIs) remains a significant challenge.
• Existing VUI design guidelines often lack a conversational flow perspective.

Purpose of the Study:

• To develop practical, conversation-focused guidelines for voice interaction design.
• To address the need for more comprehensive guidance for VUI designers and developers.
• To improve the overall usability of conversational voice agent systems.

Main Methods:

• Developed 12 new voice interaction design guidelines based on user cognitive strategies.
• Evaluated the proposed guidelines with 60 experts in voice interaction.
• Gathered expert feedback on the usefulness and applicability of the guidelines.

Main Results:

• The 12 proposed guidelines were evaluated by experts.
• Participants provided valuable insights into the practical application of the guidelines.
• The study identified key areas for improving voice interaction design.

Conclusions:

• The developed guidelines offer practical support for designing better conversational voice agents.
• User cognitive strategies are crucial for effective voice interaction design.
• Further refinement and adoption of these guidelines can enhance VUI usability.
