| Abstract: | Background The rapid advancement of generative AI and voice assistants has expanded their potential applications, moving beyond straightforward task implementation to more complex conversational interactions. Design considerations, such as humanization through voice and visualization, are critical in shaping user experiences and emotional perceptions. Purpose This study aims to explore how emotional values perceived from voice assistants can be balanced between humanization and robotization. It investigates user acceptance, preferences, and the psychological and emotional reasons underlying the need for humanized voice assistants. Method The study employed a qualitative approach, utilizing prototype testing, concept evaluation, and exploratory interviews. Participants interacted with voice assistant prototypes featuring varying degrees of humanization, including facial expressions and voice characteristics. Data were collected through open-ended questions to capture diverse perspectives on humanized versus robotic elements. Results Findings indicate that users generally prefer humanized features in voice assistants, attributing emotional resonance to human-like voices and appreciating avatars with dynamic animations. Humanized design elements, such as facial expressions and tone, enhance user satisfaction and emotional engagement. However, the balance between humanization and robotization must be carefully managed to avoid negative reactions. Conclusion The study highlights the importance of integrating emotional support features into voice assistants. While users are open to advanced features, both functional and design-wise, future research should further investigate the impacts of highly realistic avatar animations and the psychological benefits of humanization. These insights provide valuable guidance for designers and engineers in developing emotionally supportive voice assistants that enhance user experience. Keywords: Voice assistant, Humanization, Prototype test, User Experience, Emotional Perception. |
