通过调整语音助手音调，可提升用户对其吸引力与信任感。
Building Trust Through Voice: How Vocal Tone Impacts User Perception of Attractiveness of Voice Assistants
- 设计正向或中性音调的语音助手，增强用户好感。
- 用户对更吸引人的语音助手，信任度显著提高。
- 适合关注人机交互体验与语音设计的研究者。
语音助手（VAs）在完成简单任务时广受欢迎，但在复杂活动（如在线购物）中，用户常持保留态度。本研究探讨了语音特征（如音调）是否能提升语音助手在复杂任务中的吸引力与可信度。实验表明，语音助手的音调显著影响其被感知的吸引力与信任度。参与者更倾向于被正向或中性音调的语音助手吸引，并更信任他们认为有吸引力的助手。结论指出，通过精心设计语音，结合多样化的音调，可有效提升语音助手的感知可信度。
原文摘要 · Abstract (English)
Voice Assistants (VAs) are popular for simple tasks, but users are often hesitant to use them for complex activities like online shopping. We explored whether the vocal characteristics like the VA's vocal tone, can make VAs perceived as more attractive and trustworthy to users for complex tasks. Our findings show that the tone of the VA voice significantly impacts its perceived attractiveness and trustworthiness. Participants in our experiment were more likely to be attracted to VAs with positive or neutral tones and ultimately trusted the VAs they found more attractive. We conclude that VA's perceived trustworthiness can be enhanced through thoughtful voice design, incorporating a variety of vocal tones.
