Abstract
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.

语音助手（VAs）因简单任务而流行，但用户通常不愿意在复杂任务中使用它们，比如网上购物。我们研究了是否VAs的语音特征（如语音语调）会使其被用户视为更有吸引力和可信度。我们的研究结果表明，VA的语音语调对其被用户视为更有吸引力和可信度具有重要影响。实验参与者更有可能喜欢带有积极或中性语调的VA，最终他们信任他们找到的更吸引人的VA。我们得出结论，通过深思熟虑的语音设计可以增强VA的可靠性。
