Comparing the User Preferences Towards Emotional Voice Interaction Applied on Different Devices: An Empirical Study.

Voice interaction has been widely used. Designers hope to use artificial intelligence technology to create humanlike voice assistants, which not only help users handle the daily chores, but also provide emotional support and communication. Voice interaction has been utilized for both mobile and home automation, and many researchers have studied the emotional voice interaction of various devices. As different voice interaction products have diversified orientations and the functions integrated in them varies, users may prefer to use them under different operating conditions or interaction modes. This paper chooses mobile phone voice assistant and smart home voice assistant as study subjects, representing mobile and stand-alone voice assistant respectively. A 2 (voice assistant type: mobile phone assistant V.S. smart home assistant) × 3 (interaction level: low V.S. medium, V.S. high) between-subjects experiment was conducted. Then the influences of different devices and voice interaction modes on user emotional experience were discussed. Thus it provides reference and guidance for the voice interaction design of corresponding products.
