With the popularity of intelligent products, more and more consumers can have personalized and diversified product experiences. Focusing on the anthropomorphism of intelligent products, this paper discusses the influences of different modes of intelligent voice communication on consumers' brand attachment. Based on the communication modes obtained from qualitative interviews, two experiments are designed and show that partner communication mode can stimulate consumers' brand attachment more significantly than servant communication mode can, and the para-social interaction between consumers and intelligent products explains its internal mechanism. In addition, brand personality plays a moderating role. According to the above conclusions, the research provides relevant management suggestions.
