With the rapid development of artificial intelligence technology in recent years,,especially the development of speech recognition,natural language processing and speech text,intelligent voice has been widely used in a variety of products,such as smart home,mobile Internet,automotive electronic terminal,intelligent robot,education,medical treatment,intelligent customer service and so on.Voice user interface is being reshaped into a new paradigm of human-computer interaction.Compared with the traditional graphical user interface,voice user interface is closer to the expression of natural language and can liberate users' hands and eyes.However,because of users' differences in speech cognition and behavior,the user experience of voice interaction can't meet the expectations of users in practice.It affects the operational feelings of users and reduces the willingness of users to use voice interaction.In this paper,taking the intelligent speaker voice interaction as an example,combined with the user mental model theory,this paper explores the factors that affect the user experience in voice interaction.First of all,based on the characteristics of voice interaction and the theory of user mental model in human-computer interaction,this paper decomposes the user mental model of voice interaction and divides it into three layers: cognitive layer,behavior layer and emotional layer.Secondly,through semi-structured interviews and means-target chain analysis to obtain and summarize the relevant elements of the three levels of the user mental model,according to its relevance to construct the user mental model.Through this model,we can explore the important factors that affect the user experience in voice interaction and their interaction.This helps designers understand the extent of the problem and impact of the user experience,and provides guidance to designers in the phase of voice interaction design and optimization.Finally,according to the data relationship of user mental model,this paper constructs the evaluation system of intelligent speaker voice interaction user experience,and carries on the experiment through the questionnaire,and provides suggestions from two aspects: voice interaction design optimization and voice interaction design for different proficiency users.Through the construction,analysis and design of the mental model of voice interactive users,this paper explores the internal relationship between the elements of user mental model and user experience design.By applying the user mental model to design evaluation,this paper helps designers to evaluate the user experience of voice interaction more comprehensively so as to guide the design practice.At the same time,it also provides research ideas and methods for the research of voice interaction user experience.
