Research On Usability Of Intelligent Speaker In Voice Interaction Design

With the innovation of Internet technology and speech recognition technology,intelligent voice interaction has become the latest way of human-computer interaction.Voice user interface,voice interaction process,voice technique and voice color have become the key elements of the interaction between intelligent speakers and users,which puts forward higher requirements for usability,to improve the user’s voice interaction experience becomes more and more important.Therefore,it is of great significance to establish a usability evaluation model suitable for intelligent speaker voice interaction by scientific means to standardize the usability evaluation method of intelligent speaker voice interaction,which is of great significance to improve the user experience of intelligent speaker.In order to obtain the usability evaluation elements of intelligent speaker voice interaction,firstly,the usability influencing factors are analyzed from the dimensions of intelligent speaker voice interaction task,interaction process and interaction interface;Then,combined with the analysis of user characteristics and user experience,the usability of user experience in different scenarios is summarized,and the key influencing factors of the usability of intelligent speaker voice interaction are obtained as accurate and comprehensive as possible;Finally,the key influencing factors are extracted as the usability evaluation index.According to the principle of usability evaluation,the dimensions of the extracted evaluation indexes are divided through expert discussion,and the dimensions of the usability evaluation of intelligent speaker voice interaction are obtained.The analytic hierarchy process(AHP)is used to allocate the weight of the evaluation index,and the final evaluation index system of voice interaction usability of intelligent speakers is selected.Based on the evaluation system,the usability index of four samples of voice interaction is quantified.According to the characteristics of intelligent speaker voice interaction,the usability evaluation model is constructed by using fuzzy analytic hierarchy process,and the usability evaluation results of four samples are determined.According to the evaluation results of voice interaction of Xiaomi intelligent speaker,the optimization design strategy of voice interaction of intelligent speaker is proposed,and targeted improvement is carried out.The usability test is used to compare and analyze the design before and after the improvement,which verifies the guiding significance of the model to the optimization design of voice interaction.The paper has 46 pictures,38 tables,and 89 references.
