Design And Implementation Of Car Voice System Based On Intelligent Interaction

In recent years,with the rapid development of artificial intelligence,the intelligent interaction mode based on speech recognition technology is getting mature.Nowadays,the battle in the car voice interaction market is getting into incandescence.Voice technology providers with international reputation,such as Amazon,Google,IFLYTEK,AI Speech and so on,choose to cooperate with major car companies to promote the comprehensive upgrade of the conversational mode and natural mode of voice car system,which is based on intelligent interactive.Due to the particularity of drivers,the thesis designed to replace the traditional touch screen behavior with voice interaction to realize the query function of weather information,stock information,encyclopedia information,translation information,ancient poetry information,time and festivals information of voice query module,realize the playback function and search function of music,program of the entertainment module,realize the positioning function,the destination navigation and the map control function of the navigation module,realize the air conditioner controlling function,the window controlling function,the sunroof controlling function of the voice controlling car module,so as to ensure the safety and improve the interactive experience of drivers while driving.In order to store the data information of the car voice system,the thesis implements the design of the My SQL database and allows access to the data within each module of the system.In response to requirements of users,the thesis designs a listener,and based on the feedback received,the thesis controls the user interface to perform the corresponding update operation.For all the user interfaces of the system,the thesis sets up their own life cycle,and designs in the form of XML files to realize the layout of each widget.Based on the intelligent interaction mode,the thesis analyzes the development status at home and abroad as well as the existing problems of the car voice system,and expounds the speech recognition technology and speech synthesis technology used by the system.In the phase of requirement analysis,the thesis designs use case diagrams to realize the requirements analysis of the functions of the car voice system.Meanwhile,the thesis designs the system architecture diagram and functional structure diagram,so as to realize the overall design of the car voice system,and analyze the semantic composition and database structure in detail,so as to realize the summary design of the car voice system.During the phase of detailed design and implementation,the thesis adopts class diagrams and flow charts to explain the function realization of each module of the car voice system.For the car voice system that has been implemented,the thesis designs a test plan,and analyzes the test results,so as to verify whether the system meets the design expectations.For the high-speed driving environment of the car,the car voice system can solve the interactive pain points of drivers.By meeting the key needs for “entertainment travel” of drivers,the thesis designs a full voice interaction method based on the intelligent interaction mode to ensure the safety of drivers on the way,so as to realize the promotion of the value of voice interaction.At present,the car voice system has been released and reached the design expectations,which can meet the needs of market,so as to serve both the drivers and the enterprise.
