Research Of In-vehicle Entertainment System Base On The Speech Control

Recent years, consumers improve the requirements for the vehicle performance asincreasing number of automobile production and sales. Intelligence technology is one of thedemands of consumers are most concerned about, speech recognition technology (as a keytechnology) has become the focus of attention, and applied to the car, to replace thetraditional variety of operating keys.Objective of this paper is to develop a speech control entertainment system, which helpusers to drive safely during the free call, radio play, music video player and air conditioningcontrol. In the part of introduction, it describes the history of the development of speechrecognition technology and processes, comparing the research and application of theautomotive industry at china and abroad. In terms of the mathematical model, the existingmodels on the basis of previous theories, some bold attempt to improve the recognition rateof Chinese speech. Built with CSR’s ARM-A9core of CSRS3681host controller hardwaresystem, greatly enhance the computing speed and voice systems to enhance operationalefficiency. While using a special voice collecting and noise suppression circuit, suppressingambient noise and to achieve efficient and effective enhancement of speech signals,particularly those having excellent performance results in the vehicle noise environments.Using complex and powerful system software architecture, it enhances the speed andefficiency, and uses a comprehensive speech synthesis technology to increase the users’satisfaction’s rate.We design more practical experimental program for the effect of speech recognitionsystem. After careful testing and evaluation, the system achieved a better recognition rateand achieved the desired goals.
