The Design And Realization Of Automatic Flute Language Recognition System Based On ARM

Flute language recognition transfer the flute language to the text or the language which humans can understand,by simulating human's hearing. Combinated with the improving speech recognition technology and widely applied embedded technology and the unmanned technology, the utomatic flute language recognition technology on embedded,which has good timily and high cost-effective,lower power consumption, will become a supplementary information gathering means for unmanned technology.This paper introduce the design and implementation of the flute language recognition system,based on three aspects: algorithm analysis , hardware environment , and the implementation of the software and hardware. In theory, this paper based on the former short-time energy algorithm,has setted dynamic energy thresholds,meeting the request of timily; In hardware environment ,this paper combinating the request of flute language recognition, introduce the hardware used by this system. Including arm s3c2410 microprocessor as module, Uda1341ts with chips of digital audio as a module, and using the iis data bus capable in S3c2410 microprocessors to achieve the communication between microprocessor and digital speech module. In the implementation of the software and hardware,this paper maily including as the flows: data collecting from digit speech module, the design of S3C2410 control module, the implementation of flute language recognition module, and the comucation between ARM and computer.The research for automatically flute language recognition maily based on ARM,and then is implementated on ARM9.The result shows that,this system can accurately and automatically recognises different kinds of flute language, and can meet the request of timely system.
