A design and implementation of speaker independent speech recognition system using ARM processor as the con-trol core is introduced. The system using the speaker independent speech recognition chip LD3320 of IC Route and 32-bit high-performance single-chip computer STM32F103C8T6 of ARM Cortex M3 kernel ST company as the main function body. SD card file system is realized in the system,the content in the SD card can be changed without changing the source code of microcon-troller to identify and dynamicly edit the keywords of list. A lot of practice proved that the design is suitable for the application of changing the identification content flexibly and return parameters in embedded component development. The design has higher cost performance, simple interaction,high recognition rate and strong expansibility,and is convenient for embedded application.
