摘　　要：介绍了一种采用ARM处理器作为控制核心的非特定人语音识别系统的设计与实现,系统利用IC Route公司的非特定语音识别芯片LD3320与ARM Cortex M3内核ST公司的32位高性能单片机STM32F103C8T6组成功能主体,在系统中实现SD卡文件系统,在不更改单片机源程序的前提下,可更改SD卡中内容,达到识别列表关键词动态编辑,经过大量实践证明该设计适合嵌入式组件开发中需要灵活更改识别内容和返回参数的应用,设计具有高性价比、交互简易、识别率高、扩展性强等特点,便于嵌入式应用。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.
