摘　　要：设计一种基于语音识别技术的便携式语音提示器,采用STC90LE52系列单片机作为核心处理器,采用ICRoute公司生产研发的LD3320语音识别芯片实现语音识别功能.该系统属于非特定人语音识别,识别关键词列表可以由用户自己进行动态编辑.并对该语音识别系统的总体结构、主控制模块和语音识别模块的软硬件设计进行详细阐述.实验结果表明:该系统识别准确率高,结构简单,性价比高,具有较高的推广应用价值.The design of a portable intelligent voice prompter based on STC90 LE52 microcontroller as the core processor is being proposed,and its speech recognition function is introduced by the single chip LD3320 from the ICRoute Corporation. In this paper,the design involving the software and hardware in-cludes the overall structure in voice control system and the main control module,and also the speech rec-ognition module is invented. The target of this system belongs to the speaker independent speech recogni-tion. What＇s more,the key words in the identifying list can also be edited dynamically by the customers. After a large amount of experiments validated,it has a simple structure and a fantastic recognition accura-cy rate as high as 99 %. Meanwhile,it can produce high quality at low cost,so it＇s convenient to popular-ize and apply.
