摘要：将嵌入式系统和语音识别技术结合起来,设计并制作了一款基于语音识别的新型电子秘书手机。系统在硬件上以基于PXA270处理器的XScale平台为控制核心,经RS232串口外扩语音识别和GSM/GPRS模块。以Linux作为操作系统,通过对XScale平台和语音识别模块的编程,实现了录音、语音设定闹钟时间、自动播放以及自动群发短信等功能。测试结果说明:系统特有的图形化界面以及基于语音的人机交互方式可以方便地将重要信息准时通知给多人,实现了电子秘书的功能。
By combining embedded system with speech recognition technique, a new type of electronic secretary mobile phone based on speech recognition is designed. As its key controller, XScale board based on PXA270 is connected with modules of speech recognition and GSM/GPRS via RS232 serial ports. By making the program on XScale and speech recognition module in Linux operating system, the expected functions are realized including audio recording, audio clock setting, auto-playing and auto-sending messages. The test results show that the specific graphic user interface and phonic manipulation can conveniently send important messages to others on time, which exhibits the function of an electronic secretary.
