摘　　要：目前国内肢体残疾者数量逐年攀升,人口老龄化趋势明显,为了提高他们的生活质量,本系统采用用户的语音信号作为控制信息源,设计了一套基于语音识别技术的无障碍居家环境系统,包括中央控制平台、语音识别模块、执行终端节点等部分。通过将声音识别控制技术、无线信息传输技术、嵌入式移动计算技术相结合,将居家环境中的灯具、电子锁、报警器、电视机等电器设备通过无线网络节点互联为一个系统。经过系统测试在居家环境中语音控制的成功率在84%以上。The number of people with physical disabilities is increasing year by year, and the trend of population aging is more and more serious. In order to improve the quality of the life, a control system of accessible home environment [or the patients with serious disabilities was developed to control the home electrical devices with the voice of the pa- tients. The control system includes a central control platform, a speech recognition module, a terminal operation module, etc. The system combines the speech recognition control technology and wireless information transmission technology with the embedded mobile computing technology, and interconnects the lamp, eleetronie locks, alarms, TV and other electrical devices in the home environment as a whole system through a wireless network node. The ex- perimental results showed that speech recognition success rate was more than 84 % in the home environment.
