研究了使用人机交互的方式对脑瘫患儿进行康复训练的技术,设计了基于语音交互的脑瘫康复训练系统。该系统采用51单片机驱动整个系统,芯片采用LD3320语音芯片,下位机程序采用C语言编程,上位机采用Lab VIEW编程,通过串口传送的方式,把下位机接收到的命令传送到上位机,患儿通过识别上位机界面的图片,对应说出所要识别的文字,语音芯片进行识别,评价系统自动评判出患儿说的正确与否,并记录患儿每次识别所用的时间。案例实验验证了本设计的有效性。
The technology of rehabilitation training for children with cerebral palsy by means of human-computer interaction was studied, and a cerebral palsy rehabilitation training system based on voice interaction was designed. The system uses 51 single chip microcomputer to drive the entire system. The chip uses LD3320 voice chip. The lower computer program uses C language programming. The upper computer uses Lab VIEW programming and transmits the commands received by the lower computer to the upper computer. By identifying the picture of the PC interface, corresponding words and voice chips to be identified are identified, and the evaluation system automatically judges whether the children are correct or not, and records the time taken for each identification of the child. Case studies demonstrate the effectiveness of this design.
