【摘要】 人机交互是脑瘫康复训练机器人辅助系统的关键技术。语言训练对脑瘫患者康复起到至关重要的作用。针对有语言障碍的脑瘫患者,设计了语音语言康复训练系统。该语音语义测试系统底层控制器采用51单片机芯片,通过两个按键切换单字和词语短句模式;语音辨识采用LD3 320模块,下位机控制系统采用C语言,上位机用到C#进行编程。语音芯片把信号辨识结果通过串口发送到上位机,上位机根据语音语义规则进行辨识匹配,对测试完成评判和统计。该工作为脑瘫康患者的语音语义康复训练提供了关键技术。更多还原

【Abstract】 Human-computer interaction is a key technology of the robot aided system for the rehabilitation training of cerebral palsy. Language training plays a vital role in the recovery of cerebral palsy. A speech language rehabilitation training system is designed for patients with cerebral palsy with language disorders. The controller of the phonetic and semantic test system uses 51 single chip, through two key for words and phrases words switching mode; speech recognition uses LD3320 module, low level control system uses the C language, and high level control system adopts C# programming. The speech chip sends the signal of recognition results to the host computer through the serial port. The host computer performs recognition and matching according to the voice and semantic rules, and completes the judgments and statistics for the test. This work provides a key technique for the speech semantic rehabilitation training of the patients with cerebral palsy.更多还原
