摘　　要：依托于云端的智能语音设备,虽然在运算速度、数据量、智能化程度等方面有很大的优势,但也极大地增加了被黑客攻击的风险。基于听觉的嵌入式人机交互便是该领域的一个热门研究课题。本设计采用STM32F103C8T6的32位微控制器、LD3320的语音识别芯片、MR628-TTS语音合成模块和OLED液晶显示屏对整体结构以及软硬件设计,最终实现由一级指令触发,二级指令持续控制的非接触式语音控制系统,通过语音关键词来达到对外部电器的非接触式语音控制。Intelligent voice devices based on the cloud have great advantages in terms of computing speed,data volume and intelligence,but they also greatly increase the risk of being attacked by hackers.Embedded Human-Computer Interaction based on hearing is a hot research topic in this field.In this design,the main core control module uses the STM32F103C8T632-bit microcontroller developed by STMicroelectronics,and the speech recognition module uses the LD3320 voice recognition chip developed by ICRoute,and the speech recognition part is controlled by the STC11L08XE microcontroller alone.Combined with the MR628-TTS speech synthesis module,OLED liquid crystal display and other peripherals,the overall structure of the voice control system and each control module are designed.Finally,the non-contact voice control system triggered by the first level instruction and continuously controlled by the second level instruction is realized.Users can achieve the non-contact voice control of external electrical appliances by speaking the specific voice key words set in the program.
