摘要
采用LD3320非特定人声语音识别芯片以及STC11L08作为主控MCU设计智能声控小车。语音识别芯片和主控MCU之间采用SPI通信协议交换数据传递识别结果。主控MCU识别语音并形成小车控制指令,经由无线传输控制芯片发送至运动控制板上,通过控制电机达到控制小车运动的目的。测试表明,小车对语音指令识别的响应速度快、识别精度高。
In order to improve the precision of the intelligent voice car control,non-specific human speech recognition ship LD3320 is used as voice recognition module,and STC11L08 is used as main control MCU.The SPI communication protocol is adopted for exchanging data between speech recognition chip and MCU control.The main control MCU is responsible for processing the results of identification form car control instruction.And CC1101 is used to send commands to the control panel on the car movement wireless receiving chip.After receiving the car control command from the control panel,the motor is controlled by the motor drive circuit according to the command,so as to achieve the purpose of controlling the car movement by voice.The actual test shows that the car responds quickly to the voice command recognition,and the recognition accuracy is high.
