摘要
基于语音识别芯片LD3320设计并制作了一款非特定语音控制小车,给出了小车的硬件设计方法和C51控制软件流程。小车以STC12单片机为微控制器,由串口接收LD3320的语音识别代码,由ULN2003控制步进电机的转速和转向。在残障人轮椅,智能玩具等领域有潜在的应用前景。
A non-specific voice car based on speech recognition chip LD3320 was designed and made. The hardware design method and controlling software flow based on C51 were presented. The car was based on the STC12 microcontroller, the voice recognition code was received from the serial port of LD3320. The speed and steering of stepper motor were controlled by the ULN2003 driver. It has potential applications in the fields of disabled wheelchairs and intelligent toys applications.
