摘要
由于语音控制的智能玩具车的成功响应情况受到距离的影响,为此设计了智能玩具车语音控制系统。该系统分为遥控部分和小车部分,通过将语音识别模块分配到遥控部分的方法,实现遥控部分近距离识别语音并发送指令,小车部分远距离接收指令并实现自主避障等功能。提出的系统采用STM32F103C8T6单片机为核心模块,辅助整合LD3320语音识别模块进行语音识别,利用HC-05蓝牙模块进行指令的传输和接收,通过语音控制实现小车的方向变化、加减速等。系统整体运行稳定,语音识别成功率高,操作简单直接,具有良好的前景。
Because the successful response of voice controlled intelligent toy car is affected by distance,the voice control system of intelligent toy car is designed. The system is divided into remote control part and car part. By assigning the voice recognition module to the remote-control part,the remote-control part can recognize voice and send instructions in a short distance,and the car part can receive instructions in a long distance and avoid obstacles independently. The system uses STM32F103C8T6 as the core module,integrates the LD3320 speech recognition module for voice recognition,HC-05 Bluetooth module for instructions transmission and reception,and realizes the functions of the car’s direction change,acceleration and deceleration through voice control,the system has the advantages of stable operation,high success rate of voice recognition,simple and direct operation,and good prospects.
