语音识别智能小车
摘 要
本文介绍一款语音识别智能小车的设计。该小车以SPCE061A为控制核心，可通过语音识别对其行驶状态和控制模式进行控制和切换。本设计主要完成了各部分硬件模块的设计，同时实现了智能小车的语音识别、语音播放、模式切换、行驶状态控制、无线遥控等功能的软件设计，从而使小车和控制者具有一定的交互功能。测试表明，小车可以根据控制者的操作做出相应的动作。

ABSTRACT
This paper introduces speech recognition of intelligent car design. The car to SPCE061A as control core, what but through the speech recognition on the operation and control model control and switch. This design main completed each part of the design of the hardware modules, and realize the intelligence of the car speech recognition, speech broadcast, mode switch, driving state control, wireless remote control functions of software design, so as to make the car and the controllers have certain interactive function. Tests show that, according to the operation of the car can controller make corresponding action.
