摘要随着电子、信息技术的飞速发展,语音识别被广泛的应用在各个领域。常见的应用领域有:语音输入系统,如于键盘输入方法;语音控制系统,如工业控制、语音拨号系统、智能家电、声控智能玩具等;智能对话查询系统,银行服务、股票查询服务等等。当然这些应用都要建立在对语音的准确识别的基础上。
本项目主要采用凌阳科技公司的一款SPCE061A单片机进行设计,主要利用它特有的语音识别功能来实现对小车行驶状态的控制。比如输入预先训练好的语音命令“前进”,小车根据命令向前行驶一段距离,输入“左转”,小车向左转弯。利用语音命令代替了传统的遥控手动控制。小车接收命令的同时,向外界发出语音信号,从而实现人车之间的简单的交互。
为减小声音信号衰减,以及外部声音信号的干扰对语音命令的干扰造成的误差,本设计采用无线高频信号发送的模式,来实现语音命令的传送,即设计中采用两个SPCE061A单片机控制系统,第一个专门负责语音信号的采集,然后发送语音命令的编码。另外一个根据接收的语音命令编码,来控制小车的行驶状态。采用固定码PT2262无线发射模块和PT2272接收模块。

The Designed of Voice Remote Control Car Based on SPCE061A

Abstract With the rapid development of information technology, speech recognition is widely used in various fields. Common applications: voice input system, such as the keyboard input method; voice control system, such as industrial control, voice dialing systems, smart toys; intelligent dialogue and inquiry system, for example banking services, stock query services. Of course, these applications should be built on the accuracy of speech recognition.
The design, based on SPCE061A which is made by Sunplus pany, uses SPCE061A’s unique voice recognition capabilities to achieve the control of the car. Such as pre-trained mand input "Forward". The car would move forward. The car turning left when mand is "left". Using mands instead of the traditional remote manual control. When received mand, the car will generate a voice signal. Thus people and the car could achieve simple interaction.
To reduce the voice signal attenuation and interference from external sound signal this design uses high-frequency signals sent by the wireless mode to the transmission of the system uses two chips of SPCE061A. The first one is d
