1、 基于单片机的语音识别系统基于单片机的语音识别系统 基于单片机的语音识别系统 - I - 摘要摘要 近几年来,智能化和自动化技术在玩具制造领域中越来越被关 注。本文介绍一种智能化小车控制系统的设计语音控制小车。语 音控制小车是基于 SPCE061A 的代表性兴趣产品,它配合 61 板推出, 综合应用了 SPCE061A 的众多资源,小车采用语音识别技术,可通过语 音命令对其行驶状态进行控制 。首先介绍了 SPCE061A 的主要性能及 其引脚的功能;接着完成了电源电路、复位电路、键盘电路、音频输 入电路,音频输出电路和无线控制电路等硬件功能模块的设计。软件 设计模块能实现智能小车的前进、后退、
2、转向、停止、避障、表演动 作以及循线等功能。测试表明,在环境背景噪音不太大,控制者的发 音清晰的前提下,语音控制小车的语音识别系统能对特定的语音指令 做出智能反应,做出预想中的有限的动作 关键词关键词 :spec061a 语音识别 驱动电路 声控小车 智能反应 基于单片机的语音识别系统 - II - AbstractAbstract In recent years, Intelligent and automation technology in the toy manufacture have been paid more and more attention.Introduce an in
3、telligent vehicle control system design. SPCE061A program the system to single-chip, based on implementation of the cars voice control, This paper introduces the hardware sub-system design and implementation. The SPCE061As main characters and pin function are introduced firstly. Completed the power
4、circuit, reset circuit, keyboard circuitry, audio input circuits, audio output circuit and control circuit of wireless hardware such as the design of function modules. Software design module can achieve smart car forward, backward, turn, stop, obstacle avoidance, performing actions, as well as on-line functions. Test showed that the background noise in the environment is not too great, control persons under the premise of clear pronunciation, voice control car speech recognition systems f
