1  背景 

随着人们生活水平的提高和安全意识的加强，锁具系统的安全性变得至关重要，于是出现了密码锁磁性锁、电子锁、激光锁、声控锁等等锁具，它们是在传统钥匙的基础上，利用一或多组密码，不同声音不同磁场，不同声波，不同光束光波，不同图像(如指纹、眼底视网膜等)等来控制锁的开启。本文采用语音识别技术和键盘控制输入相结合，在凌阳SPCE061A单片机上实现一种语音电子密码锁认证系统。

2  语音电子密码锁的系统功能

本系统主要由凌阳SPCE061A单片机、MIC输入电路、语音输出电路、4×4键盘、6位七段LED显示、输出控制及FLASH存储器组成。系统主要的功能是：在训练时，说话人的声音通过麦克风进入说话人语音信号采集前端电路，由语音信号处理电路对采集的语音信号进行特征化和语音处理，提取说话人的个性特征参数并进行存储，形成说话人特征参数数据库。在识别时，将待识别语音与说话人特征参数数据库进行匹配，完成语音识别以及键盘的控制，实现激活或解除锁具，最终完成开锁。系统是依靠硬件和软件地密切配合，由凌阳SPCE061A单片机的灵活控制实现的。语音输入由于受到外部环境的干扰，有可能出现错误，但通过多次的训练可以使语音对比和识别有很大的提高。

3  电子密码锁硬件的设计 

本系统采用具有内核的凌阳SPCE061A单片机，该芯片内有ADC、DAC、定时器／计数器、RAM、FLASH等器件，加上适当的外围电路与配套的凌阳公司的集成开发环境，可以很方便.......

1 Introduction

As people's living standards improve and strengthen the sense of security, safety locks system becomes essential, therefore a password lock, magnetic locks, electronic locks, laser lock, voice-activated lock locks, etc., they are On the basis of traditional keys, using one or more passwords, different voices, different magnetic field, different sound, different light beams of different images (such as fingerprints, retina retina, etc.) to control open the lock. In this paper, using speech recognition technology and keyboard to control the importation of the integration of SCM in Sunplus SPCE061A achieve a voice on the electronic certification system password lock.

2  voice electronic password-lock system 

This system is mainly composed of Sunplus SPCE061A SCM, MIC input circuit, voice output circuit, 4 × 4 keyboard, six Qiduan LED display and output control and FLASH memory components. System is the main function: the training, the speaker's voice through a microphone into the speaker voice signal acquisition front-end circuit, by voice signal processing circuit on the acquisition of the characteristics of voice signals and voice processing, from the speaker's personality characteristics and parameters Store, a speaker parameters database. In recognition, will be voice recognition and speaker parameters database matching, voice recognition and complete control of the keyboard, and activate or release of locks, the final completion of the lock. System is......
