摘要
本论文设计了一种基于语音通信的门禁系统,该系统利用AT24C存储器通过ASR算法进行密码的训练与存储,以MIC接收语音信号并通过单片机进行预处理和DTW算法频域分析,以频谱分布概率是否符合R-square>0.9的近似条件、损失矩阵累积距离是否符合算法预期,进行语音密码的检验。通过实际系统模型测试与分析,该系统可稳定工作,且对比效率较高,针对性强,成本较低,有较高的市场应用价值。
This paper designed a kind of entrance guard system based on voice communication,the system USES AT24C storage password by ASR algorithm of training and storage,with MIC receive speech signal preprocessing and DTW algorithm and through the single-chip microcomputer,frequency domain analysis to spectrum distribution probability whether accord with R-square>0.9 the approximate conditions,expected loss matrix is in line with the cumulative distance algorithm,speech password of inspection.Through actual system model test and analysis,the system can work stably,and has high contrast efficiency,pertinence,low cost and high market application value.
