摘　　要：本文提出了一种基于嵌入式设备的非特定人声车辆运动声控终端的设计方案,采用嵌入式处理器构建了人声识别控制单元,实现了以非特定人声来控制试验小车的运行;提出了一种基于预处理、训练、特征提取及模式识别的非特定人声语音识别方案,将前期训练结果建立语音库,采用基于ANN的对比来实现控制指令识别。试验结果表明,本文所提出的方案针对不同性别、不同指令的非特定人声识别正确率能达到约90%,验证了本文所提出设计方案的有效性。In the paper,a design scheme of a non-specific vocal vehicle motion sound control terminal based on an embedded device is proposed.An embedded processor is used to construct a vocal recognition control unit,which realizes the control of the test cart operation with non-specific vocals.A non-specific vocal speech recognition scheme based on preprocessing,training,feature extraction and pattern recognition is established.The previous training results are used to build a speech database.ANN-based comparison is used to realize control instruction recognition.The test results show that the proposed scheme can achieve about 90%correct rate for non-specific human voice recognition with different genders and different instructions,which verifies the effectiveness of the proposed scheme.
