摘　　要：为研制一种车载智能语音识别报警系统,采用多路拾音器实时采集车载语音,对语音数据预处理并特征提取后,基于人工智能(AI)技术和声学模型进行报警敏感词匹配,并将敏感词无线传输至连通公安报警系统的云平台。60名不同方言区的实验对象选用5个敏感词分别进行报警实验,结果表明:研制的系统智能语音识别准确率不小于96.7%,且与实验对象真实的报警意图无显著性差异(P>0.05)。In order to research and fabricate a vehicle intelligent voice recognition and alarm system, multichannel pickups are used to collect voice in vehicle in real time.After voice data preprocessing and its features extracting, the sensitive words are matched based on AI and acoustic model, and transmitted to the cloud platform connected with the public security alarm system.The alarm experiments with 5 sensitive words are conducted in 60 objects from different dialect area.The results show the accuracy of intelligent speech recognition is not less than 96.7 %,and there is no significant difference between the system and the real alarm intention of the objects, P>0.05.
