[Objective] The rapid development of intelligent acoustic systems has remarkably promoted the progress of human life. While the convenient communication is being build between human and machine, it has also exposed various security issues, which can greatly threaten users’ privacy, property security, and even personal safety. This paper makes a comprehensive introduction to the research status of intelligent acoustic system security and provides references for the related research work in China. [Coverage] The references are selected from domestic and international journals or conferences in the field of artificial intelligence system security, with a total of more than 50 articles. [Methods] We firstly establish the security model of the intelligent acoustic system and analyze the purposes and abilities of attackers. Then, we systematically summarize the existing acoustic system security studies into five topics, which are input components, pre-processing components, machine learning models, output components and actual implementation frameworks. Finally, we discuss future research trends. Particularly, we point out potential research directions of pre-processing and output components, which may need more attention. [Results] The researches about intelligent acoustic system security have achieved considerable results, but is still at the initial stage in all, which means there are more directions to be explored, and problems to be solved. [Limitations] Acoustic system security has developed rapidly in recent years. This article is limited by the timeliness of access to data, some included researches may have new progress. [Conclusions] The researches on speech system security have high practical value. However, the existing researches have limitations in research focus points and practicality. There are still a lot of blank areas awaiting for scholars to further explore and study.
