音频资料证据的有效提取研究

为了依法有效提取音频资料证据,保护人民群众合法权益和财产安全,在法律和技术层面研究音频资料作为证据的有效提取方法。首先在实战部门进行调研,并完成模拟场景实验分析,然后设计了包含真实环境、实战装备、人物场景模拟等复杂场景实验条件,接着进行了多场景基于音频资料的语谱图实验分析总结,最终获得有效的音频提取方法,并形成一套应用较强的提取规范。研究总结的方法和规范可运用到公安实战工作中,符合执法规范,可操作性强,获取的音频资料证据有效,实战价值高。

This paper studies the effective extraction method of audio data as evidence.The purpose of the research is to extract audio data evidence effectively and protect people's legitimate rights and property safety.First of all,the investigation is carried out and the simulation scene experiment is analyzed.Then,the complex experimental scene conditions are designed.And it contains the real environment,combat equipment,character scene simulation and other content.Second,the paper analyzes and summarizes the multi-scene speech spectrogram based on audio data.Finally,this paper obtains an effective audio extraction method,and forms a set of extraction specifications with strong application.The methods can be applied to the actual work of the public security,which are in line with the law enforcement norms,with strong operability and high practical value.
