同步录音录像作为固定言词证据的一种方式,比笔录更为全面,可以反应犯罪嫌疑人、被告人陈述内容之外的讯问信息。同步录音录像对讯问过程的全面反映,可以起到监督讯问程序合法性的作用。为实现全面记录,同步录音录像应从提审开始,检察机关也有权派员参与同步录音录像,开展相关监督和指导。同步录制的音频、视频对于案件实体性事实和程序性事实都是证据,但根据证明对象不同,分属于不同证据种类。 As a way of fixed verbal evidence, synchronous audio-video recording is more comprehensive than transcript, which can reflect the interrogation information beyond the content of criminal suspects and defendants. Simultaneous recording and recording of the interview process can reflect the legitimacy of the interrogation procedure. In order to achieve a comprehensive record, simultaneous recording and recording should begin with the trial. Procuratorial organs also have the right to send staff members to participate in simultaneous recording and recording and carry out relevant supervision and guidance. Simultaneous recording of audio and video is evidence of the substantive and procedural facts of the case, but depending on the different objects of the evidence, they belong to different categories of evidence.
