录音剪辑检验的实验研究

目的寻找录音剪辑的检验方法。方法进行模拟仿真实验。分别用标准盒式录音机、微型录音机和MP3录制样本，再用物理剪辑、录音机具编辑、软件编辑等3种方法对样本进行剪辑，最后用VS3．0语音工作站进行检验。结果找到剪辑点痕迹特征在时域波形图、宽带语谱图、窄带语谱图上的反映。结论利用“语意连贯性检验”、“背景噪声图谱连贯性检验”、“突变声痕检验”等方法可以实现对录音剪辑的检验。

The study of recording editing examination by experiment

ObjectTo establish the methods of examining recording editing.MethodRecord the sample by normal recorder,micro-recorder and MP3;Then,edit the sample by three methods,which are physical edit,recorder edit and software edit;Finally,apply VS3.0 voice workstation to examine the edited records.Resultcharacteristics of wave diagram,voice broad band spectrum,as well as the voice narrow band spectrum at the edit points were found.ConclusionRecording editing can be examined by the methods of "identification of meaning consistency","identification of background noise consistency" and "identification of voice chop".
