Short Paper Verifyer-Tupel for Audio-Forensic to determine speaker environment

In this paper a new concept for audio classification and analysis is presented to determine the authenticity of the speaker’s environment. The overall concept’s characteristic is determined though an introduced Verifyer-Tupel which enables a detailed analysis of every kind of media. The purpose, the practise as well as the need of this Verifyer-Tupel is anchored in forensics. As we are clarifying in this paper, the Verifyer-Tupel can have an essential impact on investigations in accumulating evidence to proof a crime. Within the Verifyer-Tupel four different stages are classified which include distinct syntax and semantic features of information. We demonstrate its application to the medium audio and list concrete features for each stage. Our background is the determination of a speaker’s certain equipped, overall environment. This can be for example a trainstation or an airport with low quality audio devices or a class room or laboratory with high quality equipment. The Verifyer-Tupel provides an indirect channel for a speaker verification. The proposed concept is scalable for other media such as text, image, video or 3d-complexes. As a result we will show the Verifyer-Tupel’s impact on a new classification of information, esp. audio feature extraction and in particular, the verification of the authenticity of information.
