Assessment of the Speech Material Usability for Forensic Speaker Identification by Voice and Sounding Speech

The article considers the relevant issues of forensic examination of sound recordings in terms of determining the speech material usability degree for speaker identification by voice and sounding speech. Factors affecting the degree of speech material usability are listed and analyzed. Special attention is paid to the comparability of the speech material on the original phonogram and on the sample phonogram. Methodological approaches to solving the issue of determining the degree of speech material usability are proposed. The rationale for drawing a conclusion based on the results of forensic speaker identification is provided.
