Tartalmi leírás:
Forensics, as a multidisciplinary activity, has as its main task the provision of material evidence of all kinds. The scope of forensics includes all preliminary activities that are a necessary precondition for providing evidence, as well as work on clarifying criminal acts, especially those with unknown perpetrators, as well as actions performed immediately after cognition about the existence of the criminal act and which are part of police action. One of the main goals of forensics is the identification of persons. In recent years, there has been a growing interest and need to identify the perpetrator of a crime based on voice. A person's voice is a feature of identity, because just as there are no two identical fingerprints, two same handwriting or two same retinas, there are no two identical voices. Evidence based on voice analysis can be crucial for identifying, prosecuting and convicting the perpetrator. The information that is transmitted through speech communication is discrete in nature, because it consists of a series of elements from the set with a finite number of elements. The speed of the exchange of information, when it comes to speech, is determined by the physical limitations to which the human speech apparatus is subject. Forensic analysis of speech signal consists of three analyzes: auditory linguistic analysis, phonetic acoustic analysis and acoustic instrumental analysis. Forensic analysis of the speech signal uses the achievements of several different sciences through the application of various complex methods. The multidisciplinarity and complexity of the analysis makes this method of face identification extremely selective, and thus powerful.
