Streszczenie
Person recognition by voice system of the Lithuanian Institute of Forensic Examination is designed. Main application of this system is criminalistic person identification by voice. Identification futures are presented by means of statistical distribution diagrams of specific parameters and correlation coefficients between these diagrams. Thus an expert can motivate his decision by the help of diagrams and specific numbers. This enables, to compare with traditional sonographic approach, better motivate phonoscopic examination, accelerate the investigation and reduce requirements for investigative and comparative speech records. The investigation becomes independent from the speech text recorded in the investigative and comparative speech records.
