Abstract

 Audio forensics is one of the sciences that mnyandingkan between science and scientific methods in the process of sound recording analysis to assist and support the disclosure of a crime required in the trial process. This article is intended to Analyze Voice Resemblance Towards Mobile Phone’s Voice Recorder: An Implementation of The Forensic Method Using Voice Recognition Technique, by using Forensic audio method  In Audio forensics: Theory and Analysis, namely Pitch Statistical Analysis, Forman and Bandwidth Statistical  Analysis, Graphical Distribution Analysis and Spectogram Analysis. However, in this study, researchers only  focus on identifying pitch and formants in the data to be analyzed. The results of the data analysis it can be  stated that the accuracy of the pitch analysis (F0) through Praat is very low and cannot be used as an indicator  to distinguish that a data is correct as the original voice, as evidenced by the results of the F0 value of the  original voice data and a very flexible and inconsistent comparison, some are the same, close to and even far from the F0 value of the subject data. This shows that everyone has a different pitch value because the intonation of each person's word pronunciation is different. It is possible that there are pitch values from several subjects that are almost the same.
