%X the use of smartphones is increasing among the people. Smartphones in which has many functions such as communication, entertainment, commerce and even banking are clearly very useful in everyday life. However, this is not balanced by public awareness of the possibility of crime that continues to grow as well. The crime of telephone fraud / scam calls by asking for an OTP (One Time Password) code very often takes its toll because the victim is only asked to provide a few digits of a code that they may think is meaningless. if the victim was negligent and provided their code, the losses suffered would be enormous.  This study aims to implement the Audio Forensic method as a means of proving fraudulent crimes through telephone conversations. The stages of voice recognition analysis that will be carried out including pitch, formant and bandwidth analysis, graphical distribution, and spectograms on phone voice recordings.  In this study, it was found that the stages of voice recognition analysis, namely pitch, formant and bandwidth analysis, graphical distribution, and spectograms can prove the authenticity of recorded phone calls and prove the perpetrators of fraud. Also each analysis that carried out has a different level of position to prove the authenticity of the sound recording where the formant and bandwidth analysis is at the top level and the pitch analysis is at the bottom level.
