Voice classification is one of the deeper research of speech recognition. Classification analysis of gender based sound with wav format using Praat software is a clever system that distinguish male and female voice through the system.

Subject for speech beginner musical scale pronunciation taken from college student of Sepuluh Nopember Institute of Technology aged 18 to 23 years old. From this study, the results from 100-150 Hz for men as well as 200-250 Hz for women.
