Each type of sound has a by different range and with different frequencies: this study classified the voice type in Men using Fast Fourier Transform (FFT) method by recording each user's voice , then will be processed by FFT method to obtain the appropriate sound range. sound This study has obtained results with up to 80% accuracy. The results obtained from this study are quite consistent and there is evidence that the FFT method can be used in digital signal processing. Keywords: Fast Fourier Transform, Sound type, Men, Frequency]]>
