What is FFT in MFCC?

FFT Used for frequency analysis, thus simplifying voice processing as it corresponds to human hearing. FFT Is an algorithm that implements discrete fouries transform (DFT). DFT is the transformation of each frame with N sample From time domain to frequency domain.

How is MFCC obtained?

MFCCs are obtained by taking Discrete Cosine Transform (DCT) of the spectral envelope.
