MFCC (Mel-Frequency Cepstral Coefficients)
Mel-Frequency Cepstral Coefficients (MFCCs) ni uwakilishi thabiti wa sifa za sauti unaoiga mtazamo wa usikivu wa binadamu. Zilianzishwa na Davis na Mermelstein mnamo 1980, MFCCs ndiyo njia halisi ya uchimbaji wa sifa kwa utambuzi wa usemi na uchambuzi wa sauti za mazingira. Zinabananisha taarifa za masafa ya mawimbi ya sauti kuwa seti ndogo ya vigawo vinavyonasa maudhui ya kifonetiki huku zikiondoa maelezo yasiyo muhimu.
