To find the trouble of secret phrase the executives and improve the convenience of authentication systems, biometric authentication has been broadly considered and has pulled in unique consideration in both scholarly world and industry. Numerous biometric authentication systems have been explored and grown, particularly for cell phones. The Voice is a signal of limitless data. Digital processing of speech signal is vital for rapid and exact programmed voice recognition technology. These days it is being utilized for medical care, communication military and individuals with handicaps in this manner the digital signal cycles, for example, Feature Extraction and Feature Matching are the most recent issues for investigation of voice signal. To remove important data from the speech signal, settle on choices on the cycle, and get results, the information should be controlled and examined. Fundamental technique utilized for removing the features of the voice signal is to discover the Mel frequency cepstral coefficients. Mel-frequency cepstral coefficients (MFCCs) are the coefficients that aggregately address the transient force range of a sound, in view of a linear cosine transform of a log power range on a nonlinear Mel size of frequency
