CEPSTRAL METHOD OF SPEECH RECOGNITION

Анотація

 A cepstrum is the result of taking the Inverse Fourier transform (FT) of the logarithm of the spectrum of a signal. There is a complex cepstrum, a real cepstrum, a power cepstrum, and phase cepstrum. The power cepstrum in particular finds applications in the analysis of human speech. speech is one of the most important tools for communication between human and his environment. Therefore manufacturing of Automatic System Recognition (ASR) is desire for him all the time. In a speech recognition system, many parameters affect the accuracy of the Recognition System.
