The log-energy at the output of the filter bank may be expressed as: 1 2 0 ( ) ln( ( ) ), 0 N DFT k s m X k n M − = = ≤ <∑ (8) The discrete cosine transform (DCT) is operated to achieve the ��� cepstral coefficients �� as: 1 0 ( 0.5) ( )cos( ), 1, 2, , M r m r m c s m r R M − = − = =∑ … π (9) where ���� is the logarithm of the Mel spectrum, and R is the total number of cepstral coefficients.	cache/aiti-5597.pdf	txt/aiti-5597.txt
