Dear all HTS users, I’m analyzing the SPTK especially the mcep. But I have something confusing..!! In _mcep.c, therer are two frequency
warping function freqt and frqtr. I think both functions are used for
frequency warping. But I can’t find any relationship with the paper what I’ve
ever seen. I saw the paper “An adaptive algorithm for
mel-ceptral analysis of speech” written in 1992. I can’t find any relationship with the
paper. What equation refer to the freqt and what equation represent the frqtr
in the paper? Or did I see the wrong paper? (It was referenced
in SPTKfre-3.2.pdf file) Best Regards, Youn-Sung Park |
