In this paper, we revisit the linear transformation for VTLN on conventional MFCC proposed by Sanand et al. in [1], using the idea of band-limited interpolation. The filter-bank is modified to include half-filters at zero and nyquist frequencies, as the full symmetric spectrum is required for performing bandlimited interpolation. In this paper, we show that… CONTINUE READING
