Speech is an ordered sequence of data. In speech processing, some processes, such as spectral frequency warping, speaking rate control, and mappings of speech to other sequences such as text, are represented by a warping transformation that preserves the order. In this report, we generalize warping using all-pass filters by analyzing it as a Lie group, and derive a general warping group, GW. Parametric representations of GW in time domain, frequency domain, and the tangent vector space are given and discussed systematically in terms of universality and implementation methods. |
