Use of spectral centre of gravity for generating speaker invariant features for automatic speech recognition

Abstract

In this paper, we present an approach to generate speaker invariant features for automatic speech recognition (ASR) using the idea of spectral centre of gravity(CG). This is based on the observation that if two signals are delayed versions of one another, then their CG’s also differ by the same amount. We exploit this idea to appropriately shift the mel… (More)
