Abstract

In today's speech recognition systems, linear or nonlinear transformationsare usually applied to post-process speech features forminginput to HMM based acoustic models. In this work, we experimentwith three popular transforms: HLDA,MPE-HLDA and Region DependentLinear Transforms (RDLT), which are trained jointly withthe acoustic model to extract maximum of the discriminative informationfrom the raw features and to represent it in a form suitablefor the following GMM-HMM based acoustic model. We focus onmulti-lingual environments, where limited resources are availablefor training recognizers of many languages. Using data from GlobalPhonedatabase, we show that, under such restrictive conditions,the feature transformations can be advantageously shared across languagesand robustly trained using data from several languages.
