Applying speaker adaption techniques to correlated features

摘要

Systems and methods for applying feature-space maximum likelihood linear regression (fMLLR) to correlated features are provided. A method for applying fMLLR to correlated features, comprises mapping the correlated features into an uncorrelated feature space, applying fMLLR in the uncorrelated feature space to obtain fMLLR transformed features, and mapping the fMLLR transformed features back to a correlated feature space.
