Abstract [en]

In this work we extend the test utterance adaptation techniqueused in vocal tract length normalization to a larger number ofspeaker characteristic features. We perform partially joint estimation of four features: the VTLN warping factor, the corner position of the piece-wise linear warping function, spectral tilt in voiced segments, and model variance scaling. In experiments on the Swedish PF-Star children database, joint estimation of warping factor and variance scaling lowered the recognition error rate compared to warping factor alone.
