Leveraging speaker-dependent variation of adaptation

Arindam Mandal, Mari Ostendorf, Andreas Stolcke

This work introduces an automatic procedure for determining the size of regression class trees for individual speakers using an ensemble of speaker-level features to control the number of transformations, if any, that should be estimated by maximum likelihood linear regression. Experiments with a state-of-the-art speech recognition system that uses this procedure show improvements in word error rate for conversational telephone speech.
