       abstract = {We apply multilayer perceptron (MLP) based hierarchical Tandem
features to large vocabulary continuous speech recognition in Mandarin.
Hierarchical Tandem features are estimated using a cascade
of two MLP classifiers which are trained independently. The first
classifier is trained on perceptual linear predictive coefficients with
a 90 ms temporal context. The second classifier is trained using the
phonetic class conditional probabilities estimated by the first MLP,
but with a relatively longer temporal context of about 150 ms. Experiments
on the Mandarin DARPA GALE eval06 dataset show significant
reduction (about 7.6\% relative) in character error rates by using
hierarchical Tandem features over conventional Tandem features.},
