Abstract / Bemerkung
The combination of multiple speech recognizers based on different signal representations is increasingly attracting interest in the speech community. In previous work we presented a hybrid speech recognition system based on the combination of acoustic and articulatory information which achieved significant word error rate reductions under highly noisy conditions on a small-vocabulary numbers recognition task. In this study we extend this approach to large-vocabulary conversational speech recognition using the Gaussian mixture acoustic modeling paradigm. We demonstrate that the articulatory input representation we propose contains information which is complementary to that provided by standard MFCC features, and their combination can significantly reduce the word error rate on a large-vocabulary, conversational speech recognition task. Various combination strategies (feature-level, state-level and word-level combination) are compared and evaluated.
