| Abstract(in English) | We present a novel method of integrating the likelihoods of multiple feature streams, representing different acoustic aspects, for robust speech recognition. The proposed integration algorithm dynamically calculates a frame-wise stream weight based on an entropy reduction caused by observing an input feature. Japanese broadcast news recognition experiments, integrating feature streams representing energy, amplitude drifts, and resonant frequency drifts, showed that the proposed method reduced error words by 9.2% in field reports and 4.7% in spontaneous commentaries relative to the best result obtained from a single stream. |
