| Abstract(in English) | This paper proposes a large vocabulary spontaneous dialogue speech recognizer using cross-word context constrained word graphs. In this method, two approximation methods "cross-word context approximation" and "lenient language score smearing" are introduced to reduce the computational cost for word graph generation. The experimental results using a "travel planning corpus" show that this recognition method achieves a word hypotheses reduction of 25-40% and cpu-time reduction of 30-60% compared to no approximation, and that the use of class bigram scores as the expected language score for each lexicon tree node decreases the 25-30% of word error rate compared to no approximation. |
