Description
We are studying a CFG-based speech parser that outputs scored subtree sequences. In order to deal with spontaneous speech, the syntactic rules are written to parse subtrees rather than sentences. Bigrams of preterminal symbols are used during beam search. We previously conducted pause unitbased experiments and have confirmed that our method yields good performance. In this paper, we report on two kinds of performance improvement; i.e., the dictionary access improvement and the improvement of beam search. We also discuss ways to deal with more than one pause unit.
