Description

This paper describes integration of speech recognition and semantic interpretation for spontaneous speech understanding. First, we propose a framework of semantic interpretation where a concept is a unit of semantic understanding and an utterance is regarded as a sequence of concepts with an intention. Secondly, we describe a basic search method which detects concepts from a phrase lattice by island-driven search evaluating linguistic likelihood of concept hypotheses. Moreover, an improved method to efficiently search for meaning hypotheses is proposed. This method quickly generates initial meaning hypotheses allowing deletion of concepts. Then, the initial meaning hypotheses are repaired by re-searching for missing concepts using prediction knowledge associated with the initial meaning hypotheses. Experimental results show that 92% of understanding rate has been acheived, and that the improved method has realized efficient search without reducing its performance.
