Syntactic--Semantic interpretation of sentences in the MYRTILLE II speech understanding system

MYRTILLE II is a system which is now being implemented at CRIN in order to understand a wide subset of natural spoken French. In this paper we will concentrate on the syntactic-semantic component of the system. The general principle and overall architecture of MYRTILLE II are first briefly described. The way in which syntax and semantics are integrated in a unified representation is then presented. This representation is equivalent to a network with procedural nodes. Several examples of processed sentences are finally discussed. The system yields a tree structure of an input sentence. The examples presented show how syntax and semantics are used for solving typical problems which occur in speech understanding.
