Abstract
Island-driven parsers have interesting potential applications in Automatic Speech Understanding (ASU). Most of the recently developed ASU systems are based on an Acoustic Processor (AP) and a Language Processor (LP). AP computes the a priori probability of the acoustic data given a linguistic interpretation. LP computes the probability of the linguistic interpretation. This paper describes an effort to adapt island-driven parsers to handle stochastic context-free grammars. These grammars could then be used as Language Models (LM) by LP to compute the probability of a linguistic interpretation.File in questo prodotto:
