Today, the most common architecture for speech understanding consists of a combination of statistical recognition and robust semantic analysis. For many applications, however, grammar-based recognisers can offer concrete advantages. In this paper, we present a methodology and an Open Source platform (Regulus), which together permit rapid derivation of linguistically motivated recognisers, in ei...

Works dealing with grammatical inference of stochastic grammars often evaluate the relative entropy between the model and the true grammar by means of large test sets generated with the true distribution. In this paper, an iterative procedure to compute the relative entropy between two stochastic deterministic regular grammars is proposed. Resumé Les travails sur l’inférence de grammaires stoch...
