In this paper we present a simple speech recognition application in which an explicit knowledge base system is coupled to a connectionist machine. A set of Prolog rules describes the structural aspects of the words in the vocabulary, in terms of acoustico-phonetic events. These events are jointly evaluated by a multi-layer network in order to identify the corresponding word. The system provides good results, notably with unknown speakers.
