The model of code is insufficient for a complete description of a verbal communication. The description of codification and decodification supposes the ideal state of communication, but its defeat has to be interpreted as the result of some jammings either on the canal’s level or on the level of disposition of information process. Eventual disfunctions of verbal communication are determined by contextual hypothesis that are not explicitly expressed but implicitly. In order to explain the inferential processes it is necessary to exceed the model of code and to introduce a new concept of communication according to the inferential model. Speech action has a double dimension: on the one hand, it can be explicit. It means that literal meaning of discourse doesn’t defraud the expectations of the speaker, on the other hand, it can be implicit. It means that every meaning that is not associated directly with the significant and that is calculated starting from the significants can be assumed in a customary way during the message.
