Disclosed is a method of adapting a neural network of an automatic speech recognition device, the method comprising the steps of: providing a neural network comprising an input stage, an intermediate stage and an output stage, said output stage outputting phoneme probabilities; providing a linear stage in said neural network; and training said linear stage by means of an adaptation set; wherein the step of providing said linear stage comprises the step of providing said linear stage after said intermediate stage.

L'invention porte sur un procédé d'adaptation du réseau neural d'un dispositif automatique de reconnaissance vocale comportant les étapes suivantes: création d'un réseau neural comprenant un étage d'entrée, un étage intermédiaire, et un étage de sortie émettant des probabilités de phonèmes; création d'un étage linéaire dans le réseau neural; et apprentissage de l'étage linéaire au moyen d'un jeu d'adaptation, l'étape de création de l'étage linéaire s'effectuant après celle de l'étage intermédiaire.
