Abstract[English]
The invention relates to a method for temporal alignment between the characteristics of a first signal and the characteristics of a second signal, the first signal and the second signal being broken down temporally into a plurality of frames, the method comprising, for a current frame of the second signal: obtaining (208) a set of unweighted attention scores, wherein each score represents a probability of the current frame in question matching a frame of the first signal, and obtaining (309), by a trained filtering module, a set of weights, derived from a combination of unweighted attention scores obtained for a given temporal context comprising the current frame and at least one frame of the second signal temporally adjacent to the current frame, weighting (309) the attention scores with the weights obtained in order to produce a set of weighted attention scores; producing a linear combination (212) of the characteristics of the first signal with the weighted attention scores in order to obtain an estimate of the realigned characteristics.[French]
Il est proposé un procédé d'alignement temporel entre des caractéristiques d'un premier signal et des caractéristiques d'un deuxième signal, le premier signal et le deuxième signal étant décomposés temporellement en une pluralité de trames, le procédé comprenant, pour une trame courante du deuxième signal: une obtention (208) d'un ensemble de scores d'attention non pondérés, où chaque score représente une probabilité de correspondance entre la trame courante considérée et une trame du premier signal, et une obtention (309), par un module de filtrage entrainé, d'un ensemble de poids, dérivé d'une combinaison de scores d'attention non pondérés obtenus pour un contexte temporel donné comprenant la trame courante et au moins une trame du deuxième signal temporellement voisine de la trame courante, une pondération (309) des scores d'attention avec les poids obtenus pour produire un ensemble de scores d'attention pondérés; une combinaison linéaire (212) des caractéristiques du premier signal avec les scores d'attention pondérés pour obtenir une estimation des caractéristiques réalignées.
