CA 2663385

In one configuration, erasure of a significant frame of a sustained voiced segment is detected. An adaptive codebook gain value for the erased frame is calculated based on the preceding frame. If the calculated value is less than (alternatively, not greater than) a threshold value, a higher adaptive codebook gain value is used for the erased frame. The higher value may be derived from the calculated value or selected from among one or more predefined values.

Dans une configuration, l'invention consiste : à détecter l'effacement d'une trame importante d'un segment vocal accentué; à calculer, sur la base de la trame précédente, une valeur de gain de liste de codage adaptative pour la trame effacée; à utiliser, pour la trame effacée, une valeur de gain de liste de codage adaptative supérieure si la valeur calculée est inférieure (ou, dans une autre variante, non supérieure) à une valeur seuil, ladite valeur supérieure pouvant être dérivée de la valeur calculée ou sélectionnée parmi une ou plusieurs valeurs définies.
