Abstract
(EN)
Systems, methods, and apparatuses for detecting voice distortion are disclosed. In some aspects, a communication device may decode a silence insertion descriptor (SID) frame to identify a pattern associated with the SID frame and correlate the pattern with a reference pattern for the SID frame. Based on the correlating, the communication device, in some examples, may determine whether the SID frame is de-synchronized. In one or more examples, determining whether the SID frame is de-synchronized may comprise determining that a consecutive N number of SID frames fail to match the reference pattern. Additionally or alternatively, the communication device may adjust at least one parameter to re-synchronize a voice signal associated with the SID frame upon determining that the SID frame is de-synchronized.

L’invention concerne des systèmes, des procédés et des appareils pour détecter une distorsion de voix. Selon certains aspects, un dispositif de communication peut décoder une trame de dispositif de description d’insertion de silence (SID) pour identifier un motif associé à la trame SID et mettre en corrélation le motif avec un motif de référence pour la trame SID. Sur la base de la mise en corrélation, le dispositif de communication, dans certains exemples, peut déterminer si la trame SID est ou non désynchronisée. Dans un ou plusieurs exemple(s), la détermination du point de savoir si la trame SID est ou non désynchronisée peut consister à déterminer qu’un nombre N consécutif de trames SID ne parviennent pas à mettre en correspondance le motif de référence. En outre ou en variante, le dispositif de communication peut ajuster au moins un paramètre pour resynchroniser un signal vocal associé à la trame SID lors de la détermination du fait que la trame SID est désynchronisée.
