Par rapport au DSP HiFi 4, ce DSP de cinqui\u00e8me g\u00e9n\u00e9ration multiplie par 2 les performances de traitement audio et par 4 les performances de traitement dans les r\u00e9seaux de neurones ce qui en fait une solution id\u00e9ale pour les interfaces utilisateur \u00e0 commande vocale que l\u2019on trouve dans les assistants personnels num\u00e9riques et les syst\u00e8mes d\u2019infodivertissement automobiles.<\/p>\n
