Abstract

L'invention concerne un dispositif de traitement d'informations qui effectue une commande de volume dans laquelle un changement de volume ne se produit pas pendant la sortie d'une voix de guidage vocal ou similaire, de telle sorte qu'un utilisateur peut entendre de manière fiable ladite voix.　Le dispositif de traitement d'informations comprend : une unité de détection de bruit (20) qui détecte le niveau de bruit du son dans un véhicule ; une unité de détection vocale (30) qui détecte si une voix est délivrée ou non à un utilisateur ; et une unité de commande de volume (50) qui règle le volume de la voix en fonction du niveau de bruit lors de la réception en provenance de l'unité de détection vocale (30) d'un résultat de détection qui indique que la voix n'est pas délivrée à l'utilisateur, et qui ne change pas le volume de la voix lors de la réception en provenance de l'unité de détection vocale (30) d'un résultat de détection qui indique qu'une voix est délivrée à l'utilisateur.
