The 1962 Canon, according to the "Ritus servandus in celebratione Missae", IX, of the 1962 Roman Missal, is spoken in a tone described as "silentio", a word that in the context of liturgy is officially translated into English as "quietly". The English version of Nicholas Gihr's book on the Mass translates "secreto" as "silently", but explains that it means that the Canon is to be said not in absolute silence but "in a voice so subdued that the celebrant may hear himself, but not be heard by those around him". However, the rubrics of the Canon indicate that, when saying the phrase ""Nobis quoque peccatoribus"", he raises his voice a little ("elata aliquantulum voce"), while the final ""Per omnia saecula saeculorum" is to be spoken understandably ("intelligibili voce").
