This verse is said everyday all across the world as part of the liturgy of the hours. I'm not sure which translation is used for the liturgy of the hours, but in English we say "O Lord open my lips and my mouth shall declare your praise." And this is also split between the two choirs.
Lord, open my lips, and my mouth will speak out your praise.
Through the liturgy of the hours, along with Mass (or Divine Liturgy for the Eastern Churches) the Church never stops praying. Of course there are myriad other forms of prayer such as rosary going on, but at any given moment somewhere in the world two things are happening liturgy of the hours and the Holy Sacrifice of the Mass. The Church never stops praying, we pray continuously.
Formalized prayers of the Church are great way to glorify God and to continuously declare His praises. However, the Lord opens mouths and we often find other ways to speak His glories. The best ways I can think of is evangelization. All the Apostles went off to preach the love and the glory of God. Sts Paul and Peter most come to mind when we think of this, but lets not forget St Thomas who went to India nor Sts James, Matthew, and John whose writings are still used to spread the Gospel and continue the perpetual adoration and worship of God. I could name countless other saints, since of course by their nature saints declare the praises of God.
May God bless all who read my ramblings,
