I believe that it does not matter how loud you pray, what matter, is what and why you pray your prayer. Also, what matters is if we mean, what we pray or say with our mind. Do we mean it in our hearts?
First, start your prayers with praysing and worshiping God, with a psalm, a song, or a hymn. Spend some time worshiping and praising him for who he is, for his love, power, wisdom, holiness, greatness, because he is the creator of everything, and is worthy to be praised.
Also, give thanks to him, for what he has done or what he is doing in your life, and for what he has given you.
Then, offer your petitions to him, and ask him to help you with your problems, or to satisfy your needs.
