Lots of people have lots of ideas about what it means to hear God, and what it means to pray. Quakers sit in silence and speak as the spirit moves them, saying whatever they intuit, and they consider that to be hearing God. Native Americans pray in the twilight before dawn (and at other times, too, but in every tradition I know of, that time of day is best. According to one of my herbalism teachers, who is Choctaw, that's the most powerful time). Sufis and Buddhists chant, medieval monks did the same, Muslims pray five times a day (including that before dawn time) in a way that includes yoga-like exercise. The experience itself becomes not only addressing God, but hearing God, being in the presence of God.
Even the Lord's Prayer was originally a body and chanting prayer. The words in translation sound like just something to recite by rote in a stuffy, staid church service, and that's what they've become, but the words in Aramaic are a chant that opens up the throat chakra, hold many more layers of meaning than any translation, and it was probably done with bodily positions mirroring the words. In the New Testament, Jesus introduces the prayer by saying if you don't know how to pray, pray like this. We then get the words of the prayer, but he wasn't just telling his disciples to say those words, he was demonstrating how to do it physically, and that part is completely lost in writing.
In any case, hearing God may depend on how you pray, and what you do to bring in that experience... and also what kind of experience you would consider to be a response. And there are lots of ways you could go about it.
