Barnes' Notes
I have called upon thee for thou wilt hear me, O God - The meaning of this is, "I have called on thee heretofore, and will do it still, because I am certain that thou wilt hear me." That is, he was encouraged to call upon God by the conviction that he would hear his prayer, and would grant his request. In other words, he came to God in faith; in the full belief of his readiness to answer prayer, and to bestow needed blessings. Compare John 11:42; Hebrews 11:6.
Incline thine ear unto me - See the notes at Psalms 17:1.
My speech - My prayer. The reference here, as in Psalms 17:1, is to prayer "uttered" before God; and not mere mental prayer.
