You must read each line OUT LOUD repeatedly. NOT in your head. Do not paraphrase, or you'll fall into bad habits with your lines. Write lines on note cards, and work on that line. Slowly wean yourself from peeking at the words you wrote down. Personally, I like to memorize before I go to sleep, because the lines tend to be what I'm thinking about when I fall asleep. Hence, they stick in my head. Repetition is really what it all boils down to.
I like to have it typed on large note cards, then bind the cards in order. I read aloud with flavor (not word calling) each card complete. When that one is done, I go to the next and repeat.
