The number 1 factor that determines success in this area is the underlying talent of the student. This particular skill, in my experience, is similar to musical talent. We cannot change the talent we are born with, but we can learn techniques that may or may not lead to improved pronunciation. The technique that clicks for each student will also vary and may change based on other variables (held constant or changing).
