Right. You can't just get cochlear implants and then say you're "cured" or like a hearing person (speak/hear).
A person with cochlear implants may hear, but can he/she understand what he/she is hearing?
There's a difference between look and observe. You can look at a building, but to observe the building will allow you to be able to say how many windows there are, what color the bricks are, how many stories there are, etc.
You start hearing... good. But you gotta work on being able to recognize what you're hearing. From there, you also work on your speech skills because that comes from knowing what you're saying too.
