Language learning through play is usually the best way. For me, access to the hearing world was accomplished largely through literacy. Access does not mean mere physical presence or the ability to speak. It means being spiritually a part of a literate society. It is the ability to function and participate independently on one's own terms and within one's natural abilities.
Access is the ability to fulfill one's own individual potential without artificial constraints.
Access is drifting down the Mississippi on a raft with Tom Sawyer and Huckleberry Finn. It is retreating across the frozen Russian steppes with Napoleon's exhausted troops. It is understanding how the brilliantly beautiful butterfly is magically transformed from an ugly caterpillar. I can marvel over Christ's resurrection. I am able to disagree with Aristotle's views on human nature.
