How can he talk to other people?

Now that you have seen that he is capable of travelling at more distances and possibly talking with other people when he  is travelling with it in the air, now that we have mentioned in the last pages that he has programmed that comically on a holographic event.... Now since then he actually inserted some high technological images inside the reactor when he actually made it he inserted many speaking technologies that graphically gathered the suits ability to communicate

he also inserted many features such as:
 * Taking Visually
 * Picture Viewing
 * Holographic Displaying into a window PC
