No, but neither can anyone that isn't a telepath. What you do, once I open a channel, is just think your reply to whatever I just said in my general direction. It seems weird at first, but once you get the hang of it, it's the easiest form of communication you'll ever see.
As for what else I can do, well. Telepathy and telekinesis, if you want a broad general idea. What I can do with it is a little more complicated. With telepathy, besides reading/communicating with minds, I can read psychic impressions left on objects or places as a sort of audio/visual "memory" or sometimes just a feeling. I used to be able to peak into the future and see different possible futures. I can cast illusions so real you'd swear they were reality. I can track people by psychic signature pretty much anywhere in the world.
With the telekinesis, I can move stuff with my mind. Big stuff, like cars, and little stuff, like nudging the molecular structure of something. For instance, if you'll forgive me a little blasphemy, you give me a jug of water and I'll hand you back a jug of wine. I could also probably subtly degrade the structural integrity of things that way, but for something like that, I might as well just rip it to bits. Same end result. I can also use it to combine motes of dust into physical simulacra, but I prefer to just use my psychic illusions for that, since I can easily tell someone's mind that an imaginary box has the same weight and texture of a real box. One of my favorites in a fight, though, is to add a telekinetic field around my arm while I'm punching someone to simulate enhanced strength.
So...a lot. I'm sort of a high level psion.
OH. And I can fly. I think that one's my favorite.
