There are no guarantees that any parrot will talk, even the ones that are known for talking like a macaw or a cockatoo. But, if you talk to him every time and say "hi baby" whenever you walk in the room, he may copy you because he is used to hearing you. I wasn't even trying to teach my cockatiel to talk, but he just picked it up and now he can say "hello" and "good boy"! Good luck in training Teddy to talk and keep us posted!
