Obedience training is not the same as training a dog to do a 'trick' like roll over, shake a paw, or asking it to speak. There will be a future blog on this. Working with a qualified instructor is extremely important. Don't try this on your own by just 'winging it' - there are many steps to training your dog and each dog is different.
Obedience training, when done properly, teaches the dog to learn a set of drills as well as what is appropriate behaviour and what is not acceptable. The dog also learns to listen to you because YOU ARE IN CHARGE.
