seriously, buy a tape recorder and just play it continuously to your bird. at least then, it will be your own voice he's hearing and not just some random person saying 'hello' over and and over again. i'm sure repitition is good for them to learn, but i paid $11.99 for this? the entire cd is made up of random words or phrases all about 3-5 seconds long. the idea is to choose the one you want your bird to learn and then put the that track of the cd on repeat. it makes sense, but really, couldn't you do it yourself for free? also, alot of the words are things i wouln't want him to learn anyway, just random stuff you wouldn't normally even say yourself.
