You are so right, Kimba. Although I've read, and understand, that one should never adopt a bird for the sole purpose of acquiring a 'talking' bird, I have to admit that I was very excited about the prospect of communicating with my Grey. She was quite average with regards to her timing, and began forming words just after her first birthday.
Today she talks up a storm. She's typically silent when strangers are present, but is getting more and more verbal when others are in the house - especially if we ignore her.
She does scream and whistle quite loudly, but I have recently purchased a training video which I'm hoping with train 'me'

to break the bad habits.
I had researched training methods for getting her to talk, but the natural way, described by Kimba, of just communicating with her in the same way that you may communicate with a child, is the most effective, enjoyable, and fun way to get your bird to really talk up a storm!
It typically takes her a week or two to actually start using a word or phrase that she has picked up and is interested in remembering. I'm always tickled pink when I realize that she's beginning to say something that I incorporate into my daily routine. At first, you may not recognize what they're saying, but soon enough you realize when and where they picked it up.
Our morning routine is probably the one that has added the most words and phrases to Lucy's vocabulary. Because I ask questions, tell Lucy exactly what I'm doing, and am very happy and excited when I react to her, she has come to learn, understand, and speak the following words and phrases:
"Do your poo poo" (Lucy must do her 'poo poo' before she can come off her cage onto Mommy's hand)
"Step up"
"Let's go take a shower" (Lucy stands on the shower door every morning while I shower)
"Wanna come out with Mommy?"
"Lemme get some water"
"It's good, good food" "It's good stuff" "Mmmmmmmmmm" "It's got juice" (Referring to her apple)
"Eat your good food"
"Eddie, Eddie, come here buddy" (Talking to our Burman Siamese)
Once I tell her I have to go to work, and that she be a good girl:
"You be good girl"
"Good Bye Lucy" "Good bye"
"I love you"
"Be good girl"
"Bye Lucy"
I could go on and on, but I'd better bring this rather long post to a close. Just talking to them naturally while doing your every day routine will bring both of you joy, and further enhance the bonding process.
