Casey's Mom is absolutely correct, Not all birds who have the capabilities choose to talk. But they are still very lovely entertaining pets anyway. You might try putting meaning to actions and things Like when you feed him Ask him are you hungry, want something to eat etc. and then give him some food. When you change his water do the same. Are you thirsty, want some clean water... When you get up in the morning and check on him for the first time, Tell him "good Morning" How are you. When you put him to bed, tell him , Night Night or its time for bed. etc. I don't sit and just repeat things to my birds, I carry on conversations or we'll sing songs And I sing different songs not just the same one over and over, So you might try showing meaning for what your saying so he can associate the words to actions or objects.
As far as the squawking in the mornings, That's what birds do. They are waking up their flock calling everyone in to get up and get on with your (their day) Its their way of communicating, granted it can be fairly annoying at times, especially when you want to sleep in, but such is life as a bird owner.
You might consider yourself fortunate that he only squawks in the morning, Mine squawk morning and Night just as its starting to get dusk. They're calling the flock home making sure everyone is in their rightful and safe place for the night. And trust me, with 12 birds all going to town at once. You have a real quiet house with just one little quaker

You might get some reprieve if you will really work at Saying Good Morning Or How are you this fine morning And do it every single day. Switch it back and forth to give him his choice to pick up. When they learn to associate that phrase with Getting up in the morning, A lot of times you'll here Good MORNING instead of a squawk which is much more pleasant to wake up to.
My Blue crown Conure Wembley is very good at saying GOOD Mornink... And she starts saying it the minutes she hears movement in the house in the morning. And its such a cute little voice that it has a very cheering effect.
Several of my other birds and especially my Citron Cockatoo who is a screamer...also tells me Night Night when he's ready to be covered up for the night.
He also says what's your problem after he's gone through a session of screaming. His previous ownere obviouly said that to him a lot So my point is, just keep talking, you'll be surprised at when they come up with just little things
You might also try using a little higher pitched tone and excentuate different parts. Try not talking in a monotone voice.
But then again as was said, some birds would rather watch and have you entertain them.
Here's a little example of what happens here, I have a quaker "Paddie Wack" so I often sing "This ol' Man" and I really emphasize "Knick Knack Paddie Wack" When I do that she gets excited and chirps like HEY that's me" Well now Wembley the blue crown just started saying Knick Knack Paddie Wack. I've been singing this song off and on for 3 years now. So you just never know when they'll say something, And when one starts saying it pretty soon others will pick up on it. When Wembley says Knick Knack Paddie Wack, Paddie Wack chirps... So its rather fun.
And you just never know what's going to trigger it for which bird. Paddie Wack doesn't talk a lot. But when ever she hears me cough or sneeze she'll call the dog..."here Wicket, cough cough" "Here Wicket" So evidentally I must have been calling the dog while I was coughing or sneezing at one time or another and that's what triggered it for her.
Peek a boo is a big hit around here too...I have 4 or 5 Peek a boo'ers in the house, and when one starts eventually they all will start in and wait till each other has finished it And Hello when when the phone rings.
So don't be too discouraged, Just enjoy him for what he is a cute little mischivious bundle of green fluff.
