Hi I've had my Alex for a year since 6 months, interactive noisy lives out his cage. I try 24/7 as much as I can to say words, Hello, pretty boy, etc, but every word comes out a whistle word not letter words. Hi mimics the word into a whistle sound. It's so annoying, can Alex talk words like other parrots. He has his own conversation on his own babbling away with all kinds of sounds but words. What advice can someone give me to help my Alex talk.
