I had Wedgie when he was about six to eight weeks old and started with 'pretty boy' that is very easy for them to say, I think it was about six weeks later that he started talking, the first couple of times I wasn't sure then he got clearer and clearer, I have ADHD so talk all the time which helps when teaching budgies!!
Wedgie has a fantastic repertoire but he is camera shy, I will try to get a better one when he is not looking. [some chance] He only has to hear a word or sentence a few times and he can say it perfectly, he also remembers things that I have forgotten teaching him, he came out with "Happy Christmas" and "Jingle Bells" yesterday, he must be practicing for Christmas, he also picks up things that I say to him as a matter of course, "going shopping, be back in a minute" "there you go Wedge" and "have you got cold tootsies?" He has started biting me lately to get attention and he is jealous when I talk to my son or partner on Skype and shouts over them, bad boy but I love him to bits, he will tell you that too!
