I have two problems with your sounds: First, our blind schedule is totally different and 2) the voice is just way too mechanical. Its a great idea to do this, but it would be better to have a real voice. I was tempted to make some sounds with that same voice from that webpage (AT &T, right?) but I just felt that the voice didn't seem natural enough. Its a good idea, but try with your own voice, or some girl's voice (I betcha my 2 year old girls voice would be cute, if only I could convince her to say all those numbers in a sitting... short attention span has she)
