answer:I don’t know the specifics of his exact machine, but I once helped make a bit of software that did a similar thing. Basically, you get the entire alphabet, and you record what each letter sounds like seperately. You then say each letter with a different vowel at the end of it, to get variations of the recordings. Then all you need to do, is get the computer to load the correct individual sounds one after another to make words, depending on what text was input in to the computer. As for playing WOW with him, sadly I don’t think it would be cool, as he probably would not be able to do much. I hear he is in a worse condition than usual lately.
