"Aphasia" (was Re: use-livecode Digest, Vol 171, Issue 44)

Unfortunately, it is all rather more complicated than either Richmond or Peter suggest. There are many more contributing areas than Brocas, and what Peter describes doesn't appear to be aphasia at all, but rather a pathology of semantics or word finding. 

It's not possible to be more specific without more information, and my advice would be to speak with a neuropsychologist before coding. You could spend a lot of time comparing wavs and coming up with a solution to the wrong problem. 

Best wishes

The idea is that her family can put together sets of words where each word is spoken by the app whilst displaying a relevant picture and optionally a short video clip illustrating the correct mouth shape when saying the word.  The app displays the word in a very large font with a picture, then the app says the word (with the option to see a mouth shape video clip).  The user responds by trying to say the same word and (the thing I can't do yet!) the app gives the user a percentage score that represents how closely the user matched the sample word. If the user's score is above a variable threshold, the user sees a smiley face, otherwise a sad face!
