A interesting Text to speech web app

[PointCloud]

I found a interesting text to speech web app awhile back and I just wanted to share it.   The site has a demo for non-commercial use but it has tons of voices that sound pretty good.  The USA "Will the bad guy" is my favorite.  Though the demo seems to be unlimited on the amount of phrases you could try out.  I have probable tried over 200 phrases so far.  
EDIT::Found that a lot of the voices are license to a softwares called TextAloud 3 and natural reader.  All at individual prices at like 35  bucks a pop or more not including the price of the software.  I will have to take a look at it more in depth to see if the voices install on the system as well.

I did some further digging and it appears that the personal use voices have to be used with Textaloud and Natural reader products. The voices are not for sale without these software it seems.    Meh in the meantime I am going to email the Acapela team and ask if there is just a windows based option so Vox can use it.

What you are looking for is an engine that is Microsoft SAPI compatible.  Probably SAPI 5.3 or later.
