One of the cool things I've just found on the Intervoice
developer portal site is a sample application they have recently put up. More
details (including the phone number to call) are at http://developer.intervoice.com/salt/locatorapp.html.
You can dial into it, give it a zip code (or city/state) and it will return the nearest
ATM or bank information. It's currently running on beta software and so is occasionally
unstable or unavailable - but it really is a live running SALT telephony application.
This stuff isn't vaporware any more!
The application is a good example of what's possible, but there is probably still
some room for improvement. There seemed to be a couple of places where synthesized
speech is used where I'd expect a recorded prompt. There's also an audible click at
the end of each prompt which I'd hope that they will be able to improve upon. Certainly
our internal applications don't seem to exhibit this behaviour. All the same, it's
a good solid demonstration.
