dialogue system demo wanted

[Laszlo Toth <tothl@xxxxxxxxxxxxxxx>]

Dear List,
I'm looking for sample recordings or videos from working spoken dialogue
systems. Preferably in English and on some "classic" application domain
like timetable information system or ticket ordering. I would need it only
to demonstrate my students how a conversation with a dialogue system
sounds like - and surspisingly, I can hardly find such samples on the net (or
rather, I fail to filter out the irrelevant hits...).
Thanks,
