The acronym OVIS stems from “Openbaar Vervoer InformatieSysteem” (Dutch for: Public Transportation Information System). This was a speech-input and speech-output system for providing information about train travel over the telephone.

The system was used experimentally for a short period, during which the OVIS corpus was collected at the University of Groningen — see www.let.rug.nl/vannoord/Ovis
