A city information system operating over the telephone

We present a voice controlled inquiry system designed for operation on the public telephone network. Its goal is to provide residents as well as visitors of a city practical information of various types, such as programs of cinemas and theatres, overview of local sport events, timetables of city and regional transport and opening times of public or private institutions. The InfoCity system, as it is named, operates on a system-driven dialogue platform with an isolated-word style input (using a vocabulary of some 220 words and short phrases) and with a TTS generated output. The InfoCity framework has been adapted for serving the city of Liberec. It has been the first automatic information system of this type developed and tested in Czechia.
