In this article we present a voice enabled call center which integrates our basic and applied research results on Hungarian speech recognition. Telephone interfaces, data storage and retrieval modules, and an intelligent dialog descriptor and manager module are also parts of the system. To evaluate the efficiency of the recognition and the dialog, a voice enabled call center was implemented and tested under real life conditions. This article describes the main modules of the system and compares the result of the field tests with that of the laboratory testing.
