Abstract
This paper describes the Automatic Switchboard Operator system and experiences and improvements based on data collected while full operation of the application. Automatic Switchboard Operator is a voice dialogue application whose purpose is to answer phone calls and transfer the calls to the requested person. Called person is recognized according to a speech grammar which has key effect on successfulness of the system as a whole. After several months of full operation of the application, the speech grammar was made more robust in order to accept more utterances and filter out substantial information, i.e. a filler model was introduced.
