Abstract

A voice recognition system having a mobile unit and an external server. The mobile unit includes a memory unit that stores voice model data having at least one expression set with expressions, a voice recognition unit, and a data interface that can set up a data-oriented connection to a data interface of the external server. The external server includes a database with event data having associated time data and expressions. The external server can, by comparing the time data associated with the event data with a current time, produce updated data that includes at least expressions associated with the event data of the database. The update data can be transmitted to the mobile unit. The update data can also be taken as a basis for adding the transmitted expressions to the expression set. Also disclosed is a method for operating a voice recognition system.
