Robust speech recognition with data bank accession organized by semantic attribute

aaaabaa,bb,c,dc,daaA method for controlling an information system during the output of stored information segments via a signaling device. Useful information is stored in a database for being requested, from which information at least one information segment is specified as a first data segment (W) via a first voice signal (s(t),s(z)) and is provided via a control output or is converted into a control signal for a technical device (G). The information is organized in the database such that an initially limited first information area of stored information is accessible to said voice signal, for selecting the specified information segment therefrom. A further information area of said database is activated as a second information area, if the information segment (W) corresponding to a first voice signal segment (s) of said first voice signal (s(t) is not contained in said first information area. When accessing information of the database, a robust word recognition is obtained and the request is successfully processed within a short time.
