1. A method for controlling one of an information system during the output of stored information segments via a signaling device ( 50 a ) and a technical device (G) via an initiated action ( 50 b ), wherein (a) useful information is stored in a database ( 32 ) for being requested, from which information at least one information segment is specified as a first data segment (W 1 ) via a first voice signal (s a (t),s a (z)) and is provided via a control output ( 20, 40, 50 ; 50 a ) or is converted ( 50 b ) into a control signal for said technical device (G); (b) the information is organized in said database such that an initially limited first information area ( 32 a ) of stored information is accessible ( 4, 4 a, 4 b ) to said voice signal, for selecting said specified information segment therefrom; (c) a further information area ( 32 b, 32 c, 32 d ) of said database ( 32 ) is activated ( 59, 70, 4 c, 4 d ) as a second information area, if said first segment (W 1 ) corresponding to a first voice signal segment (s 1 ) of said first voice signal (s a (t) is not contained in said first information area ( 32 a ).
