A speech dialog system wherein a process for automatic control of devices by speech dialog is used applying methods of speech input, speech signal processing and speech recognition, syntatical-grammatical postediting as well as dialog, executive sequencing and interface control, and which is characterized in that syntax and command structures are set during real-time dialog operation; preprocessing, recognition and dialog control are designed for operation in a noise-encumbered environment; no user training is required for recognition of general commands; training of individual users is necessary for recognition of special commands; the input of commands is done in linked form, the number of words used to form a command for speech input being variable; a real-time processing and execution of the speech dialog is established; and the speech input and output is done in the hands-free mode.

Process for automatic control of one or more devices by voice commands or by real-time voice dialog and apparatus for carrying out this process

In normal operation, a control or regulating device controls vehicle rear wheel steering in accordance with freely-selectable specifications. If a malfunction of the control or regulating device is detected, the latter becomes inoperative immediately. A piston-cylinder unit drivingly connected to the front wheel steering and a piston-cylinder unit drivingly connected to the rear wheel steering are simultaneously positively coupled to one another, with the result that the rear wheel steering is actuated positively via the front wheel steering.
