Fields of Application
Thanks to modern technology, physically handicapped persons are now able to cope on their own with
most everyday situations.
The many different ways of operating modern devices, however, means that the handicapped person
has not only frequently to rethink but often enough has to change control units.
Voice-control is a mobile device for controlling and operating numerous appliances and equipment
designed specifically for the handicapped, as well as for household technology, communication and
entertainment electronics.
Voice-control converts spoken commands into signals to control equipment designed specially for this
purpose. The signals are output by:
•Infrared transmitter, e.g. for television, video recorder, hi-fi equipment, telephone, and lighting
only for Order No. 0535 00
•Radio transmitter, e.g. for house doors, elevators, intercom and alarm equipment
•Wired interfaces, e.g. for electrically operated wheel chairs and motorized adjustable beds
Voice-control can be operated as an installed device from the mains (the power supply unit is also the
accumulator charger) or as a portable device with accumulators/batteries.

Overview of Functions
With the Voice-control, up to 64 different commands can be stored. Simple commands such as "on",
"off", "left", "right" etc. can be can be added to any other command and can therefore be used more
than once in combination. The Voice-control sends commands like "Turn on TV" automatically via the
selected interface to the desired device. Each command can initiate actions on various devices at the
same time. For example, as soon as the phone rings, the volume on radio and TV are turned down.
The range of the Voice-control functions depends on the configuration of the device. The Voice-control
is configured using PC software supplied with it.
Configuration consists of:
•Defining the menu structure
Choosing the menu items, branches and actions
•Setting the parameters for actions
Transmission type and value
•Training the voice pattern
Having copied the configuration data into the Voice-control, the device can be operated entirely
without PC. The commands are given by speaking, using the voice pattern recognition. If there are
problems of recognition in operation, it is possible to retrain every command word on the pilot. Nurses
can operate the Voice-control per control keys.
All menu items and actions are shown on the display and can also be output in plain text on a
loudspeaker.
Operating the Voice-control
Operation by Spoken Commands
Voice-control is normally operated by means of spoken commands. The user speaks the commands
of the menu tree one after the other to achieve the desired action.
The figure below shows the chain of commands necessary to dim a lamp defined as light number four.

Voice-control 06/97 Page 3 of 6
The menu tree for this might be:
Level 1 Level 2 Level 3 Level 4
Although the user needs four commands to dim the lamp, the menu structure allows many actions
using only a few command words. The plus/minus pair of commands, for instance, can change the
volume on hi-fi equipment or the angle of inclination of the back of a chair.
With command words 0-9, telephone numbers can be composed, socket-outlets can be numbered, or
television channels can be chosen.
Operation by Command Keys
Because the Voice-control is trained to recognize the individual voice pattern, operation by a third
person is only possible by means of command keys. Speaking a command is the same as selecting a
command with the scroll key and confirming it with the OK key on the pilot or on an external keyboard.
By connecting special operating peripherals ( suck/blow switch, foot switch, head switch,...) to the
keyboard interface, the Voice-control can also be operated by people with a speech impediment.
Configuration Software
The Voice-control is delivered together with configuration software, allowing the Voice-control to be
adjusted to suit the individual. The software can be run on a standard PC under MS-Windows. (CPU
Intel 80386 or higher, RAM 4 MB, MS-Windows V3.1 or higher)

Menu Configuration
The structure of the command menu is pictured graphically on the computer screen.
A maximum number of four menu levels is available. The individual commands can be chosen from a
word list.
The vocabulary in the word list is contained in the pilot for the speech output function. When a
command initiates an action (i.e. the output of control signals), the data must be parameterized in a
screen.
Training the Voice Pattern
The selected commands are trained on the PC with the help of the Voice-control. Each word is spoken
several times so that a common voice pattern can be analyzed. The voice pattern of the word is part
of a neural network that allows speech to be recognized in operation. The voice patterns are stored in
the pilot. Individual words can be retrained on the Voice-control even without a PC and configuration
software.
