EASY BY VOICE stands for "Environmental Control Access System by Voice" and is a new system making it possible to operate practically all equipment used in daily life by giving spoken commands. 
In particular, all electrical installations in a house or apartment can be controlled by means of this system. Simple examples of this include the switching on and off of lights, the opening and closing of blinds, etc. 

Above and beyond these simple cases, the system is also able to fit together separate basic functions into complete processes, which can likewise be controlled by single words of command. Moreover, it is possible to make queries about the status of certain objects. 

For example, a person who is currently in the living-room can enquire about the status of the lighting in the cellar. Depending on the fittings in the house or apartment, it is also possible to open and close doors or to turn taps on and off. 

Moreover, virtually all types of home entertainment equipment can be operated with EASY BY VOICE. This includes televisions, hi-fi systems and video recorders, provided they can be operated by infrared remote control. In this case, EASY BY VOICE takes over the function of the remote control.
The third important area which can be controlled by EASY BY VOICE is that of telecommunications. In this way it is possible to take incoming calls by means of a spoken command, or to make a call using the telephone book function of EASY BY VOICE.

The core of EASY BY VOICE is the voice recogniser. The voice recogniser used has the special characteristic of being able to recognise commands regardless of who the speaker is. This makes a tedious and time-consuming training of the speech recogniser unnecessary. After approximately 1 hour's work with the system, a new user will be so comfortable with it that he will be able to operate it freely. 

Another considerable advantage of the system's ability to function without dependence on individual voice patterns is that the command structure can be adjusted to new conditions in the shortest time. In order to control the house fittings, EASY BY VOICE uses any available house automation system, such as "Instabus" or EIB. In contrast to many infrared-based systems, the connection to such a system makes it possible to operate switches in all rooms and - as already mentioned - to make queries about the status of installations in other parts of the house. This means that switches can be operated from any area of the house or apartment without the need for visual contact to the object to be switched on or off. Home entertainment equipment is controlled by a specially developed infrared transmission module, which is able to save a practically unlimited number of infrared codes. 

Furthermore, the module can combine individual functions to form a sequence, for example, a single command would be enough to switch the television off and the radio on. The user can let his imagination run wild when combining commands, i.e. the sequences can be made as complex as required.

A traditional telephone connected to an equally traditional ISDN telecommunications box is used to convey commands to the system. For this, the system uses an internal SO bus (= internal ISDN cable). This means that no telephone costs arise when the system is used within the house or apartment. The "input equipment" preferred is a cordless telephone corresponding to DECT standards, enabling the user to move freely in the apartment.
