This assignment can be done by the graphical design of this user interface.
- the voice commands entered can be converted into an infrared code set and then graphically assigned to the device to be controlled on the monitor.
- Today's graphical user interfaces allow, of course, changes in the code set as well as changes in the shape of the graphical user interface to be carried out by commands, e.g. can be entered via the keyboard or a mouse. Entries made can be saved as a protocol.
- the PC can also generate acoustic feedback to the user.
- the PC also handles complex enterable, storable and viewable 'operations, which can be executed on a respective input through to an arbitrary later time.
- a generic system for the voice-controlled remote control of electrical consumers is characterized according to claim 7, characterized in that the remote control network has an infrared transmission path, that the PC has memory means for storing an IR code set and coding means for coding each control command generated by the implemented speech recognition program in accordance with the received voice command in the form of IR-coded signals and means for transmitting the IR-coded signals via the remote control network to the respective electrical consumer and that the consumers are assigned an infrared receiver which receives the respective IR signal transmitted via the remote control network and the IR transmission path.
- a conventional input device such as a keyboard, can be used to enter an IR code set, change it and assign it to a respective consumer.
- One or more electroacoustic transducers can be connected to the speech channel interface of the PC, whereby several speech channels can also be distributed over several rooms.
- the remote control network can either lead to the individual consumers in the form of an star or can also have a structure.
- the remote control network can advantageously also have an optical fiber line via which the IR control codes can be transmitted directly.
- a commercial one is used for speech recognition.
- PC implemented speech recognition system This speech recognition system can pass on the information obtained by the speech recognition based on the entered voice commands to other programs. This information is recorded and with the possible remote control commands for controlling the electrical ones Compared consumers. As soon as a command is recognized, this command is searched for in the memory, and there is, for example, the information that the radio receiver is to be switched over and, if appropriate, additionally the information in which room the radio receiver is located. Then the associated infrared-coded signal is transmitted to the corresponding room and emitted there, which leads to the switching of the radio equipment.
- the method according to the invention and the system according to the invention make it possible to carry out a combination of a voice input unit with a sequence control in the simplest way.
- the method and the system also enable a control sequence to be delayed. For example, before starting a vacation, the user can program the time and program any sequence control based on the programmed time for the duration of his absence.
- An additional advantage of the system according to the invention is that the user can check on the PC monitor at any time which input he made and when.
- FIG. 1 shows a block diagram of a system according to the invention for the voice-controlled remote control of several consumers with a star-shaped remote control network as the first embodiment of the invention
- FIG. 2 shows a second embodiment of the system according to the invention for voice-controlled remote control of a plurality of electrical consumers, in which the remote control network has a structure
- FIG. 3 shows a third embodiment of the system according to the invention for voice-controlled remote control, in which the remote control network provides for the transmission of infrared signals via a glass fiber line;
- FIG. 4 finally shows a simplified embodiment of the system according to the invention for voice-controlled remote control of several consumers, in which the consumers are only switched on and off.
- a standard PC 1 which has a CPU 11, a monitor 12 and a keyboard 13 in the usual way, has an electro-acoustic converter 100 via a voice channel interface 14 and a remote control network 50 via a remote control interface 15 connected.
- the electroacoustic transducer 100 defines a voice channel 110.
- a voice recognition system is implemented in the PC 1, which recognizes the remote control voice commands that reach the electroacoustic transducer 100 via the voice channel 110 and from there to the CPU via the voice channel interface 14, and which through Speech recognition information can be passed on to other programs.
