1. A device for controlling an apparatus, the device comprising:
- a receiving unit for receiving speech input, an analyzing unit for analyzing the received input for recognizing a command, and an activation unit for switching the device from a standby mode, in which the device is not operational for actual control of the apparatus, to an operational mode, in which the device is operational for actual control of the apparatus characterized in that the activation unit is arranged to switch the device from the standby mode to the operational mode upon the analyzing unit recognizing an activation instruction in the received speech input, said device being arranged to determine, in the operational mode, whether any command is recognized during a predetermined attention period, the attention period comprising a plurality of portions, said device being arranged to generate an attention signal if no command is recognized in at least one of the portions and to leave the operational mode and to enter the standby mode if no command is recognized during the attention period.

Abstract
A speech input based input device (100) has a standby mode in which it can only recognize its activation instruction and an operational mode in which it can recognize commands for control of an apparatus. When the device (100) recognizes in the speech input its activation instruction it switches into the operational mode. The device remains in the operational mode for as long as commands are recognized and returns to the standby mode if no commands are recognized for a given period of time. The device according to the invention may have a signaling module (126) for producing audible signals to inform the user about the mode or mode changes of the device.

9. A method of controlling an apparatus comprising:
-
receiving speech input in a receiving unit of a device for controlling said apparatus;
analyzing said received speech input to recognize a command;
detecting an activation instruction in said received speech input;
upon detecting said activation instruction, switching said device from a standby mode in which said device is not operational for actively controlling said apparatus to an operational mode in which said device is operational for actively controlling said apparatus;
determining in said device, when said device is in said operational mode, whether any command is recognized during a predetermined attention period, the attention period comprising a plurality of portions;
generating an attention signal if no command is recognized in at least one of the portions of the attention period; and
switching said device to said standby mode if no command is recognized during said attention period. - View Dependent Claims (10, 11, 12, 14, 15)
producing in said device an audible start signal that indicates the start of an attention period during which said device remains in said operational mode.

11. A method as claimed in claim 10 wherein the attention signal comprises an audible attention signal.
-
12. A method as claimed in claim 10 further comprising:
-
determining in said device during said operational mode whether any command is recognized during a predetermined period;
switching said device from said operational mode to said standby mode if no command is recognized during said predetermined period; and
producing in said device an audible end signal that indicates an end of said attention period.

13. A method of controlling an apparatus comprising:
-
receiving speech input in a receiving unit of a device for controlling said apparatus;
analyzing said received speech input to recognize a command;
detecting an activation instruction in said received speech input;
upon detecting said activation instruction, switching said device from a standby mode in which said device is not operational for actively controlling said apparatus to an operational mode in which said device is operational for actively controlling said apparatus;
determining in said device, when said device is in said operational mode, whether any command is recognized during a predetermined attention period, the attention period comprising a plurality of portions;
generating an attention signal if no command is recognized in at least one of the portions of the attention period;
switching said device to said standby mode if no command is recognized during said attention period; and
producing in said device a repeating audible sound that indicates said attention period while said device remains in said operational mode.
