First Claim
1. A display apparatus comprising:
- a signal receiver configured to receive a broadcasting signal;
a display configured to display an image based on the received broadcasting signal;
a voice receiver configured to receive a voice spoken by a user;
a first voice recognizer configured to be supplied with electric power when the display apparatus is in a standby mode, and determine, while in the standby mode, whether a sound characteristic of the received voice corresponds to a reserved word selected from among a plurality of reserved words;
a second voice recognizer configured so as not to be supplied with electric power in the standby mode, and to be supplied with electric power when the sound characteristic of the received voice corresponds to the selected reserved word, and to determine whether a command of the received voice is the selected reserved word; and
a controller configured to control the preset operation to be performed when the command of the received voice is determined as the selected reserved word,wherein the reserved word is a predetermined word for instructing the display apparatus to perform a preset operation, andwherein the reserved word comprises a first reserved word and a second reserved word, and the first voice recognizer, when the display apparatus is in the standby mode, determines whether the sound characteristic of the received voice corresponds to the first reserved word, and determines whether the sound characteristic of the received voice corresponds to the second reserved word when the display apparatus is in a normal mode.

8. A method of controlling a display apparatus for displaying an image based on a received broadcasting signal, the method comprising:
-
receiving a voice spoken by a user with a first voice recognizer, which is supplied with electric power when the display apparatus is in a standby mode; determining, while in the standby mode, whether a sound characteristic of the received voice corresponds to a reserved word selected from among a plurality of reserved words; with a second voice recognizer, which is not supplied with electric power in the standby mode and is supplied with the electric power when the sound characteristic of the received voice corresponds to the selected reserved word candidate, determining whether a command of the received voice is the selected reserved word; and performing the preset operation when the command of the received voice is determined as the selected reserved word, wherein the reserved word is a predetermined word for instructing the display apparatus to perform a preset operation, and wherein the reserved word further comprises a first reserved word and a second reserved word, and the determining whether the sound characteristic of the received voice corresponds to the reserved word comprises;
determining whether the sound characteristic of the received voice corresponds to the first reserved word in the standby mode; and
determining whether the sound characteristic of the received voice corresponds to the second reserved word when the display apparatus is in a normal mode. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A display apparatus comprising:
-
a signal receiver configured to receive a signal;
a display that displays an image based on the signal;a sound receiver, configured to receive a voice;
wherein the display apparatus determines a current operation mode;a first voice recognizer configured to be provided with electric power when the display apparatus is in a power saving mode, wherein the first voice recognizer is configured to determine whether a sound characteristic of the received voice corresponds to a reserved word selected from among a plurality of reserved words; and a second voice recognizer configured to be supplied with electric power when the sound characteristic of the received voice corresponds to the reserved word and to determine whether the sound characteristic of the received voice corresponds to the reserved word, wherein if the current operation mode corresponds to a first operation mode, the first voice recognizer determines whether the sound characteristic of the received voice corresponds to a first reserved word, wherein if the current operation mode corresponds to a second operation mode, the first voice recognizer determines whether the sound characteristic of the received voice corresponds to a second reserved word, and wherein a number of commands corresponding to the second reserved word may be greater than a number of commands corresponding to the first reserved word; and
a controller configured to control the preset operation to be performed when the received voice is determined as the first or second reserved word, andwherein the reserved word is a predetermined word for instructing the apparatus to perform a preset operation.
