Display apparatus and method of controlling a display apparatus in a voice recognition system

A display apparatus comprising:

• a voice input configured to receive a user's voice to be used to control the display apparatus;
• a communicator configured to communicate with an interactive server;
• a storage configured to match a command and control information in order to store the same;
• a display;
• and
• a controller configured to transmit the user's voice via the communicator to the interactive server while determining whether the user's voice input via the user input is a pre-stored command,
• when the user's voice is not a pre-stored command in the storage and when control information which corresponds to the user's voice and first guide information are transmitted from the interactive server, the first guide information guiding the pre-stored command capable of performing the same function as the user's voice, the controller being configured to perform a function of the display apparatus based on the control information transmitted from the interactive server and to control the display in order to display the first guide information.

A method of controlling a voice recognition system comprising an interactive server and a display apparatus, the method comprising:

• receiving a user's voice by a display apparatus;
• transmitting, by the display apparatus the user's voice via the communicator to the interactive server while determining whether the user's voice input via the user input is a pre-stored command;
• transmitting, by the interactive server information to the display apparatus by generating at least one of control information which corresponds to the user's voice and first guide information, the first guide information guiding a pre-stored command in the display apparatus that can perform the same function as the control information;
• and
• in response to the user's voice not being a pre-stored command in the display apparatus, performing, by the display apparatus a function based on control information transmitted from the interactive server and displays the first guide information.

A display apparatus comprising:

• a communicator configured to communicate with an interactive server;
• a storage configured to match a command and control information in order to store the same;
• and
• a controller configured to transmit the user's voice via the communicator to the interactive server while determining whether the user's voice input via a user input is a pre-stored command,
• wherein when the user's voice is not a pre-stored command and when control information which corresponds to the user's voice and first guide information are transmitted from the interactive server, the first guide information guiding the pre-stored command capable of performing the same function as the user's voice, the controller being configured to perform a function of the display apparatus based on the control information transmitted from the interactive server and configured to control a display of the first guide information.
