Claims (4)

  1. A system comprising: a server (100); and a display apparatus (200), comprising: a display; a voice recognition unit (210); a communicator (220) configured to communicate with the server (100); and a processor configured to: determine whether a voice signal received through the voice recognition unit (210) is a control signal for controlling operation of the display apparatus (200), or is a signal for at least one of a function and an operational state of the display apparatus (200); based on the voice signal being determined as the control signal for controlling operation of the display apparatus (200), perform an operation corresponding to the control signal; and based on the voice signal being determined as the signal for at least one of a function and an operational state of the display apparatus (200): control the communicator (220) to transmit the voice signal and characteristic information of the display apparatus (200) to the server (100), and receive a response signal from the server (100) through the communicator (220) and process an operation (15) corresponding to the response signal, wherein based on the response signal from the server (100) including one of a guide message and a diagnosis result, the processor is configured to process the operation (15) corresponding to the response signal by controlling the display to display the one of the guide message and the diagnosis result; wherein the server (100) is configured to: receive the voice signal and characteristic information of the display apparatus (200) from the display apparatus (200); and transmit the response signal to the display apparatus (200), wherein the response signal is generated according to a manual corresponding to the characteristic information and the contents of the voice signal.
  2. The system as claimed in claim 1, wherein the characteristic information of the display apparatus (200) includes at least one of panel information, type information of the display apparatus (200), user region information, and use time information.
  3. A control method of a display apparatus (200), the control method comprising: determining whether a voice signal is a control signal for controlling operation of the display apparatus (200), or is a signal for at least one of a function and an operational state of the display apparatus (200); based on the voice signal being determined as the control signal for controlling operation of the display apparatus (200), performing an operation corresponding to the control signal; and based on the voice signal being determined as the signal for at least one of a function and an operational state of the display apparatus (200): transmitting the voice signal and characteristic information of the display apparatus (200) to a server (100), and receiving a response signal generated according to a manual corresponding to the characteristic information and the contents of the voice signal from the server (100) and processing an operation (15) corresponding to the response signal, wherein based on the response signal from the server (100) including one of a guide message and a diagnosis result, the method comprises processing the operation (15) corresponding to the response signal by displaying the one of the guide message and the diagnosis result.
  4. The control method as claimed in claim 3, wherein the characteristic information of the display apparatus (200) includes at least one of panel information, type information of the display apparatus (200), user region information, and use time information.

Description

Apparatuses and methods consistent with the embodiments relate to a voice recognition system, a server, a display apparatus, and control methods thereof, and more particularly, to a voice recognition system, a server, a display apparatus, and control methods thereof which processes a corresponding operation according to a response signal generated by recognizing a spoken voice. US 2014191949 A1 discloses a display method and apparatus for controlling a voice recognition system. When a user's voice for controlling the display apparatus is input, the method of controlling the display apparatus transmits the voice's user to the interactive server, while determining whether the user's voice is a pre-stored command in the display apparatus, and in response to the user's voice not being a pre-stored command in the display apparatus and the control information which corresponds to the user's voice and first guide information guiding the pre-stored command capable of the same function as the user's voice are transmitted from the interactive server, the method performs the function of the display apparatus, according to the control information transmitted from the interactive server, and displays the first guide information. Electronic apparatuses that recognize voices spoken by users and perform functions corresponding thereto have been increasingly used. In general, a display apparatus capable of recognizing the voice collects the voice spoken by the user and transmits a spoken voice signal corresponding to the collected spoken voice to a server connected through a network. The server that receives the spoken voice signal analyzes the spoken voice signal to determine an intention of the user, and generates the resulting response signal and transmits the generated response signal to the display apparatus. As a result, the display apparatus can execute the function corresponding to the spoken voice of the user or provide information based on the response signal received from the server. However, the display apparatus capable of recognizing the voice in the related art has a limitation in analyzing the spoken voice of the user and determining the intention of the user based on a result of the analysis. For example, in the case of a simple function such as "channel-up", the server analyzes the spoken voice signal to correctly determine the intention of the user and generates the resulting response signal to transmit the generated signal to the display apparatus. Accordingly, the display apparatus can display a channel requested by the user based on the response signal. However, when the spoken voice is unclearly recognized or when user's interaction is required, providing the simple function in the related art is not sufficient. If the user speaks "Tell me a recording method.", there is a problem in that a matter to be checked or an operation of the user for recording cannot be instructed to the user for each step and only the recording method is just displayed. Further, when a spoken voice such as "The screen is abnormal" is recognized, hardware performance of the display apparatus is not checked and there may be no response to the spoken voice. That is, when an executable response signal is not generated from the spoken voice, there is a problem in that an incorrect operation is performed or there is no response. In addition, although accuracy of a response to a complicated spoken voice is improved by using the server, there is also a problem in that the response signal is generated without reflecting characteristics of respective display apparatuses. Exemplary embodiments overcome the above disadvantages and other disadvantages not described above. Also, the embodiments are not required to overcome the disadvantages described above, and an exemplary embodiment may not overcome any of the problems described above. The embodiments provide a voice recognition system, a server, a display apparatus, and control methods thereof which generate a response signal to a spoken voice of a user based on a prestored manual and process an operation corresponding thereto. According to an aspect, there is provided a system comprising a server and a display apparatus as set out in claim 1. Optional features are set out in claim 2. According to another aspect, there is provided a control method of a display apparatus as set out in claim 3. Optional features are set out in claim 4. Additional and/or other aspects and advantages of the embodiments will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the embodiments. The above and/or other aspects of the embodiments invention will be more apparent by describing certain exemplary embodiments with reference to the accompanying drawings, in which: FIG. 1 is a diagram illustrating a voice recognition system according to an exemplary embodiment;FIG. 2 is a block diagram illustrating a configuration of
