receiving a user voice according to the voice command guide; and performing a function corresponding to the user voice, wherein the current situation includes at least one of a first situation and a second situation, wherein the outputting a voice command guide comprises displaying a first voice command guide applicable to the first situation in the first situation and displaying a second voice command guide applicable to the second situation in the second situation, and wherein the first voice command guide and the second voice command guide are different from each other. ### Claim 2 (depends on 1) The method as claimed in claim 1, wherein at least one of the first situation and the second situation includes a situation of outputting an initial screen, a situation of outputting a content or a situation of executing an application. ### Claim 3 (depends on 2) The method as claimed in claim 2, wherein the first situation includes a situation of outputting a content which is received through a tuner, and the second situation includes a situation of executing an application related to an external apparatus. ### Claim 4 (depends on 1) The method as claimed in claim 1, wherein in response to the current situation being changed, the voice command guide is changed. ### Claim 5 (depends on 1) The method as claimed in claim 1, further comprising: in response to the user voice being input, transmitting the user voice to a server; and receiving response information corresponding to the user voice from the server, wherein the displaying a voice command guide comprises displaying the voice command guide which is applicable to the current situation based on the response information. ### Claim 6 (depends on 5) The method as claimed in claim 5, further comprising: in response to the response information corresponding to the user voice received through a voice collector being received, outputting a system response. ### Claim 7 (depends on 6) The method as claimed in claim 6, wherein the voice collector is built in the display apparatus or separated from the display apparatus, and wherein the displaying the voice command guide comprises, in response to a system response corresponding to the user voice being output, outputting a voice command guide related to the system response. ### Claim 8 (depends on 1) The method as claimed in claim 1, wherein the outputting the voice command guide comprises, in response to a content list which is searched according to a user voice for searching a content being output, displaying a voice command guide for filtering a content included in the content list. ### Claim 9 (depends on 1) The method as claimed in claim 1, wherein the outputting the voice command guide comprises, in response to a content list which is searched according to a user voice for searching a content being output, outputting at least one of a voice command guide for executing a specific content included in the content list and a voice command guide for outputting detailed information of the specific content. ### Claim 10 (depends on 1) The method as claimed in claim 1, wherein the outputting the voice command guide comprises, in response to a corresponding application execution screen being output according to a user command for executing an application, outputting a voice command guide which is applicable to the application execution screen. ### Claim 11 A display apparatus, comprising: an output unit; a storage configured to store a plurality of sample sentences corresponding to voice commands which are applicable to each display situation of the display apparatus; and a controller configured to display a voice command guide including a sample sentence corresponding to a voice command which is applicable to a current situation of the display apparatus from among the plurality of stored sample sentences through the output unit and perform a function corresponding to an input user voice according to the voice command guide, wherein the current situation includes at least one of a first situation and a second situation, wherein the controller displays a first voice command guide applicable to the first situation in the first situation and displays a second voice command guide applicable to the second situation in the second situation, and wherein the first voice command guide and the second voice command guide are different from each other. ### Claim 12 (depends on 11) The apparatus as claimed in claim 11, wherein at least one of the first situation and the second situation includes a situation of outputting an initial screen, a situation of outputting a content or a situation of executing an application. ### Claim 13 (depends on 12) The apparatus as claimed in claim 12, the first situation includes a situation of outputting a content which is received through a tuner, and the second situation includes a situation of executing an application related to an external apparatus. ### Claim 14 (depends on 11) The apparatus as claimed in claim 11, wherein in response to the current situation being changed, the voice command guide is changed. ### Claim 15 (depends on 11) The apparatus as claimed in claim 11, wherein the controller, in response to the user voice being input, transmits the user voice to a server, and in response to response information corresponding to the user voice being received, displays the voice command guide which is applicable to the current situation based on the response information. ### Claim 16 (depends on 15) The apparatus as claimed in claim 15, wherein the controller, in response to the response information corresponding to the user voice input through a voice collector being received, outputs a system response. ### Claim 17 (depends on 16) The apparatus as claimed in claim 16, wherein the voice collector is built in the display apparatus or separated from the display apparatus, and wherein the controller, in response to a system response corresponding to the user voice being output, outputs a voice command guide related to the system response. ### Claim 18 (depends on 11) The apparatus as claimed in claim 11, wherein the controller, in response to a content list which is searched according to a user command for searching a content being output, outputs a voice command guide for filtering a content included in the content list. ### Claim 19 (depends on 11) The apparatus as claimed in claim 11, wherein the controller, in response to a content list which is searched according to a user voice for searching a content being output, outputs at least one of a voice command guide for executing a specific content included in the content list and a voice command guide for outputting detailed information of the specific content. ### Claim 20 (depends on 11) The apparatus as claimed in claim 11, wherein the controller, in response to a corresponding application execution screen being output according to a user command for executing an application, outputs a voice command guide which is applicable to the application execution screen.
