Electronic device and control method therefor

1. An electronic device comprising:

a voice inputter;

a storage configured to store a first text according to a first transcription format and at least one second text obtained by transcribing the first text in a second transcription format; and

a processor configured to, based on a voice text converted from a user voice input through the voice inputter corresponding to a preset instruction, execute a function according to the preset instruction,

wherein the processor is configured to execute a function according to the preset instruction, based on the preset instruction including the first text, and the voice text being a text in which the first text of the preset instruction has been transcribed into a second text in the second transcription format, wherein

the first text includes at least one of a letter, a number and a symbol transcribed in the first transcription format, and

the second text includes at least one text transcribed in the second transcription format, a pronunciation of the at least one text is the same as a pronunciation of the at least one of the letter, the number and the symbol.

2. The electronic device of claim 1 , wherein:

the voice text is divided in a preset text unit, and

the processor is configured to:

based on at least one of a text unit of the voice text including the second text, identify a first text corresponding to each of the second text, from the storage, and execute a function corresponding to an instruction identified based on the identified first text and the second text.

3. The electronic device of claim 2 , wherein the processor is configured to:

calculate a first similarity score of the preset instruction and the user voice based on a text unit of the voice text and whether any one of the identified first texts is included in the preset instruction, and based on the calculated first similarity score being greater than or equal to a preset threshold value, execute a function according to the preset instruction.

4. The electronic device of claim 3 , wherein:

the preset instruction is divided in a preset text unit,

the processor is configured to:

based on whether each of a text unit of the preset instruction being included in the text unit of the voice text and any one of the identified first text, further calculate a second similarity score of the preset instruction and the user voice, and based on each of the calculated first and second similarity scores being greater than or equal to a preset threshold value, execute a function according to the preset instruction.

5. The electronic device of claim 1 , further comprising:

a display,

wherein the preset instruction is displayed on a user interface (UI) provided through the display.

6. The electronic device of claim 5 , wherein the processor is configured to control the display to display a screen on which a function according to the preset instruction is executed.

7. The electronic device of claim 1 , further comprising:

a communicator,

wherein the processor is configured to control the communicator to transmit an image providing a screen on which the function according to the preset instruction is executed to a display device connected to the electronic device.

8. The electronic device of claim 1 , wherein the voice inputter comprises a microphone.

9. The electronic device of claim 1 , further comprising:

a communicator,

wherein the processor is configured to control the communicator to transmit the user voice input through the voice inputter to an external device and receive, from the external device, a voice text converted from the user voice according to voice recognition.

10. A control method of an electronic device storing a first text according to a first transcription format and at least one second text obtained by transcribing the first text in a second transcription format, the method comprising:

receiving a user voice; and

based on a voice text converted from the input user voice corresponding to a preset instruction, executing a function according to the preset instruction,

wherein the executing comprises executing a function according to the preset instruction, based on the preset instruction including the first text, and the voice text being a text in which the first text of the preset instruction has been transcribed into the second text in the second transcription format,

wherein the first text includes at least one of a letter, a number and a symbol transcribed in the first transcription format, and

wherein the second text includes at least one text transcribed in the second transcription format, a pronunciation of the at least one text is the same as a pronunciation of the at least one of the letter, the number and the symbol.

11. The method of claim 10 , wherein:

the voice text is divided in a preset text unit, and

the executing comprises, based on at least one of a text unit of the voice text including the second text, identifying a first text corresponding to each of the second text, from the storage, and executing a function corresponding to an instruction identified based on the identified first text and the second text.

12. The method of claim 11 , wherein the executing comprises:

calculating a first similarity score of the preset instruction and the user voice based on the text unit of the voice text and whether any of the identified first texts is included in the preset instruction; and

based on the calculated first similarity score being greater than or equal to a preset threshold value, executing a function according to the preset instruction.

13. The method of claim 12 , wherein the preset instruction is divided in a preset text unit,

wherein the method comprises, based on whether each of a text unit of the preset instruction being included in the text unit of the voice text and any one of the identified first text, calculating a second similarity score of the preset instruction and the user voice,

wherein the executing comprises, based on each of the calculated first and second similarity scores being greater than or equal to a preset threshold value, executing a function according to the preset instruction.

14. The method of claim 10 , further comprising:

displaying a user interface (UI) including the preset instruction; and

displaying a screen on which a function according to the pest instruction is executed.
