Abstract

A display apparatus includes an input unit configured to receive a user command; an output unit configured to output a registration suitability determination result for the user command; and a processor configured to generate phonetic symbols for the user command, analyze the generated phonetic symbols to determine registration suitability for the user command, and control the output unit to output the registration suitability determination result for the user command. Therefore, the display apparatus may register a user command which is resistant to misrecognition and guarantees high recognition rate among user commands defined by a user.

Claims

1. A display apparatus comprising:

an input unit configured to receive a user command;

an output unit configured to output a registration suitability determination for the user command; and

a processor configured to generate phonetic symbols for the user command, analyze the generated phonetic symbols to determine the registration suitability for the user command, and control the output unit to output the registration suitability determination for the user command.

2. The display apparatus as claimed in claim 1, wherein the processor analyzes at least one of a number of the generated phonetic symbols and a successive configuration of vowels and consonants in the generated phonetic symbols to determine the registration suitability for the user command.

3. The display apparatus as claimed in claim 2, wherein the processor further analyzes at least one of a configuration form of the generated phonetic symbols, a number of generated phonetic symbols for each word, and whether or not the generated phonetic symbols include weak phonetic symbols to determine the registration suitability for the user command,

wherein the weak phonetic symbols include phonetic symbols for a specific pronunciation of which a frequency band or energy magnitude is decreased or lost by a surrounding environment, such that a recognition rate thereof is degraded.

4. The display apparatus as claimed in claim 2, wherein the output unit displays a user interface (UI) guiding a registrable user command in response to the registration suitability for the user command being determined to not be suitable, and outputs an audio for the user command in response the registration suitability for the user command being determined to be suitable.

5. The display apparatus as claimed in claim 4, further comprising a storage unit,

wherein the processor registers and stores the user command in the storage unit according to a similarity between a text for the user command and a text for a spoken voice in response to the spoken voice for the user command being input in a state in which the audio for the user command is output.

6. The display apparatus as claimed in claim 2, wherein the processor determines the registration suitability for the user command, and registers and stores the user command in the storage unit according to a selection command of the user in a case in which the registration suitability for the user command does not belong to both of a suitable case and an unsuitable case.

7. The display apparatus as claimed in claim 1, wherein the processor measures a similarity between phonetic symbols for a plurality of pre-registered commands and phonetic symbols of the user command to determine the registration suitability for the user command according to the measured similarity.

8. The display apparatus as claimed in claim 1, wherein the processor determines the registration suitability for the user command according to whether or not the user command corresponds to a prohibited command.

9. The display apparatus as claimed in claim 1, wherein the input unit receives one or more texts for a spoken voice from a voice recognition apparatus in response to the spoken voice for the user command being input, and

the processor determines a text selected by a user among one or more input texts as a text for the user command.

10. The display apparatus as claimed in claim 1, wherein the user command includes at least one of a trigger command for entering a voice recognition mode and a control command for controlling an operation of the display apparatus.

11. A method for registration of a user command, the method comprising:

receiving the user command;

generating phonetic symbols for the user command based on a predefined phonetic symbol set;

determining a registration suitability for the user command by analyzing the generated phonetic symbols; and

providing the registration suitability determination for the user command.

12. The method as claimed in claim 11, wherein the determining of the registration suitability includes analyzing at least one of a total number of the generated phonetic symbols and a successive configuration of vowels and consonants in the generated phonetic symbols.

13. The method as claimed in claim 12, wherein the determining of the registration suitability further includes analyzing at least one of a configuration form of the generated phonetic symbols, the number of generated phonetic symbols for each word, and whether or not the generated phonetic symbols include weak phonetic symbols, and

the weak phonetic symbols include phonetic symbols for a specific pronunciation of which a frequency band or energy magnitude is decreased or lost by a surrounding environment, such that a recognition rate thereof is degraded.

14. The method as claimed in claim 12, wherein the providing of the registration suitability determination for the user command includes providing a guide user interface (UI) guiding a registrable user command in response to the registration suitability for the user command being determined to not be suitable, and an audio for the user command is output in response to the registration suitability for the user command being determined to be suitable.

15. The method as claimed in claim 14, further comprising registering the user command according to a similarity between a text for the user command and a text for a spoken voice in response to the spoken voice for the user command being input in a state in which the audio for the user command is output.

16. The method as claimed in claim 15, wherein in the registering of the user command, the registration suitability for the user command is determined, and the user command is registered according to a selection command of the user in a case in which the registration for the user command does not belong to both of a suitable case and an unsuitable case.

17. The method as claimed in claim 11, wherein in the determining of registration suitability for the user command, the registration suitability for the user command is determined according to a similarity between generated phonetic symbols for a plurality of pre-registered commands and generated phonetic symbols of the user command.

18. The method as claimed in claim 11, wherein in the determining of registration suitability for the user command, the registration suitability for the user command is determined according to whether or not the user command corresponds to a prohibited command.

19. The method as claimed in claim 11, wherein in the receiving of the user command, in response to a spoken voice for the user command being input, one or more texts for the spoken voice is received from a voice recognition apparatus, and

a text selected by a user among one or more input texts is determined as a text for the user command.

20. The method as claimed in claim 11, wherein the user command includes at least one of a trigger command for entering a voice recognition mode and a control command for controlling an operation of the display apparatus.

21. A computer program stored in a non-transitory recording medium coupled to a display apparatus to execute operations of:

receiving a user command;

generating phonetic symbols for the user command based on a predefined phonetic symbol set;

determining a registration suitability for the user command by analyzing the generated phonetic symbols; and

providing the registration suitability determination for the user command,

wherein the computer program registers the user command.
