Abstract

A speech search method performed by a display device, the method including outputting media data including audio data, receiving a speech search command for additional data about the outputted media data from a user, the speech search command including at least one query word, determining whether the at least one query word matches a query term that is full and searchable, when the at least one query word matches the query term that is full and searchable, performing a search for the additional data using the query term, and when the at least one query word does not match the query term that is full and searchable, determining the query term from a predetermined amount of the audio data prior to receiving the speech search command and performing the search for the additional data using the query term.

Claims

1. A speech search method performed by a display device, the method comprising:

outputting media data including audio data;

receiving a speech search command for additional data about the outputted media data from a user, the speech search command including at least one query word;

determining whether the at least one query word matches a query term that is full and searchable;

when the at least one query word matches the query term that is full and searchable, performing a search for the additional data using the query term; and

when the at least one query word does not match the query term that is full and searchable, determining the query term from a predetermined amount of the audio data prior to receiving the speech search command and performing the search for the additional data using the query term.

2. The method of claim 1, wherein the step of determining whether the at least one query word matches a query term that is full and searchable comprises:

determining whether the at least one query word matches the query term based on at least one of pronunciation patterns of the user and context information of the media data.

3. The method of claim 2, wherein the context information comprises at least one of title information, genre information, character information, scene information, schedule information, audio related information, and image related information of the media data.

4. The method of claim 1, wherein the step of determining the query term from the predetermined amount of the audio data comprises:

voice-recognizing the predetermined amount of the audio data;

extracting at least one query term candidate from a corresponding voice recognition result; and

determining the at least one query word that matches the query term that is full and searchable from the at least one query term candidate.

5. The method of claim 4, the method further comprising:

outputting the at least one query term candidate when the at least one query term candidate does not match the at least one query word.

6. The method of claim 1, wherein the step of determining the query term from the predetermined amount of the audio data comprises:

voice-recognizing the predetermined amount of the audio data;

extracting at least one query term candidate from a corresponding voice recognition result;

outputting the at least one query term candidate; and

receiving a command for selecting the query term from the at least one query term candidate.

7. The method of claim 6, wherein the outputting step of the at least one query term candidate comprises

providing the user with the at least one query term candidate in a chronological order;

and

providing the user with an image of the media data while the at least one query term candidate being outputted.

8. The method of claim 1, wherein the step of performing the search further comprises:

providing the user with a confirmation request for the determined query term; and

when the determined query term is confirmed by the user, performing the search using the confirmed query term.

9. The method of claim 1, wherein the step of determining whether the at least one query word matches the query term that is full and searchable further comprises:

determining whether the at least one query word corresponds to the full and searchable query term or a partial query term.

10. A display device, comprising:

a media data processing module configured to process media data;

a media data output unit configured to output the processed media data;

an audio input unit configured to receive a speech search command for additional data about the outputted media data from a user, the speech search command including at least one query word; and

a processor configured to

determine whether the at least one query word matches a query term that is full and searchable,

when the at least one query word matches a query term in that is full and searchable, perform a search for the additional data using the query term, and

when the at least one query word does not match the query term that is full and searchable, determine the query term from a predetermined amount of the audio data prior to receiving the speech search command and perform the search for the additional data using the query term.

11. The display device of claim 10, wherein the processor is further configured to

determine whether the at least one query word matches the query term based on at least one of pronunciation patterns of the user and context information of the media data.

12. The display device of claim 11, wherein the context information comprises at least one of title information, genre information, character information, scene information, schedule information, audio related information, and image related information of the media data.

13. The display device of claim 10, wherein the processor is further configured to

voice-recognize the predetermined amount of the audio data;

extract at least one query term candidate from a corresponding voice recognition result; and

determine the at least one query word that matches the query term that is full and searchable from the at least one query term candidate.

14. The display device of claim 13, wherein the processor is further configured to

output the at least one query term candidate when the at least one query term candidate does not match the at least one query word.

15. The display device of claim 10, wherein the processor is further configured to

voice-recognize the predetermined amount of the audio data;

extract at least one query term candidate from a corresponding voice recognition result;

output the at least one query term candidate; and

receive a command for selecting the query term from the at least one query term candidate.

16. The display device of claim 15, wherein the processor is further configured to

provide the user with the at least one query term candidate in a chronological order;

and

provide the user with an image of the media data while the at least one query term candidate being outputted.

17. The display device of claim 10, wherein the processor is further configured to

provide the user with a confirmation request for the determined query term;

and

when the determined query term is confirmed by the user, perform the search using the confirmed query term.

18. The display device of claim 10, wherein the processor is further configured to

determine whether at least one query word corresponds to a full and searchable query term or a partial query term.
