Abstract

A data processing apparatus includes a speech recognition unit configured to perform continuous speech recognition on speech data, a related word acquiring unit configured to acquire a word related to at least one word obtained through the continuous speech recognition as a related word that is related to content corresponding to content data including the speech data, and a speech retrieval unit configured to retrieve an utterance of the related word from the speech data so as to acquire the related word whose utterance has been retrieved as metadata for the content.

Claims

1. A data processing apparatus comprising:

speech recognition means for performing continuous speech recognition on speech data;

related word acquiring means for acquiring a word related to at least one word obtained through the continuous speech recognition, as a related word that is related to content corresponding to content data including the speech data; and

speech retrieval means for retrieving an utterance of the related word from the speech data so as to acquire the related word whose utterance has been retrieved as metadata for the content.

2. The data processing apparatus according to claim 1, further comprising topic estimating means for estimating a topic of substance of speech corresponding to the speech data, on the basis of a result of the continuous speech recognition, wherein

the related word acquiring means acquires a word related to the topic as the related word.

3. The data processing apparatus according to claim 2, wherein the related word acquiring means acquires, from among words related to the at least one word obtained through the continuous speech recognition, a word other than the words that should be recognized by the continuous speech recognition, as the related word.

4. The data processing apparatus according to claim 2, wherein the related word acquiring means acquires a new word appearing in a sentence of the topic, as the related word.

5. The data processing apparatus according to claim 2, wherein

the content data is assigned metadata for the content, and

the topic estimating means estimates the topic also on the basis of the metadata assigned to the content data.

6. The data processing apparatus according to claim 5, wherein

the content data is data of a program included in broadcast data in television broadcasting,

the broadcast data includes electronic program guide (EPG) data as the metadata for the program in addition to the data of the program, and

the topic estimating means estimates the topic also on the basis of the EPG data included in the broadcast data.

7. The data processing apparatus according to claim 5, wherein in the case where the metadata assigned to the content data includes a proper name, the related word acquiring means acquires, as the related word, also a proper name that is related to the proper name included in the metadata assigned to the content data.

8. The data processing apparatus according to claim 2, wherein the related word acquiring means acquires the related word from a server on a network.

9. The data processing apparatus according to claim 2, further comprising:

metadata storing means for storing the metadata for the content in association with the content data;

metadata retrieval means, when a keyword is input, for retrieving metadata matching or similar to the keyword from the metadata stored in the metadata storing means; and

content recommendation means for recommending content that corresponds to the content data associated with the metadata retrieved by the metadata retrieval means.

10. The data processing apparatus according to claim 9, further comprising reproduction control means, when content to be reproduced is designated from among the content recommended by the content recommendation means, for reproducing the designated content.

11. A data processing method comprising the steps of:

performing continuous speech recognition on speech data;

acquiring a word related to at least one word obtained through the continuous speech recognition as a related word that is related to content corresponding to content data including the speech data; and

retrieving an utterance of the related word from the speech data so as to acquire the related word whose utterance has been retrieved as metadata for the content;

the steps being performed by a data processing apparatus.

12. A program for causing a computer to function as:

speech recognition means for performing continuous speech recognition on speech data;

related word acquiring means for acquiring a word related to at least one word obtained through the continuous speech recognition as a related word that is related to content corresponding to content data including the speech data; and

speech retrieval means for retrieving an utterance of the related word from the speech data so as to acquire the related word whose utterance has been retrieved as metadata for the content.

13. A data processing apparatus comprising:

a speech recognition unit configured to perform continuous speech recognition on speech data;

a related word acquiring unit configured to acquire a word related to at least one word obtained through the continuous speech recognition as a related word that is related to content corresponding to content data including the speech data; and

a speech retrieval unit configured to retrieve an utterance of the related word from the speech data so as to acquire the related word whose utterance has been retrieved as metadata for the content.
