Abstract

According to an embodiment, an information processing apparatus includes a storage unit, a detector, an acquisition unit, and a search unit. The storage unit configured to store therein voice indices, each of which associates a character string included in voice text data obtained from a voice recognition process with voice positional information, the voice positional information indicating a temporal position in the voice data and corresponding to the character string. The acquisition unit acquires reading information being at least a part of a character string representing a reading of a phrase to be transcribed from the voice data played back. The search unit specifies, as search targets, character strings whose associated voice positional information is included in the played-back section information among the character strings included in the voice indices, and retrieves a character string including the reading represented by the reading information from among the specified character strings.

Claims

1. An information processing apparatus comprising:

a storage unit configured to store therein voice indices, each of which associates a character string included in voice text data obtained from a voice recognition process with voice positional information, the voice positional information indicating a temporal position in the voice data and corresponding to the character string;

a detector configured to detect playback section information indicating a section that has been played back in the voice data;

an acquisition unit configured to acquire reading information that is at least a part of a character string representing a reading of a phrase to be transcribed from the voice data that has been played back; and

a search unit configured to specify, as search targets, character strings whose associated voice positional information is included in the played-back section information among the character strings included in the voice indices, and retrieve a character string including the reading represented by the reading information from among the specified character strings.

2. The apparatus according to claim 1, wherein the voice text data has a lattice structure.

3. The apparatus according to claim 1, further comprising a dictionary storage unit configured to store therein a dictionary in which a plurality of character strings is preregistered, wherein

the search unit retrieves a character string including the reading represented by the reading information from among the character strings registered in the dictionary storage unit.

4. The apparatus according to claim 1, further comprising a display unit configured to display the character string retrieved by the search unit.

5. The apparatus according to claim 1, further comprising a playback unit configured to play back the voice data.

6. An information processing method comprising:

detecting played-back section information indicating a section that has been played back in voice data;

acquiring reading information that is at least a part of a character string representing a reading of a phrase, to be transcribed from the voice data that has been played back;

specifying, among character strings included in voice indices, each of which associates a character string included in voice text data obtained from a voice recognition process with voice positional information, the voice positional information indicating a temporal position in the voice data and corresponding to the character string, character strings whose associated voice positional information is included in the played-back section information as search targets; and

retrieving a character string including the reading represented by the reading information from among the specified character strings.

7. A computer program product comprising a computer-readable medium including programmed instructions, wherein the instructions, when executed by a computer, cause the computer to execute:

detecting playback section information indicating a section that has been played back in voice data;

acquiring reading information that is at least a part of a character string representing a reading of a phrase to be transcribed from the voice data that has been played back;

specifying, among character strings included in voice indices, each of which associates a character string included in voice text data obtained from a voice recognition process with voice positional information, the voice positional information indicating a temporal position in the voice data and corresponding to the character string, character strings whose associated voice positional information is included in the playback section information as search targets; and

retrieving a character string including the reading represented by the reading information from among the specified character strings.
