Abstract

In an embodiment, a transcription support system includes: a first storage, a playback unit, a second storage, a text generating unit, an estimating unit, and a setting unit. The first storage stores the voice data therein; a playback unit plays back the voice data; and a second storage stores voice indices, each of which associates a character string obtained from a voice recognition process with voice positional information, for which the voice positional information is indicative of a temporal position in the voice data and corresponds to the character string. The text creating unit creates text; the estimating unit estimates already-transcribed voice positional information based on the voice indices; and the setting unit sets a playback starting position that indicates a position at which playback is started in the voice data based on the already-transcribed voice positional information.

Claims

1. A transcription support system comprising:

a first storage configured to store voice data therein;

a playback unit configured to play back the voice data;

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

a text creating unit that creates text in response to an operation input of a user;

an estimating unit configured to estimate already-transcribed voice positional information indicative of a temporal position at which the creation of the text is completed in the voice data based on the voice indices; and

a setting unit configured to set a playback starting position indicative of a position at which the playback is started in the voice data based on the already-transcribed voice positional information.

2. The system according to claim 1, further comprising

a playback controller configured to control the playback unit to play back from the playback starting position when the playback controller receives a playback instruction to play back the voice data.

3. The system according to claim 1, wherein the estimating unit

specifies a character string that matches with a character string constituting the text created by the text creating unit out of a plurality of character strings included in the voice indices, and

estimates the already-transcribed voice positional information from voice positional information corresponding to a character string matched with a last character string of the text out of the specified character strings.

4. The system according to claim 1, wherein

the setting unit sets a position indicated by the already-transcribed voice positional information as the playback starting position.

5. The system according to claim 1, wherein

the setting unit sets a position that is before a position indicated by the already-transcribed voice positional information as the playback starting position.

6. A transcription support system comprising:

a first storage configured to store voice data therein;

a playback unit configured to play back the voice data;

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

a text creating unit that creates text in response to an operation input of a user;

an estimating unit configured to estimate already-transcribed voice positional information that indicates a temporal position at which the creation of the text is completed in the voice data based on the voice indices;

an acquiring unit configured to acquire playback voice positional information that indicates a current position of the voice data that is being played back by the playback unit;

a calculator configured to calculate a delay amount based on the already-transcribed voice positional information and the playback voice positional information, wherein

the delay amount indicates how much the generation of the text is delayed compared to the playback of the voice data; and

a playback controller configured to variably control the playback of the playback unit so as for the delay amount to fall within a predetermined range.

7. The system according to claim 6, wherein

the playback controller controls the playback unit to temporarily stop the playback of the voice data at the current playback position when the delay amount is equal to or larger than a first threshold.

8. The system according to claim 6, wherein,

the playback controller, when the delay amount is equal to or larger than a first threshold, controls the playback unit

to issue a predetermined warning sound,

to return the playback position of the voice data to a position that the already-transcribed voice positional information indicates, and

to continue the playback.

9. The system according to claim 6, wherein

the playback controller, when the delay amount is equal to or larger than a second threshold, controls the playback unit to playback the voice data lower than a speed of a normal playback.

10. The system according to claim 6, wherein

the playback controller, when the delay amount is equal to or larger than a second threshold, controls the playback unit

to playback a voice portion that includes the voice in the voice data at maintained normal speed, and

to playback a silent portion that does not include a voice in the voice data lower speed than a speed in a normal playback.

11. A transcription support method comprising:

playing back voice data;

creating text in response to an operation input of a user;

estimating already-transcribed voice positional information indicative of a position at which the generation of the text is completed in the voice data based on voice indices each of which associates a character string obtained from a voice recognition process with voice positional information, the voice positional information indicative of a temporal position in the voice data and corresponding to the character string; and

setting a playback starting position that indicates a position at which playback is to start based on the already-transcribed voice positional information.
