Abstract

Provided is a conference system including: a first conversion unit configured to, during an online conference in which an occupant of a vehicle participates, convert a spoken voice in the online conference into text; a second conversion unit configured to convert the spoken voice into text with higher accuracy compared to the first conversion unit after an end of the online conference; a recording unit configured to record a video of the online conference and record the spoken voice; a playback unit configured to play back the video of the online conference recorded by the recording unit and the spoken voice recorded by the recording unit; and a text display unit configured to display text converted by the first conversion unit or text converted by the second conversion unit, accompanying the playback of the playback unit.

Claims (35)

1 . A conference system comprising a processor that functions as:

a first conversion unit configured to, during an online conference in which an occupant of a vehicle participates, convert a spoken voice in the online conference into text;

a second conversion unit configured to convert the spoken voice into text with higher accuracy compared to the first conversion unit after an end of the online conference;

a recording unit configured to record a video of the online conference and record the spoken voice;

a playback unit configured to play back the video of the online conference recorded by the recording unit and the spoken voice recorded by the recording unit; and

a text display unit configured to display text converted by the first conversion unit or text converted by the second conversion unit, accompanying the playback of the playback unit, wherein

the playback unit performs playback using a playback instrument in the vehicle, and

the text display unit displays text converted by the first conversion unit or text converted by the second conversion unit using a display unit in the vehicle, depending on a state of the vehicle.

2 . The conference system according to claim 1 , wherein

the text display unit displays text converted by the second conversion unit when the vehicle is in a driving state.

3 . The conference system according to claim 1 , wherein

when execution of a driving support function of the vehicle is turned on, or execution of an autonomous driving function of the vehicle is turned on,

the text display unit is configured to:

accept a selection operation as to whether text to be displayed accompanying the playback of the playback unit is text converted by the first conversion unit or text converted by the second conversion unit; and

display text selected by the selection operation using the display in the vehicle, accompanying the playback of the playback unit.

4 . The conference system according to claim 1 , wherein

the text display unit displays text converted by the second conversion unit using the display in the vehicle when a speed of the vehicle exceeds a predetermined value.

5 . The conference system according to claim 4 , wherein

the text display unit displays text converted by the first conversion unit when the speed of the vehicle is the predetermined value or smaller.

6 . An information processing device comprising a processor that functions as:

a first conversion unit configured to, during an online conference in which an occupant of a vehicle participates, convert a spoken voice in the online conference into text;

a second conversion unit configured to convert the spoken voice into text with higher accuracy compared to the first conversion unit after an end of the online conference;

a recording unit configured to record a video of the online conference and record the spoken voice;

a playback unit configured to play back the video of the online conference recorded by the recording unit and the spoken voice recorded by the recording unit; and

a text display unit configured to display text converted by the first conversion unit or text converted by the second conversion unit, accompanying the playback of the playback unit, wherein

the playback unit performs playback using a playback instrument in the vehicle, and

the text display unit displays text converted by the first conversion unit or text converted by the second conversion unit using a display in the vehicle, depending on a state of the vehicle.

7 . A non-transitory computer readable recording medium recording a program causing a processor of an information processing device to function as:

a first conversion unit configured to, during an online conference in which an occupant of a vehicle participates, convert a spoken voice in the online conference into text;

a second conversion unit configured to convert the spoken voice into text with higher accuracy compared to the first conversion unit after an end of the online conference;

a recording unit configured to record a video of the online conference and record the spoken voice;

a playback unit configured to play back the video of the online conference recorded by the recording unit and the spoken voice recorded by the recording unit; and

a text display unit configured to display text converted by the first conversion unit or text converted by the second conversion unit, accompanying the playback of the playback unit, wherein

the playback unit performs playback using a playback instrument in the vehicle, and

the text display unit displays text converted by the first conversion unit or text converted by the second conversion unit using a display in the vehicle, depending on a state of the vehicle.
