Audio Description Services for Sports Programs
Automatic generation of audio commentary of sports programs for the visually impaired

Outline

This is a service for live broadcasts where real-time data of each game (e.g.competitors’ names, start lists, official scores and so on) is used to automatically generate Japanese text that describes the progress of the game, which is read out using speech synthesis.

Features

Universal service
Although information that can be gathered by looking at the screen is often not actually described in TV audio, an automatic audio description can explain the progress of a game in great detail. By listening to both the TV audio and the automatic audio description, it is possible for people with visual impairment or anyone else who is unable to watch the video (car drivers, for example) to enjoy the program fully.
Services that supplement broadcast services with online streaming
An audio description can be added automatically to sports footage with no running commentary. Universal services that supplement broadcasting with online streaming are expected to offer various benefits such as allowing greater numbers of people to view unbroadcast sporting events.

Future plans

We are carrying out research aimed at synthesizing speech that is natural and easy to understand, and suitable Japanese expressions for use in automatic audio descriptions.

  • The research on speech synthesis technology is jointly being conducted with AI Inc.
