KYOTO -- Yuko Shiomi, a professional narrator with the radio station KBS Kyoto, speaks into a microphone. Her role is that of "Kakuunsai," a fictional character depicting a distinguished calligrapher.

In the recording booth on the other side of a glass window, sound composer Tomoyuki Hikasa checks the tone of her voice and speed of her narration.

There is nothing unusual about this recording scene, apart from the fact that it is a voluntary activity aimed at completing the creation of a CD-ROM that helps the visually impaired learn how to use computer keyboards.
