YouTube Captioning Expands

YouTube is expanding its automatic captioning. Google has added captioning to Japanese videos. It's the first language to be offered besides English, a service that rolled out in March. It's still a work in progress, so the service has glitches, but Google hopes it will give viewers some idea about what a video is about, if the video owner hasn't provided captioning themselves. This also makes videos searchable, based on audio content.
