  1. Now you can Search by the Words that are Spoken on YouTube Videos?

    YouTube has been promising for quite a while to make changes to the website to make it more accessible to the hearing impaired. It finally happened the other week, when Google lifted the curtains on a set of software technologies designed to independently provide captions for scenes on the videos on the website. The software at this point is only able to automatically put in captions for YouTube videos with speech in English. But users who do not speak English can use Google’s translation software to make out those captions in their own native language, in one of 51 choices. This way, it will not just be the hearing impaired who will benefit from this technology. A large number of YouTube viewers the world over who speak no English, would be able to make some sense of those videos, even if only minimally so.

    Even if the speech recognition method that Google uses is one that has been around for quite a while, in use in applications like voice-mail in a Google Voice, YouTube will be about the largest application that that speech recognition technology has ever seen. YouTube, Hulu and other sites that stream network programming have been including closed captioning from original network programming for quite long now. The new technology in use though will not look to the content provider to provide the captioning; it will just generate on its own, with speech recognition algorithms. Of course everyone knows that speech recognition is not a particularly well-developed technology. But often, it can help make a certain amount of sense of a situation, and that is better than having nothing at all.

    These days anyone who uploads a file on YouTube is given the option to attach a subtitle file of their own. The possibilities are endless; people can translate the subtitles automatically into their own language, and more importantly, people can use Google to search through words appearing in the subtitles, to locate a particular video or scene. Google provides software called Auto-timing that will help uploaders put up a proper subtitles file. Whichever way you see it, Google’s innovations usually come down to refining searchability; and a good plan that is too.
