Another Google innovation: an audio index called Gaudi. Currently, it only pulls information from YouTube videos, but it’s a start. Personally, I don’t think it will be too long before other kinds of videos are covered. Also, though the main page implies that it covers only politicians’ speeches, this isn’t the case – it covers all YouTube videos. As they have admitted, part of the logic was to encourage and celebrate democracy in this year of the US general elections – Gaudi could be thought of as a mechanism to assist voters in gathering all relevant information about candidates. If you have more questions about the whole thing (I did), take a look at the FAQ.
