Google's audio indexing service basically scans video content (from Youtube) for extracting audio data from it. Later, it applies a speech recognition algorithm for extracting words from obtained audio data and then index this textual data; GAUDI is not as interesting as it should be due to the spesific catalogue that it works on. For now, it's limited to election material of US presidency.
Another addition to Google Labs is "In Quotes" which's an application less ambitious than GAUDI. In Quotes can search words from newspapers and magazines and it is -again- limited to election material. Interested to find Sarah Palin's words on Turkey. Then visit In Quotes.
