Google patents voice-activated searching

Now this is cool. According to, Google has just filed a patent on a voice interface for search engines. Through the use of a language model, phonetic dictionary and acoustic models, a server generates an n-best hypothesis list or word graph.

Though the patent application was in 2001, it was just published this week. Google Voice, which has been up for some time (it is currently down), allows the user to call into Google and tell them your search over the phone. It will then display the results in a new window.

This would be a terrific cell-phone searcher.
