Voice Interface for a Search Engine – Patent Won!
5 years ago, Google filed a patent for Voice Interface for a Search Engine and today they were granted the patent! According to the abstract at USPTO, the voice search engine is described as system which provides search results from a voice search query. The system receives a voice search query from a user, derives one or more recognition hypotheses, each being associated with a weight, from the voice search query, and constructs a weighted boolean query using the recognition hypotheses. The system then provides the weighted boolean query to a search system and provides the results of the search system to a user.
In November last year, I had put together a guide of google services at the time in blog-fashion and had listed the Google Voice Search (GVS) which was an early candidate of Google Labs. Since the patent was filed in Feb 2001, the Google Voice Search was tested in 2002 as a demo, but soon afterwards the service was discontinued for unknown reasons. Google's Research Publications, which details papers written by Googlers, lists a paper in PDF format by Alex Franz and Brian Milch (CS Department at University of Californmia, Berkley) titled: Searching the Web by Voice.
When GVS was an active demo, it used to work by following the steps below:
1. Pick up the phone and call the automated voice search system at (650) 623-6706.
2. After the prompt Say your Search Keywords, say your query to the system.
3. Click this link and a new window will open with your voice search results.
4. Say another query, and the new window with the search results will be updated with the new results.
It just might be the right time that GVS is coming out, given that we have Google Mobile Ads now along with Click2Call, plus all the other offerings by Google at <a href="http://mobile.google.com">GMobile</a>
