The leading Internet search engine ÂGoogleÂ has been granted a patent for a system which provides search results from the query. The application has taken 5 years to be granted before the United States Patent and Trade Marks Office (ÂUSPTOÂ).
Â The inventors listed for the invention include co-founder of Google Sergey Brin, Alex Franz and the author of the paper entitled Searching the Web by Voice (2002) Brian Milch.
Â The patent application follows the outlay of the paper written in 2002. The paper identified a variety of problems with using speech as a tool for searching the Internet. The paper points out that most Internet queries are 5-6 words long and therefore a large vocabulary is required. The paper suggests that 100,000 words would only cover 80% of the traffic.
The abstract of the patent, which is entitled Voice interface for a search engine states that the invention is:
“A system 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.”
