Abstract

A method includes crawling and indexing voice sites and storing results in an index; receiving a search request in voice from a user via a telephone; performing speech recognition on the voice search request and converting the request from voice to text; parsing the query; and performing a search on the index and ranking the search results. Search results may be filtered based on attributes such as location and context. Filtered search results may be presented to the user in categories to enable easy voice browsing of the search results by the user. Computer program code and systems are also provided.
