ABSTRACT:
A search algorithm utilizing confidence levels of keywords spoken by a caller to identify keyword indexed search items which best match the spoken keywords. In response to receiving a spoken search request from a caller, keywords are identified in the spoken search request. A list of candidates is created comprising a match to at least one of the keywords, wherein each candidate in the list is assigned a level of confidence in the match. Keyword indexed search items having at least one of the keywords as an index and an original matching score are then located. The original matching score of each keyword indexed search item is weighted with the level of confidence in the list of candidates to form weighted matching scores. The keyword indexed search items are sorted based on weighted matching score. A list of the sorted keyword indexed search items is then created.
