  • Patent number: 7680853
    Abstract: Search results are provided in a format that allows users to efficiently determine whether audio or video documents identified from a search query actually contain the words in the query. This is achieved by returning snippets of text around query term matches and allowing the user to play a segment of the audio signal by selecting a word in the snippet. In other embodiments, markers are placed on a timeline that represents the duration of the audio signal. Each marker represents a query term match and when selected causes the audio signal to begin to play near the temporal location represented by the marker.
