Abstract

The invention discloses a voice retrieval method. The voice is voice data separated from video and audio data. The method comprises the following steps of: presetting: presetting an XML object database of material files or program files, wherein the XML object comprises XML element data for describing audio data and corresponding text attributes; and acquiring a voice characteristic quantity and a time code of each voice data, and associating each text character and the characteristic quantity and the time code of the corresponding voice respectively; searching: searching the matched text information in the XML object database according to the searching keywords submitted by a user, and extracting the corresponding audio information according to the voice characteristic quantity and the time code associated with the text; and outputting: displaying the video and audio information and the text information on a search result interface. The method is convenient for the user to simply and quickly acquire the desired video and associated text information, and does not occupy excessive system resources.

Description

technical field [0001] The invention relates to the technical field of multimedia data processing, in particular to a voice retrieval method and a voice retrieval device. Background technique [0002] Due to the popularity of the Internet, a large amount of information is rapidly accumulated and widely used. Therefore, the distance in time and space is no longer the biggest obstacle for people to access and use information. Instead, the problem is the lack of efficient ways to find desired information in the vast Internet. [0003] Information retrieval technologies (information retrieval technologies) have received special attention in recent years because they can provide users with convenient ways to access and use desired information. Until now, most of the research on information retrieval has focused on text query commands (text queries) to retrieve text information, that is, to do text-to-text comparisons. At present, research and system development in this area have...
