Retrieval system and method for accurate positioning of audio/video speech information

Abstract

The present invention belongs to the field of audio / video speech information retrieval, and specifically relates to a retrieval system for accurate positioning of audio / video speech information. A retrieval system for accurate positioning of audio / video speech information is provided. The retrieval system comprises: a processing unit, a display unit and a manual operating unit. The display unit and the manual operating unit are both connected to the processing unit. The processing unit comprises a target file browsing module, a target file retrieval module, a searching module and a processing module. The target file browsing module, the target file retrieval module and the searching module are all connected to the processing module. All target files containing a same content can be retrieved from different hard disks and different folders, and reproduction of speeches and images synchronous to a retrieved content can be realized. The beneficial effects of the retrieval system and method for accurate positioning of audio / video speech information are that: audio / video speech information can be precisely positioned and rapidly retrieved according to free words, phrases, and fields of a target file, thereby providing a new method for the retrieval of audio / video files.

Description

technical field [0001] The invention belongs to the field of audio-video voice information retrieval, in particular to a retrieval system and method for precise positioning of audio-video voice information. Background technique [0002] With the rapid development of network and multimedia technology, the number of audio and video media is growing explosively, and people's demand for the retrieval and precise positioning of digital audio, video and voice information is becoming more and more prominent. In recent years, many new research and development directions have appeared in content-based audio and video retrieval. [0003] In traditional technology, most audio-video voice information retrieval systems and retrieval methods generally only perform keyword retrieval for voice information in audio files (for example: "Search method, device and equipment for voice information in audio files" patent application publication number: CN101996195A), instead of comprehensive retr...

AI Technical Summary

Problems solved by technology

For ordinary people, basically relying on personal experience, they can only rely on playing audio and video files for original manual search, which is time-consuming and laborious

It is far from meeting the information society's requirements for information timeliness and information standardized management
