Abstract

The invention discloses a method and a system for searching a digital archive library of an optical disc by voice, and relates to the field of voice recognition, including: establishing an archive package set of digital archives; establishing a semantic instruction set according to voice commands for searching digital archives; voice commands and digital archives There is a corresponding relationship; the archive package set is encoded to obtain the archive features; the semantic instruction set is encoded to obtain the search features; the mapping relationship between the archive features and the search features is determined; according to the mapping relationship, the voice command is used to search for digital archives. The present invention constructs a file encoder and a search encoder, and forms representations of different classes of the two encoders, calculates different losses in the correlation and irrelevance spaces, and finally forms an accurate match between the search encoder and the file encoder. Pair mapping relationship. Through the mapping relationship, the precise search of the data files of the optical disc library can be realized directly by voice.

Description

technical field [0001] The invention relates to the field of speech recognition, in particular to a method and a system for searching an optical disc digital archive by speech. Background technique [0002] The industry searches the database through text, and searches through keywords to match the meta information entered in the digital archives when they are stored. This search method depends entirely on the amount and type of meta-information manually entered in the archive digitization process. Since this search method can only hit meta information and cannot be understood from the semantics of each level of the archive data itself, this method limits the search results. [0003] In the process of file digitization, how to find files accurately, efficiently and conveniently has always been an urgent problem to be solved by file storage and administrators. Voice is the most convenient and efficient way of human-computer interaction. It can directly realize accurate searc...
