Abstract

The invention discloses a keyword-based timestamp positioning and searching method in audio and video. The method comprises the following steps: S1, preparing audio and video; S2, performing characterrecognition on audio parts in the audio and the video through a third-party voice recognition technology to generate an LRC file which comprises a character timestamp; S3, carrying out word segmentation processing on the characters of the LRC file content and storing the characters into an ElasticSearch search engine; and S4, searching the keyword inputted by the user and returning a timestamp when the keyword appears. The keywords of the character parts in the audio and video files are marked, and the user can quickly find the positions of the keywords appearing in the audio and video filesaccording to the timestamps in a timestamp marking manner so that the method is convenient and efficient to use.
