Abstract

The present invention is applicable to the field of computer technology, and provides a method and system for generating audio and video subtitles. The method includes: acquiring audio and video data, and extracting audio data in the audio and video data; Segment the audio data to obtain audio data segments that conform to the speaking style and the size of the video screen, and record the time information of the audio data segment; obtain the corresponding text data segment through voice recognition, and according to the audio data segment The time information is used to obtain the start time and end time of the corresponding text data segment to form subtitle text. The invention gets rid of the complicated workload of manually entering subtitles, realizes obtaining text data by identifying audio data, and generates complete subtitles simply and efficiently.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method and system for generating audio and video subtitles. Background technique [0002] With the continuous development of Internet technology, audio and video has attracted a large number of users with its convenient access experience, diverse video sources and real-time update speed, making audio and video an indispensable part of users' lives. The emergence of subtitles makes audio and video help people understand the content of audio and video in a more intuitive and reliable way. More and more users are used to audio and video files with subtitles. A segment of voice data and a large segment of text data are used to generate subtitles. For audio and video without subtitles, users can only rely on what they hear to understand, and the user experience is poor. [0003] Under the condition of no text manuscript, the existing method of generating audio and vid...
