Abstract

The invention relates to a method for automatically overlapping subtitles to audio and video and a device for automatically overlapping subtitles to audio and video; the method includes steps of extracting audio data from an audio / video file; automatically recognizing the audio information and generating the subtitle file; delaying the audio / video file; compounding the audio / video file and the subtitle file to form the audio / video file with the subtitles. Through applying an independent device, the audio information in the audio / video file is separated and extracted, thus the independent device is applied to automatically identify the audio data and generate corresponding subtitle information; at last, the subtitle information and the strict time of the original audio / video file are in synchronization through a compounding device and overlapped to form the audio / video file with the subtitles; the method and device change the traditional subtitle adding method of artificial subtitle, effectively save time, and improve efficiency; meanwhile, the hardware device is accurately synchronous, and the synchronous effect of the subtitles and the audio / video image is greatly improved, and the enjoyment experience of improved.

Description

technical field [0001] The invention relates to a method and a device for automatically superimposing subtitles on audio and video, in particular to a method and a device for automatically superimposing subtitles on audio and video in the technical fields of video image processing and audio and video processing. Background technique [0002] With the development of society and the rapid interpenetration of regional culture, audio and video data information has always played an important media role as an intuitive information transmission mode. The emergence of subtitles is introduced to solve regional cultural and language differences. Adding subtitle information to audio and video information synchronously can not only effectively help people with hearing impairment and disabilities to grasp and understand the information that audio and video want to convey, It can also eliminate the ambiguity caused by homophones with the same pronunciation but completely different meaning...
