Abstract

The embodiment of the invention discloses a video voice conversion method, a video voice conversion device and a server, and relates to the technical field of multimedia processing. The video voice conversion method, the video voice conversion device and the server are used for reducing the translation cost of voice in the video, and improving translation efficiency and translation accuracy. According to the method, the voice signal of a source language in the video is extracted, the voice signal of the source language is segmented, and sub voice signals of at least one section of source language are obtained; for the sub voice signals of each segment of source language, the sub voice signals of the source voice are converted into sub voice signals of a target language according to a pre-built voice model; the obtained sub voice signals of each segment of target language are merged with the video to obtain a video including the voice signals of the target language. When the video voice conversion method, the video voice conversion device and the server provided by the invention are adopted, the voice translation cost in the video can be reduced, and the translation efficiency and the translation accuracy can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of multimedia processing, and in particular, to a video-to-voice conversion method, device and server. Background technique [0002] Many times in life, you will come into contact with foreign language videos, such as Hollywood movies, foreign language learning tutorial videos, etc. For people who are not good at foreign languages, they need some auxiliary translation subtitles when watching these videos, but many foreign language videos There are no subtitles. If the viewer cannot understand the foreign language, the foreign language video at this time is meaningless to the viewer. [0003] In the prior art, in order to enable people to understand foreign language videos, the following three methods are mainly adopted: one is to add subtitles obtained by human translation in advance in the foreign language videos; the other is to make foreign language videos into dubbed films , th...
