Abstract

The invention discloses a video editing method for artificial intelligence education based on speech recognition. The method comprises the following steps: (1) inputting a teaching document and converting the teaching document into a script file which can be recognized by a system; (2) inputting an original teaching video material file, identifying an audio frame contained in the original teachingvideo material file, and identifying a target audio frame of which the voiceprint satisfies a preset condition; (3) comparing the video file subjected to voice recognition with a script file, and determining a video clip which does not conform to the teaching document and contains a target audio; (4) finding out and automatically deleting video clips which do not conform to the teaching documentin the video file subjected to voice recognition; (5) automatically rendering video clips including audio conforming to the teaching document, and synthesizing the video clips into a complete video; and (6) outputting the synthesized complete video. The invention also discloses a video editing system for artificial intelligence education based on speech recognition.
