Embodiment Construction

[0044] Specific embodiments of the present invention will be described in detail below.

[0045] Such as figure 1 As shown, the video editing method based on speech recognition for artificial intelligence education includes the following steps:

[0046] (1), input the teaching manuscript and convert it into a script file recognizable by the system, and then proceed to step (2);

[0047] (2), input the original teaching video material file, identify the audio frame contained in the original teaching video material file, identify the target audio frame whose voiceprint meets the preset condition, and enter step (3) after completion;

[0048](3), the video file after speech recognition is compared with the script file that step (1) obtains, determines the video clip that does not meet the teaching manuscript and includes the target audio, and enters step (4) after completion, wherein:

[0049] The video file after speech recognition contains target audio frames that meet preset...

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.

Description

technical field [0001] The invention relates to a video editing method and system, in particular to a speech recognition-based video editing method and system for artificial intelligence education. Background technique [0002] At present, with the development of science and technology, the change of educational concepts, the upgrading of user education needs and the change of lifestyle, the scale of artificial intelligence education continues to expand, and the artificial intelligence education model is more and more widely accepted by the society, especially in the field of primary and secondary education. Smart education can break through the limitations of time and space, provide more children with high-quality educational resources, and play an important role in making up for the uneven distribution of educational resources and improving educational equity. [0003] Among the various teaching modes of artificial intelligence education, the output of teaching content gen...
