Abstract

The invention discloses an automatic splitting method and an automatic splitting system for audio punctuation. The method comprises the following steps: acquiring multiple framed segments according to an audio; acquiring an energy threshold value according to energy values of each framed segment, acquiring the framed segment of which the energy value exceeds the energy threshold value Et from each framed segment according to the energy threshold value, scanning a previous frame or a subsequent frame of the frame by taking the framed segment as a sentence middle frame, and if the energy value of the previous frame or the subsequent frame is lower than the set energy threshold value Et, combining the frame and the sentence middle frame into an independent sentence according to a frame starting sequence, and performing spectral entropy analysis on each independent sentence to obtain final analyzed sentences. Therefore, the problem of incapability in automatic punctuation in an existing caption corresponding process is solved. Therefore, not only can recorded audios and videos be processed, but also live audios and videos can be processed. For a webcast stream, webcast voices can be automatically cut, so that convenience is brought to parallel processing of a subsequent link such as a dictation link, and the processing time is shortened.

Description

technical field [0001] The invention relates to the technical field of voice and subtitle processing, in particular to a method and system for automatically splitting audio sentences. Background technique [0002] At present, in the field of subtitle production, sentence segmentation is mainly performed manually. The premise of artificial voice segmentation is to listen to all the voices, and mark the start and end points of a sentence by tapping shortcut keys while dictating. Due to the delay of slapping, the obtained start point and end point are misaligned and need to be adjusted manually. The whole process takes a lot of time. For example, 30 minutes of audio requires 40 minutes to 1 hour of sentence segmentation time, which is extremely low in productivity. In the field of webcasting, if sentences are not segmented and dictation is performed manually, it is difficult to parallelize, and the speed of human dictation will be slower than the speed of live broadcasting.
