Abstract

The embodiment of the invention discloses a method and system for dividing sentences in audio and an automatic caption generation method and system for video files. The method for dividing sentences in audio includes the steps of identifying first pause, identifying a first sentence, identifying second pause, determining whether the audio is finished, and if not, repeating the above sentence/pause identification step until the audio is finished, wherein the pause has a minimal length restriction, the sentence has a minimal length restriction and a maximal length restriction. The speech recognition rate is thus increased, which makes full automatic caption production possible.
