在线教学平台中视频语音识别系统设计

Abstract

Abstract:

On the online collaborative learning platform,speech recognition of videos is crucial to facilitate users in faster searching and choosing multimedia files in a network and completed the information retrieval operation in teaching videos.The teaching video speech recognition system in the paper,which is an application case of hidden Markov model in extracting texts from audio or video teaching files,has important application value.This paper makes a requirement analysis of applied software for speech recognition,and tests the performance of some related functions.The results show that the designed system can realize and display the conversion of audio information in video into texts.

Key words: online learning;speech recognition;system design
