Lecture voice file text conversion system based on lecture-related keywords

摘要

The present invention relates to a voice lecture file text-conversion system based on a lecture-based keyword. More specifically, the voice lecture file text-conversion system includes a lecture keyword input module such that a weight is applied to each keyword and search is performed through a search module based on the applied weight. Accordingly, lecture voice is converted into text based on text of a webpage formed with terminologies frequently used in a lecture and thus, words are maximally prevented from going out of a lecture subject and voice recognition correctness is increased. Moreover, the system includes a modification module such that initial, middle, and final sounds of each syllable forming a word detected by an error detection module are differently marked in accordance with a matching degree with a word detected by a related word detection module to enable a user to check a mark and correct the text through a user correction module. Therefore, a user′s processing time is reduced.
