摘要
Disclosed are a system for grasping keyword extraction based speech content on recorded voice data, an indexing method using the system, and a method for grasping speech content. An indexing unit receives voice data, performs per-frame voice recognition with reference to a phoneme to form a phoneme lattice, generates divided indexing information for a frame of a limited time configured with a plurality of frames, and stores the same in an indexing database, the divided indexing information including a phoneme lattice formed for each frame of the limited time. A searcher uses a keyword input by a user as a search word, performs a comparison on the divided indexing information stored in the indexing database with reference to a phoneme, searches a phoneme string matching the search word, and finds a voice portion corresponding to a search word through a precise acoustic analysis regarding the matching phoneme string, and the grasper grasps a representative word through a search result searched by the searcher and outputs it to the user so as to grasp speech content of the voice data.
