SPONSORSHIP CREDIT PERIOD IDENTIFICATION APPARATUS, SPONSORSHIP CREDIT PERIOD IDENTIFICATION METHOD AND PROGRAM

摘要

A credit segment identifying device includes an extracting unit which extracts, from a first speech signal, a plurality of first partial speech signals which are each a part of the first speech signals and shifted from each other in time direction and an identifying unit which identifies a credit segment in the first speech signal by determining whether each of the first partial speech signals includes a credit according to an association between each of second partial signals extracted from a second speech signal and the presence/absence of a credit, so that credit segments can be identified more efficiently.
