System and method for identifying an identical audio segment using text comparison

Abstract

A method for comparing text in a first file to text in a second file. The method includes segmenting text in the first and second files to one word per line; comparing the segmented versions of the versions of the first and second files on a line by line basis; creating a result file using the segmented version of the first file; and augmenting the result file with indication of error using a sandwiching technique. This sandwiching technique includes identifying correct segments that are immediately adjacent any differences identified by comparing the segmented versions of the first and second files on a line by line basis toward sandwiching the erroneous segments between correct segments. Said method incorporates video monitor (26), keyboard (24), and mouse (23), along with microphone (25) and digital recorder (14) for implementing the invention.
