COLLATION SYSTEM OF VOICE KEYWORD IN VOICE DATA, METHOD THEREOF, AND COLLATION PROGRAM OF VOICE KEYWORD IN VOICE DATA

摘要

PROBLEM TO BE SOLVED: To achieve collation of voice keyword in voice data with a practical search precision without requiring voice recognition processing by a highly versatile and simple configuration.;SOLUTION: The collation system includes: a voice waveform-combining part which combines a standard voice waveform pattern and a plurality of derived voice waveform patterns different from the standard voice waveform pattern in speed and/or volume, from an input search keyword text; a similarity threshold calculation part which variably sets a similarity threshold for collation by raising or reducing a reference threshold; and a voice keyword collation part which refers to a voice keyword database and successively compares the standard voice waveform pattern and the plurality of derived voice waveform patterns with a voice waveform pattern of read voice data to calculate similarities and obtains positions of voice keywords of which the calculated similarities are equal to or higher than the similarity threshold.;COPYRIGHT: (C)2011,JPO&INPIT
