<P>PROBLEM TO BE SOLVED: To robustly determine an optimum synchronization time by collating event signal data with audio data which are obtained without being synchronized while shifting them with time. <P>SOLUTION: A data synchronizing device 10 is equipped with a section detection part 12 which detects voiced sections and voiceless sections of the audio data, a time difference setting part 15 which sets a plurality of synchronization time differences as temporal shifts when the audio data and event signal are synchronized with each other, a coincidence calculation part 14 which calculates the degree of coincidence by deciding temporal coincidences between a plurality of obtained event signals and voiceless sections detected by the section detection part by the plurality of synchronization time differences set by the time difference setting part 15, and a synchronism determination part 16 which determines the synchronization time between the audio data and event signal data from the degree of coincidence calculated by the coincidence calculation part 14. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
