<P>PROBLEM TO BE SOLVED: To enable a reproduced sound, in a karaoke device which reproduces a raw sound data obtained by recording a musical performance, to be heard acoustically natural when a music interval is changed. <P>SOLUTION: The karaoke device executes: a filter generation process for generating filter characteristics for maintaining formant characteristics by analyzing raw sound data; a determination process for determining pronunciation information to be reproduced from music data based on the filter characteristics generated in the filter generation process, a music interval input through an input unit, and music data; a raw sound reproduction process for allowing, based on the music interval input through the input unit, a raw sound reproduction unit to reproduce the raw sound data by changing the music interval of the raw sound data and by applying the filter characteristics generated in the filter generation process; a music reproduction process for allowing, based on the music interval input through the input unit, a music reproduction unit to reproduce the pronunciation information determined in the determination process. <P>COPYRIGHT: (C)2012,JPO&INPIT |
