<P>PROBLEM TO BE SOLVED: To easily create image data with sound having the presence. <P>SOLUTION: A sound synthesizing unit 14 reads, from a sound data storage unit 16, sound source data relating to a speech object displayed on a display device 4 and if the sound source data are text, sound data are created based on the text. If a direction vector of a speech object, read from a speech object direction storage unit 17, relating to the relevant speech object is in the same direction as the direction of a viewer, for example, a sound data working unit 13 suppresses a high frequency component by low-pass-filtering the sound data from the sound synthesizing unit 14. Thus, utterance sound is made more indistinct than that in a case where the speech object faces the viewer each other, thereby displaying an image with sound having the presence for the viewer. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
