<p>PURPOSE:To easily recognize the correspondence of an icon image to a silent voice signal without damaging the hearing of a voice under sounding when displaying this icon image without displaying another document or the like in the case of displaying the document in a prescribed window and sounding the voice corresponding to this document, etc. CONSTITUTION:The voice signal not to be sounded from a speaker 9 is selected by a voice signal selector 11. A voice information extracting means 3 extracts real-time information such as a volume level, for example, from the selected voice signal not to be sounded. Corresponding to the extracted real-time information, an icon image generating means 4 generates the dynamic icon image which size is enlarged/reduced with the passage of time, and this icon image is displayed through an image synthesizing means 6 and a display device control means 5 onto the screen of a display device 2. Therefore, the size of the dynamic icon image is enlarged/reduced corresponding to the volume level of the voice signal not to be sounded.</p> |
