Information processing system which can handle voice or image data

摘要

A schedule management system which can display a schedule on a screen and enables the user to enter schedule topics promptly and accurately without performing complicated operation is provided. An external voice is input through a microphone or a network control unit and is converted into a digital signal by an A/D converter and a coder. An identifier related to the digital signal is generated. The identifier is displayed on a schedule on a display unit. The digital signal is stored in a memory in relation to the identifier. A user specifies the displayed identifier through an operation section, whereby the digital signal related to the identifier is extracted from the memory by a CPU, the extracted digital signal is converted into an analog signal by a D/A converter, and the analog signal is output as a voice through a loudspeaker or the network control unit to the outside. Like a voice, an image can also be handled.
