<p>PURPOSE:To prevent excessive memories of a communication controller, by storing an audio information both to an electronic computer and the controller and editing both the audio information, in a system of audio response from an information center to a terminal device. CONSTITUTION:When an audio response message selecting command is transmitted from an electronic computer CPU, a processor PU in a communication controller CCU stores a command to a control buffer for the corresponding line of a memory MEM. A control program sets a memory address and number of bytes in a voice adaptor VOA and requests data transfer to the voice memory VOM, and the data read out from the memory VOM is converted into an audio information at a D/A converter and transmitted via a selector switch SW. When the number of bytes specified is read out from the memory VOM, interruption is made to the processor PU, which requests data transfer to the CPU via a sub-channel to make D/A conversion through the transfer of the voide information of a given number.</p> |
