<p>PURPOSE:To output simultaneously different voice messages from plural speakers and to output a high-priority message preferentially when the high-priority message is generated, by interrupting a low-priority message by managing a request registration order independently for every speaker. CONSTITUTION:When an application program voice reporting request 1' in each of CPUs A4, B5, and C6 is issued, it is reported to a controller 13 through a transmission line 12 and is registered in a request queue SPj14 for every speaker. The controller 13 searches successively the request queue 14 and takes out them in order from the oldest request and retrieves a message file 1 and a tuning bar file 2 in an external storage device 3 to a voice output message and outputs voice data to a voice output control part 15 of a designated output speaker SPj11. The control part 15 converts this voice data to an audio signal to output a reporting message to the speaker SPj11. Since parallel output processings are possible in each speaker SPj11, both outputs are continued without the influence upon one speaker output when a high-priority message is generated.</p> |
