PURPOSE:To enable just a single worker to perform a call test for a hand-free type telephone at a high speed and high efficiency, by using a voice registering/ reproducing device. CONSTITUTION:A test operator 25 first turns on a voice recording switch 23 of a test material 30 and speaks to a mike 3 for a fixed period of time. A tester 30 receives these voice signals through a call line 26 and converts them into digital signals to store them temporarily to a memory 36. Then the operator 25 turns off the switch 23 and this OFF signal is detected by a memory controller 35, and the voice data written previously to the memory 36 are read out successively. These read-out voice data are reproduced and sent to a telephone 1 to be tested. Thus the operator 25 can hear the voice signals from a call line 26 through a speaker 2 with the telephone 1 by changeover of a voice switch 19. |
