An audio message storing circuit and control method therefor in a video cassette recorder capable of recording audio information simultaneously with a timer program and outputting said stored audio information at the programmed time by means of a speaker. The circuit comprises: key matrix (1), timer microcomputer (2), communication processor (3), microphone (4), analog/digital converter (5), RAM (6), gate and hold circuit (7), digital/analog converter (8), low band pass filter (9), amplifier (10), and speaker (11). The control method comprises storing audio information in the RAM after converting to a digital signal, setting a timer program, reading out the stored information sequentially and then converting to analog signal and outputting through the speaker at the programmed time. <IMAGE> |
