格アップとなってい友。Conventionally, in voice storage and playback systems, for example, without being particularly conscious of information on the presence or absence of audio signals or silence information, during a call from call origination to end of call, silent pattern information is stored in the file memory. Ta. Therefore,
File memory requires a large storage capacity, which increases the price of the device.

Create a set clock with a period of seconds. When the sound/silence detection circuit 24 receives the set clock, the detection circuit starts and detects whether the input analog audio signal is sound information or silence information. When detecting sound information, it rises to 1,
For silence information, the oy ratio is output. The 7-rip 7-rip FF of 1 bit' is held set upon reception of the set clock, takes in sound information, and after the control device 12 reads the information t-, sends a reset signal to the all-iron flip-flop 2F to reset it. On the other hand, the analog audio signal is sent to the analog-to-digital converter 2.
1 and after t, the serial/parallel converter 22t-
The data is sent to the transfer storage via the controller 12, and transferred to the primary storage device 10 as a DMA transfer (direct memory access transfer) every n seconds under the control of the control device 12.
