Abstract

PURPOSE: To decrease the filing capacity by reproducing the necessary through isolation between the voice recorded first and the voice recorded in the non-sound section with detection of the control signal at the reproduction time.
CONSTITUTION: The voice is converted to the analog electric signal and supplied to input terminal 1, and the aural signal equivalent to one unit is stored in buffer memroy 3 after A/D conversion 2. Control unit 13 writes 1-unit data of memory 3 into file memory 6 via data compound circuit 4. Then the non-sound section is detected (8) for the voice recorded in memory 6, and other voice is recorded in the non-sound section along with the control signal. The control signal is selected (10) at the reproduction time, and then the voice recorded first is separated from the voice recorded at the non-sound section to reproduce the necessary voice. As a result, the filing capactity can be decreased.
