Abstract

In this telephone dictating system , remote stations including telephone handsets are selectively interconnected to a central recording apparatus by dialing the number of the subscriber's telephone set. After connection has been made, the subscriber, by dialing particular digits, controls the operation of the recording apparatus, for example, for dictation, play-back, erasing a record, and backward and forward stepping of the magnetic head. As a particular period of time elapses from dialing to the execution of an operation, the "Stop" operation is initiated by the voice of the listening subscriber to immediately stop the record media.

Voice Actuated Stop in Telephone Dictated System

In this telephone dictating system , remote stations including telephone handsets are selectively interconnected to a central recording apparatus by dialing the number of the subscriber's telephone set. After connection has been made, the subscriber, by dialing particular digits, controls the operation of the recording apparatus, for example, for dictation, play-back, erasing a record, and backward and forward stepping of the magnetic head. As a particular period of time elapses from dialing to the execution of an operation, the "Stop" operation is initiated by the voice of the listening subscriber to immediately stop the record media.

The drawing shows central dictating unit 1 which is connected to remote stations A to D, via exchange 2. Assuming a subscriber of station A has picked up his handset, pulses of the dial digits (for example, digit 1 for "recording", digit 2 for "play-back", digit 3 for "forward stepping", digit 4 for "backward stepping") are fed, via exchange 2 to operation signal control unit 3 which controls the operation of recording apparatus 4.

In the play-back mode, operation control 3 connects recording apparatus 4 with its input 6, via switch 5, to output 7 of channel filter 8 and with its input 9, via voice detector 10 and switch 11, to output 12 of channel filter 8. Thus, audio signals emitted by recording apparatus 4 are transferred by means of circuit 8 to subscriber A only. Audio signals...
