Abstract: A digital dictation system having plural ports through which dictate and transcribe stations may be connected to a central store via respective dictate and transcribe channels for recording and transcribing messages. The transcribe port may be selectively conditioned, as by operating a manual selector, for enabling a dictate station to be connected therethrough to carry out dictate operations with the central store. Upon release of the port by the dictate station, the port reverts to its normal transcribe condition. By providing at least two ports, separate dictate and transcribe operations may be carried out concurrently on the same message. A dictator may review and edit a portion of the message which has already been transcribed by the transciptionist, whereupon the system automatically conditions the transcribe apparatus to play back the edit.

Abstract: A dictation system having two or more recording units, each selectively operable as a dictation unit or a transcription unit, and including a selector for selecting a respective unit for recording or transcription. A unit selected for recording dictation is enabled if a record medium therein is ready, or initialized, for recording; otherwise the unit is enabled for transcription. While one unit operates to record dictation, the other may operate simultaneously to transcribe previously recorded dictation. In a system having at least three recording units, at least two are identified with respective, particular identities and the third is designated a spare recording unit. After a predetermined amount of dictation has been recorded on any one of the identified recording units, further dictation destined for that identified unit is recorded on the spare unit, and the identity of the spare unit is charged over to be equal to the identity of the recording unit for which dictation had been intended.

Abstract: Dictate/transcribe apparatus in which plural modules, each including at least two record/playback decks, are interconnected. A switch in each module selects one or the other or neither of the decks therein to operate in a transcribe mode; and a transducer and operation selector are connected to one of the modules to effect a transcribe operation from the deck which has been selected to operate in the transcribe mode regardless of the particular module in which that deck is located. The electrical coupling arrangement between the modules permits audio signals to be transmitted from the transcribe deck to the particular module to which the transducer and operation selector are connected, and also allows function control signals to be transmitted from the operation selector to the module which includes the transcribe deck.
