Abstract

A transcription interface (10), connected to a general purpose digital computer (11) and a digital dictation recorder (20), for controlling various transcription functions and for automatically transferring information concerning dictation from the recorder (20) to an application program running on the digital computer (11). The recorder (20) generates a sequence of digitized dictation signals including a dictation segment and a digitized identification signal containing information corresponding to the dictation segment. The transcription interface (10) supplies an audio signal to an audio port (43) by converting the digital dictation signal to a signal that audibly reproduces the dictation for transcribing by a transcriptionist. The transcription interface (10) also formats the digitized identification signal to generate a message signal having a signal format compatible with the interface (10). In response to an interrupt signal generated by a timer interrupt circuit (17) of the computer (11), the transcription interface (10) automatically sends the message signal to an application program running on the computer (11) for display by a video display (14) connected to the computer (11). In response to an interrupt signal generated by the application program, the transcription interface (10) supplies a status signal containing information concerning the operation of the application program to the recorder (20). The operation of certain keys on a keyboard (13) connected to the computer (11) generates keyboard interrupts that initiate various transcription control functions by the transcription interface (10).
