Apparatus for controlling digital voice recording and playback over telephone lines and adapted for use with standard host computers
First Claim
1. In a system for digital recording and playback of voice messages and that includes a host computer, a telephone interface to telephone lines, and a voice processor, the voice processor being connected to the telephone interface by analog audio lines for transmitting voice messages therebetween and having means for converting voice messages into digital signals and for converting digital signals into voice messages, an electronic communications supervisor that is independent of said host computer and that is connected as communications intermediary between said host computer and said telephone interface and said voice processor, said supervisor comprising programmed digital signal processing means for controlling the operation of the supervisor and digital memory means for storing digital signals to be communicated under the control of said processing means, said supervisor having parallel means for communication of digital signals in parallel format with respect to both of said telephone interface and said voice processor, having serial means for communication of digital signals in serial format with respect to said host computer and having means for translating between said formats, said digital signal processing means controlling communication between said host computer, said telephone interface, and said voice processor.

Abstract
A method of enabling the efficient use of a standard host computer with a voice message processing apparatus using a telephone interface and voice processing system, that comprises, providing a universal supervisory circuit between the host computer and the telephone interface and voice processing system, the circuit having a memory that stores data of a type useful to interface with said telephone and voice processing interface system, the circuit performing the steps of receiving standard serial data from the host computer such as telephone answering, voice message storing and other commands; storing in the supervisory circuit memory particular serial data commands tailored to command and control the telephone interface and voice processing system; using the data stored in the memory to translate said received standard serial data from the host computer into command and control language recognizable by the telephone interface and voice processing system; converting the translated language into parallel data; and prioritizing the application of said parallel data to said telephone interface and voice processing system for efficient transmission to the telephone interface system; the telephone interface and voice processing system generating parallel data, such as line-ringing and other status data, translated by the supervisory circuit into standard serial data recognizable by the host computer; and prioritizing the transmission of the last-named standard serial data to the host computer.

7. A method of enabling the efficient use of a host computer with a voice message processing apparatus including a telephone interface to telephone lines and a voice processor connected to said telephone interface by audio signal lines, that comprises providing a programmed processor-controlled electronic communications supervisor independent of said host computer and connected as a communications intermediary between the host computer and the telephone interface and the voice processor, and performing the following steps with said supervisor:
controlling communication of digital signals in serial format with respect to said host computer, controlling communication of digital signals in parallel format with respect to said telephone interface and said voice processor, translating digital signals between said formats, whereby said host computer may communicate with said telephone interface and said voice processor, and controlling communication of voice messages between said voice processor and said telephone interface along said audio signal lines. - View Dependent Claims (8, 9, 10, 11)
