Abstract

A telephonic data communications system provides verbal communication of data in remote computer systems. The major components of the systems are a plurality of channels and a data processor. Each channel includes a text-to-speech translator for translating digitally stored textual data into analogue speech signals corresponding to the verbal expression of the textual data; a telephone interface for establishing a telephonic connection with a user by detecting incoming calls and by initiating calls; and an RS232 port for accessing a data base in a remote host computer system. The data processor includes software for controlling the communications protocols used by each channel, whereby each channel emulates a computer terminal suitable for communication with the remote computer system connected to that channel, and software for extracting selected data from the data received from the remote computer system. This system enables one to telephonically receive data from a remote computer without the need for a computer terminal and without needing to reprogram the remote computer to communicate with the telephonic data communication system.

Claims

1. A communications system for verbal telephonic communication of textual data in remote computer systems, comprising:

(a) text-to-speech (TTS) means for translating digitally stored textual data into analogue speech signals corresponding to the verbal expression of said textual data;

(b) telephone call handling means for initiating telephone calls and receiving data requests from the telephone answerer, including

means for initiating a telephone call and establishing a telephonic connection with the answerer; and

instruction means for receiving and interpreting instructions from said answerer, said instructions including commands specifying what data to retrieve;

(c) data base access means for accessing a data base in a separate computer system, including

means for establishing a connection with a separate computer system;

means for emulating a computer terminal suitable for communication with said separate computer system; and

means for requesting and receiving data from a data base in said separate computer system; and

(d) data delivery means, including

means, responsive to said instructions from said answerer, for extracting a portion of said data, wherein said portion of said data is selected in accordance with said instructions received from said answerer; and

means for routing said portion of said data to said TTS means for translation thereby; and

means for routing said speech signals from said TTS means to said answerer by means of said telephonic connection.

2. A communications system as set forth in claim 1, wherein

said telephone call handling means further includes means for detecting an incoming telephone call and establishing a telephone connection with the caller;

and

said instruction means receives and interprets instructions from said caller; and

said data delivery means is responsive to instructions from said caller and routes said speech signals to said caller.

3. A communications system as set forth in claim 2, wherein

said means for extracting includes means for interpreting said data received from said remote computer system as a screen image and means for extracting a predefined portion of said screen image.

4. A communications system as set forth in claim 1, wherein

said instruction means includes

means for interrupting the verbal transmission of data to said answerer and means for respecifying the data to be retrieved;

and

rate changing means for specifying that the rate of verbal transmission be increased or decreased; and

said data delivery means includes means responsive to said rate changing means for controlling the rate of verbal transmission to said answerer.

5. A communications system as set forth in claim 1, wherein

said means for extracting includes means for interpreting said data received from said remote computer system as a screen image and means for extracting a predefined portion of said screen image.

6. A communication system for verbal telephonic communication of textual data in remote computer systems, comprising:

(a) a plurality of channel means, each channel means including;

(1) text-to-speech (TTS) means for translating digitally stored textual data into analogue speech signals corresponding to the verbal expression of said textual data;

(2) telephone call handling means, including

means for initiating a telephone call and establishing a telephonic connection with the answerer; and

instruction means for receiving instructions from said answerer specifying what data to retrieve;

(3) data base access means for accessing a data base in a separate computer system, including

means for establishing a connection with a separate computer system;

(b) data processing means coupled to said plurality of channel means, including a single central processor unit having a set of routines for

(1) controlling the communications protocols used by the data base access means in each said channel, whereby each said data base access means emulates a computer terminal suitable for communication with said separate computer system connected thereto; and

(2) in accordance with said instructions from said answerers to each said channel means, extracting a portion of the data received from said separate computer system connected to each said channel means and routing said extracted data to the TTS means of the channel means which received said data, wherein said portion of said data is selected in accordance with said instructions received from said answerer to said channel means.

7. A communications system as set forth in claim 6, wherein

said telephone call handling means in at least one of said channel means further includes means for detecting an incoming telephone call and establishing a telephone connection with the caller;

and

said data processing means includes means responsive to instructions from said caller to at least one of said channel means for extracting a portion of the data received from said separate computer system connected to each said channel means and routing said extracted data to the TTS means of the channel means which received said data, wherein said portion of said data is selected in accordance with said instructions received from said caller to said channel means.

8. A communication system as set forth in claim 7, wherein

said data extraction means includes means for interpreting data received from at least one of said remote computer systems as a screen image and means for extracting a predefined portion of said screen image.

9. A communications system as set forth in claim 8, wherein

each said channel means can be connected to a distinct remote computer system, and each said data processing means can perform a distinct data extraction task corresponding to the particular data base being accessed.

10. A communication system as set forth in claim 6, wherein

said data processing means includes a multitasking operating system having a separate task defined for each said channel means.

11. A communications system as set forth in claim 6, wherein

each said channel means can be connected to a distinct remote computer system, and each said data processing means can perform a distinct data extraction task corresponding to the particular data base being accessed.

12. A communications system as set forth in claim 6, wherein

said data extraction means includes means for interpreting data received from at least one of said remote computer systems as a screen image and means for extracting a predefined portion of said screen image.
