Abstract

A computer workstation supports speech recognition software 50 and conferencing software 45, and is involved in an audio conference with one or more other workstations. Speech from the user at that workstation is transmitted to the other workstation(s), and also converted into text by the speech recognition software. The conferencing software then transmits the text to the other workstation(s). Likewise, the conferencing software also receives the text equivalent of spoken contributions from the other workstation(s). This received text, together with the locally generated text, is stored in a text file so as to produce a set of minutes for the audio conference.

Claims

1. A method of textually recording at a workstation spoken contributions to an audio conference, each participant in the conference having an associated workstation, the workstations being linked together by one or more networks, the method comprising the steps of:

receiving local speech input at the workstation;

performing speech recognition on the local speech input at the workstation to generate a local text equivalent;

transmitting the local speech input to the other participant(s) in the conference;

receiving spoken contributions from the other participant(s) in the conference plus the corresponding text equivalents transmitted from the workstation associated with the respective participant;

storing both the local text equivalents and the text equivalents received from the other workstation(s) in a text file.

2. The method of claim 1, wherein each text equivalent of a spoken contribution stored in said text file is accompanied by the time of the contribution and/or an indication of the origin of that spoken contribution.

3. The method of claim 1 further comprising the step of transmitting the local text equivalent of said local speech input to the other workstation(s) in the conference.

4. The method of claim 3 wherein said step of transmitting the local text equivalent to the other workstations occurs regularly after a predetermined time interval.

5. The method of any preceding claim, further comprising the step of visually displaying at the workstation both the local text equivalents and the text equivalents received from the other workstation(s).

6. The method of claim 5, wherein each text equivalent of a spoken contribution is displayed accompanied by the time of the contribution and/or an indication of the origin of that spoken contribution.

7. The method of claim 6, wherein the text equivalents are visually displayed in a set of parallel columns, whereby each column displays the text equivalents of the spoken contributions from a single workstation.

8. The method of claim 7, further including the step of adjusting the cursor position within each of the columns after each new spoken contribution has been displayed to maintain horizontal alignment between the columns with regard to time synchronisation.

9. The method of claims 6, 7 or 8 further comprising the step of editing said text file.

10. The method of any of claims 1,2,3 or 4 wherein the text recording can be turned on and off during the audio conference.

14. The method of claim 2, further comprising the step of transmitting the local text equivalent of said local speech input to the other workstation(s) in the conference.

15. The method of claim 14 further comprising the step of visually displaying at the workstation both the local text equivalents and the text equivalents received from the other workstation(s).

16. The method of claim 15 wherein the text recording process can be turned on and off during the audio conference.

11. A system for textually recording at a workstation spoken contributions to an audio conference, each participant in the conference having an associated workstation, the workstations being linked together by one or more networks, the method comprising the steps of:

means for receiving local speech input at the workstation;

means for performing speech recognition on the local speech input at the workstation to generate a local text equivalent;

means for transmitting the local speech input to the other participant(s) in the conference;

means for receiving spoken contributions from the other participant(s) in the conference plus the corresponding text equivalents transmitted from the workstation associated with the respective participant;

means for storing both the local text equivalents and the text equivalents received from the other workstation(s) in a text file.

12. The system of claim 11, further comprising means for transmitting the local text equivalent of said local speech input to the other workstation(s) in the conference.

13. The system of claim 11 or claim 12, further comprising means for visually displaying at the workstation both the local text equivalents and the text equivalents received from the other workstation(s).
