Abstract

A text content summary is created from speech content. A focus more signal is issued by a user while receiving the speech content. The focus more signal is associated with a time window, and the time window is associated with a part of the speech content. It is determined whether to use the part of the speech content associated with the time window to generate a text content summary based on a number of the focus more signals that are associated with the time window. The user may express relative significance to different portions of speech content, so as to generate a personal text content summary.

Claims

1. A system for generating a text content summary from speech content, comprising:

a processor; and

memory connected to the processor, wherein the memory is encoded with instructions and wherein the instructions when executed comprise;

instructions for receiving speech content;

responsive to reception of at least one focus more signal issued by a user, instructions for associating said at least one focus more signal with a first time window, wherein said first time window is associated with a first portion of said speech content; and

instructions for determining whether to use said first portion of said speech content associated with said first time window to generate a text content summary based on how many of said at least one focus more signal are associated with said first time window.

2. The system of claim 1, wherein said instructions for determining whether to use said first portion of said speech content comprises instructions for calculating a first focus level value PT, wherein PT=P0+N/T, of said first portion of said speech content associated with said first time window, wherein P0 indicates a default focus level value, T indicates a length of said first time window, and N indicates a number of said at least one focus more signal, and said first focus level value PT of said first portion of said speech content associated with said first time window is ordered so as to use said first portion of said speech content when said first focus level value PT is greater when compared with any other portions of said speech content to generate said text content summary.

3. The system of claim 2, further comprising:

responsive to reception of at least one focus less signal issued by a user, instructions for associating said at least one focus less signal with a second time window, wherein said second time window is associated with a second portion of said speech content; and

instructions for determining whether to use said second portion of said speech content associated with said second time window to generate said text content summary based on how many of said at least one focus less signal are associated with said second time window.

4. The system of claim 3, wherein said instructions for determining whether to use said second portion of said speech content comprises instructions for calculating a second focus level value PT, wherein PT=P0+(N−

M)/T, of said second portion of said speech content associated with said second time window, wherein, P0 indicates a default focus level value, T indicates a length of said second time window, N indicates number of said at least one focus more signal, and M indicates number of said at least one focus less signal, and said second focus level value PT of said second portion of said speech content associated with said second time window is ordered so as to use speech content portions with a relatively larger focus level value PT to generate said text content summary.

5. The system of claim 4, wherein a counting device sums a number of said at least one focus more signal associated with its time window.

6. The system of claim 5, wherein said counting device also sums a number of said at least one focus less signal associated with its time window.

7. A method for generating a text content summary from speech content, comprising:

receiving speech content;

responsive to reception of at least one focus more signal issued by a user, associating, using a processor, said at least one focus more signal with a first time window, wherein said first time window is associated with a first portion of said speech content; and

determining, using said processor, whether to use said first portion of said speech content associated with said first time window to generate a text content summary based on how many of said at least one focus more signal are associated with said first time window.

8. The method of claim 7, wherein said associating said at least one focus more signal with a first time window further comprises:

determining whether there is currently an active time window;

when it is determined there is no currently active time window, generating an active time window, and setting said at least one focus more signal associated with said active time window to 1, wherein said active time window has a start time and an end time, and before arrival of said end time, said active time window is active; and

when it is determined there is a currently active time window, incrementing a number of said at least one focus more signal associated with said active time window by 1.

9. The method of claim 8, wherein said determining comprises calculating a first focus level value PT, wherein PT=P0+N/T, of said first portion of said speech content associated with said first time window, wherein, P0 indicates a default focus level value, T indicates a length of said first time window, N indicates a number of said at least one focus more signal, and said first focus level value PT of said first portion of said speech content associated with said first time window is ordered so as to use speech content when said first focus level value PT is larger when compared with other portions of said speech content in order to generate said text content summary.

10. The method of claim 9, further responsive to reception of at least one focus less signal issued by a user:

associating said at least one focus less signal with a second time window, wherein said second time window is associated with a second portion of said speech content; and

determining whether to use said second portion of said speech content associated with said second time window to generate said text content summary further comprises determining a number of said at least one focus less signal associated with said second time window.

11. The method of claim 10, wherein said instructions for determining whether to use said second portion of said speech content comprises instructions for calculating a second focus level value PT, where PT=P0+(N−

M)/T, wherein, P0 indicates a default focus level value, T indicates a length said second time window, N indicates a number of said at least one focus more signal, and M indicates a number of said at least one focus less signal, and said second focus level value PT of said second portion of speech content associated with said second time window are ordered so as to use said speech content portions with a relatively larger focus level value PT to generate a text content summary.

12. The method of claim 11, further comprising instructions for counting a number of said at least one focus more signal associated with said time window.

13. The method of claim 12, wherein said instructions for counting also sums a number of said at least one focus less signal associated with said time window.

14. A computer program for generating a text content summary from speech content, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:

computer readable program code configured to receive speech content;
