Abstract

A method for spotting an interaction in which a target speaker associated with a current index or current interaction speaks, the method comprising: receiving an interaction and an index associated with the interaction, the index associated with additional data; receiving the current interaction or current index associated with the target speaker; obtaining current data associated with the current interaction or current index; filtering the index using the additional data, in accordance with the current data associated with the current interaction or current index, and obtaining a matching index; and comparing the current index or a representation of the current interaction with the matching index to obtain a target speaker index.

Claims

1. A method for spotting at least one interaction in which an at least one target speaker associated with a current index or current interaction speaks, the method comprising:

receiving at least one interaction and an at least one index associated with the at least one interaction, the at least one index o associated with additional data;

receiving the current interaction or current index associated with the at least one target speaker;

obtaining current data associated with the current interaction or current index;

filtering the at least one index using the additional data, in accordance with the current data associated with the current interaction or current index, and obtaining a matching index; and

comparing the current index or a representation of the current interaction with the matching index to obtain at least one target speaker index.

2. The method of claim 1 further comprising generating the at least one index associated with the at least one interaction.

3. The method of claim 1 further comprising taking an action associated with the at least one interaction associated with the matching index.

4. The method of claim 1 wherein the at least one index comprises an acoustic feature.

5. The method of claim 1 wherein the at least one index comprises a non-acoustic feature.

6. The method of claim 1 wherein the additional data comprises acoustic data.

7. The method of claim 1 wherein the additional data comprises non-acoustic data.

8. The method of claim 1 further comprising obtaining a comparison score.

9. The method of claim 1 further comprising outputting the at least one interaction associated with the at least one target speaker index, in accordance with the comparison results.

10. The method of claim 1 wherein the representation of the current interaction is an index of the current interaction.

11. An apparatus for spotting an at least one interaction in which an at least one target speaker speaking associated with a current interaction or current index, comprising:

a calls database for storing an at least one interaction;

an index database for storing an at least one index associated with the at least one interaction, wherein the at least one index is associated with additional data;

a filtering component for filtering the at least one index using the additional data, in accordance with current data associated with the current interaction or current index, and obtaining a matching index; and

a comparison component for comparing the current index or a representation of the current interaction with the matching index, and obtaining a target speaker index.

12. The apparatus of claim 11 further comprising an index generation component for generating the at least one index associated with the at least one interaction.

13. The apparatus of claim 11 wherein the at least one index is associated with additional data.

14. The apparatus of claim 11 further comprising an action handler for taking an action associated with the at least one interaction associated with the target speaker index.

15. The apparatus of claim 11 wherein the at least one index comprises an acoustic feature.

16. The apparatus of claim 11 wherein the at least one index comprises a non-acoustic feature.

17. The apparatus of claim 11 wherein the additional data comprises acoustic data.

18. The apparatus of claim 11 wherein the additional data comprises non-acoustic data.

19. The apparatus of claim 11 further comprising a user interface for outputting at least one interaction associated with the target speaker index.

20. A non-transitory computer readable storage medium containing a set of instructions for a general purpose computer, the set of instructions comprising:

receiving at least one interaction and an at least one index associated with the at least one interaction, the at least one index associated with additional data;

receiving a current interaction or current index associated with a target speaker;

obtaining current data associated with the current interaction or current index;

filtering the at least one index using the additional data, in accordance with the current data associated with the current interaction or current index, and obtaining a matching index; and

comparing the current index or a representation of the current interaction with the matching index to obtain at least one target speaker index.
