Abstract

A method and system is provided to monitor speech and detect keywords or phrases in the speech, such as for example, monitored calls in a call center or speakers/presenters using teleprompters, or the like. Upon detection of the keywords of phrases, information associated with the keywords or phrases may be presented to a display device so that a user may dynamically receive new information as context of the speech progresses. This provides dynamic information as the context of the conversation develops. The information may be presented as links, cues, text, or similar formats. The detected keywords or phrases may also be associated with rules that govern the conditions and criteria for processing the detected keyword and presentation of the information.

Claims

1. A method for dynamically detecting topics, comprising:

predefining one or more keywords relevant to a context of a conversation;

associating information with the one or more keywords;

detecting at least one of the one or more keywords in speech; and

recording that at least one of the one or more keywords has been detected.

2. The method of claim 1, further comprising:

checking whether one or more rules are associated with the at least one detected keyword; and

if so, processing the one or more rules.

3. The method of claim 2, wherein the one or more rules govern the conditions when the information associated with at least one of the detected keywords may be provided.

4. The method of claim 2, wherein the one or more rules control the processing of a call flow sequence.

5. The method of claim 2, wherein the one or more rules dynamically check environmental conditions.

6. The method of claim 1, further comprising:

associating information with the one or more keywords; and

providing the information associated with at least one of the detected keywords.

7. The method of claim 6, further comprising extracting the information from a database.

8. The method of claim 6, wherein the providing provides the information on a display device.

9. The method of claim 6, wherein the information includes at least any one of text, video, graphics, a link, a navigation tab, and animation.

10. The method of claim 1, further comprising monitoring at least any one of a telephone call, an audio input, and a recording as a source of the speech.

11. The method of claim 10, wherein the monitoring includes monitoring a call delivered via one of a network, a digital phone line, an analog line, a voice-over-internet protocol (VOIP).

12. The method of claim 1, further comprising building a database indexed by the one or more keywords.

13. The method of claim 1, wherein the one or more keywords comprise one or more phrases and the detecting detects the one or more phrases.

14. The method of claim 1, further comprising:

displaying the one or more keywords on a display; and

marking the one or more keywords on the display when the one or more keywords has been detected.

15. A method for monitoring voice, comprising:

monitoring speech for a pre-defined keyword or phrase;

detecting the pre-defined keyword or phrase;

determining whether a rule is associated with the detected pre-defined keyword or phrase; and

processing the rule when the rule is determined to be associated with the predefined keyword or phrase.

16. The method of claim 15, further comprising providing information associated with the detected pre-defined keyword or phrase.

17. The method of claim 15, wherein the rule controls processing of a call.

18. The method of claim 15, wherein the rule defines criteria for presenting the information.

19. The method of claim 15, further comprising accessing a database to determine whether the rule is associated with the keyword or phrase.

20. The method of claim 15, further comprising accessing a database indexed by the keyword or phrase.

21. The method of claim 15, wherein the rule spawns new keywords or phrases to be monitored.

22. A system for monitoring speech, comprising at least one component to:

predefine one or more keywords relevant to a context of a conversation;

associate information with the one or more keywords;

detect at least one of the keywords in speech; and

provide the information associated with at least one of the detected keywords.

23. The system of claim 22, further comprising the at least one component to:

check whether one or more rules are associated with the at least one detected keyword; and

if so, process the one or more rules.

24. The system claim 23, wherein the one or more rules govern the conditions when the information associated with at least one of the detected keywords may be provided.

25. The system of claim 23, wherein the one or more rules control the processing of a call flow sequence.

26. The system of claim 23, wherein the one or more rules dynamically check environmental conditions.

27. The system of claim 22, wherein the information includes at least one of text, video, graphics, a link, a navigation tab, and animation.

28. The system of claim 22, further comprising the at least one component to monitor at least one of the group a telephone call, audio input, and a recording as a source of the speech.

29. The system of claim 28, wherein the at least one component monitors the telephone call delivered via one of a network, a digital phone line, an analog line, a voice-over-internet protocol (VOIP).

30. The system of claim 29, wherein the at least one component extracts the information from a database.

31. The system of claim 22, wherein the at least one component provides the information on a display device.

32. The system of claim 22, wherein the at least one component builds a database indexed by the one or more keywords.

33. The system of claim 22 wherein the one or more keywords comprise one or more phrases and the at least one component detects the one or more phrases.

34. The system of claim 22, wherein the at least one component:

displays the one or more keywords on a display; and

marks the one or more keywords on the display when the one or more keywords has been detected.

35. A computer program product comprising a computer usable medium having readable program code embodied in the medium, the computer program product includes at least one component to:

predefine one or more keywords relevant to a context of a conversation;

associate information with the one or more keywords;

detect at least one of the keywords in speech; and

provide the information associated with at least one of the detected keywords.
