Abstract

A method for processing a call is disclosed. The method receives a speech input in connection with a call and transforms at least a segment of the speech input into a first textual format. The method also generates a first list of entries based, at least partially, on a consideration of the first textual format, the first list comprising at least one action with a corresponding confidence level and at least one object with another corresponding confidence level, selects an entry of the first list having a higher corresponding confidence level, outputs a second textual format. The method further generates a second list based, at least partially on consideration of the selected entry and the second textual format and suggesting a routing option for the call based on the selected entry and a pairing entry in the second list having a high corresponding confidence level.

Claims (36)

1. A method for processing a call comprising:

receiving a speech input in connection with a call;

transforming at least a segment of the speech input into a first textual format;

generating a first list of entries based, at least partially, on a consideration of the first textual format, the first list comprising at least one action with a corresponding confidence level and at least one object with another corresponding confidence level;

selecting an entry of the first list having a higher corresponding confidence level;

outputting a second textual format;

generating a second list based, at least partially on consideration of the selected entry and the second textual format; and

suggesting a routing option for the call based on the selected entry and a pairing entry in the second list having a high corresponding confidence level.

2. The method of claim 1 , further comprising re-processing the speech input to create an object list when an action is the selected entry.

3. The method of claim 1 , further comprising re-processing the speech input to create an action list when an object is the selected entry.

4. The method of claim 2 , further comprising:

including an associated confidence level with an object entry in the object list; and

selecting an object as the pairing entry based on the associated confidence level.

5. The method of claim 3 , further comprising:

reprocessing the speech input to produce the action list with confidence levels; and

selecting an action based on the confidence levels in the action list.

6. The method of claim 1 , further comprising comparing the first textual format to a list of word strings and assigning a probability to at least one word string included in the list of word strings.

7. The method of claim 6 , further comprising assigning an appropriate confidence level to the at least one word string.

8. The method of claim 1 , wherein the entry selected is one of a verb and an adverb-verb combination.

9. The method of claim 1 , wherein the entry selected is one of a noun or an adjective-noun combination.

10. The method of claim 1 , further comprising utilizing a synonym table to assist in converting the speech input into action and objects.

11. A computer readable medium tangibly embodying a program of instructions to manipulate a processor to:

receive a speech input in connection with a call;

transform at least a portion of the speech input into a first textual format;

generate a first list based, at least partially, on a consideration of the first textual format, the list comprising at least one action with a corresponding confidence level and at least one object with its own corresponding confidence level;

select an entry of the first list having a high corresponding confidence level;

transform at least some of the speech input into a second textual format;

generate a second list based, at least partially on consideration of the selected entry and the second textual format, wherein entries in the second list have corresponding confidence levels; and

suggest a routing option for the call based at least partially on the selected entry and a pairing entry in the second list having a corresponding confidence level above a threshold value.

12. The computer readable medium of claim 11 , further including instruction to re-process the speech input to create a list of potential objects to pair with an action when the action is the selected entry from the first list.

13. The computer readable medium of claim 11 , further including instructions to re-process the speech input to create a list of potential actions when an object is the selected entry from the first.

14. The computer readable medium of claim 12 , further including instructions to produce confidence levels of objects in the object list; and to select an object based on the object list confidence levels.

15. The computer readable medium of claim 13 , further including instructions to produce confidence levels of actions in the action list; and to select an action based on the action list confidence levels.

16. The computer readable medium of claim 11 , wherein the entry selected is one of a verb and an adverb-verb combination.

17. The computer readable medium of claim 11 , wherein the entry selected is one of a noun or an adjective-noun combination.

18. The computer readable medium of claim 11 , further comprising instruction to utilize a synonym table to select one of an action and an object.
