Generating reference variations

1. A system, comprising:

a logic device configured to:

receive a telephone number provided to a caller by an operator in response to voice input from the caller,

identify a listing associated with the telephone number,

generate a variation associated with at least a portion of the listing based on the voice input, the variation comprising an alternative way to identify at least the portion of the listing;

a memory configured to store a plurality of audio files corresponding to voice inputs provided by callers and which were forwarded to operators.

2. The system of claim 1 , wherein the logic device is further configured to:

at least one of generate or modify a grammar associated with performing speech recognition based on the variation.

3. The system of claim 2 , wherein the logic device is further configured to:

apply the variation to a portion of a plurality of listings.

4. The system of claim 1 , wherein the logic device is further configured to:

access the memory to identify a first audio file corresponding to a first voice input,

perform speech recognition on the first audio file, and

generate the variation using output from the speech recognition.

5. The system of claim 1 , wherein the logic device is further configured to:

determine a number of times a first voice input was received from callers, and

modify a grammar associated with performing speech recognition after the first voice input was received from callers a predetermined number of times.

6. A method, comprising:

receiving information provided to a caller in response to an utterance from the caller, the utterance being associated with identifying an item of interest; and

generating a reference variation associated with identifying the item of interest based on the utterance;

determining a number of times a given utterance was received from callers, and

modifying a grammar associated with performing speech recognition after the first voice input has been received from callers a predetermined number of times.

7. The method of claim 6 , further comprising:

generating a rule associated with performing speech recognition based on the reference variation.

8. The method of claim 7 , further comprising:

using the rule for identifying a plurality of items of interest.

9. A speech recognition system, comprising:

logic configured to:

receive information provided by a human operator to a caller in response to an utterance from a caller,

identify an item of interest associated with the information provided by the operator, and

generate a variation of at least one word associated with the item of interest based on the utterance;

store audio files corresponding to voice inputs provided by callers which have been forwarded to the human operator.

10. The speech recognition system of claim 9 , wherein the logic is further configured to:

generate a grammar associated with performing speech recognition based on the variation.

11. The speech recognition system of claim 9 , wherein the information provided by the human operator comprises a business name.

12. The speech recognition system of claim 9 , wherein the logic device is further configured to:

identify a first audio file corresponding to a first voice input,

perform speech recognition on the first audio file, and

wherein, the variation is generate from the speech recognition.

13. The speech recognition system of claim 9 , wherein the logic device is further configured to:

determine a number of times a given voice input has been received from callers, and

modify a grammar associated with performing speech recognition after the given voice input was received from callers a predetermined number of times.

14. A system, comprising:

a logic device configured to:

receive a telephone number provided to a caller by an operator in response to voice input from the caller,

identify a listing associated with the telephone number, and

generate a variation associated with at least a portion of the listing based on the voice input, the variation comprising an alternative way to at least the portion of the listing;

determine a number of times a given voice input was received from callers, and

modify a grammar used for performing speech recognition after the given voice input has been received from callers a predetermined number of times.

15. The system of claim 14 , wherein the logic device is further configured to:

generate a grammar associated with performing speech recognition based on the variation.

16. The system of claim 14 , wherein the logic device is further configured to:

modify a grammar associated with performing speech recognition based on the variation.

17. The system of claim 14 , wherein the logic device is further configured to:

apply the variation to a portion of a plurality of listings.

18. The system of claim 14 , wherein, the logic device further stores a plurality of audio files corresponding to voice inputs provided by callers and which have been forwarded to operators.

19. The system of claim 14 , wherein the logic device is further configured to:

identify a first audio file corresponding to a first voice input,

perform speech recognition on the first audio file, and

generate the variation using output from the speech recognition.

20. The system of claim 14 , wherein, the listing provided to the caller includes a business name.
