Abstract

A method and system for interacting with a speech recognition system. A lattice of candidate words is displayed. The lattice of candidate words may include the output of a speech recognizer. Candidate words representing temporally serial utterances may be directly joined in the lattice. A path through the lattice represents a selection of one or more candidate words interpreting one or more corresponding utterances. An interface allows a user to select a path in the lattice. A selection of the path in the lattice may be received and the selection may be stored. The selection may be provided as positive feedback to the speech recognizer.

Claims

1. A method for interacting with a speech recognition system, the method comprising:

displaying a lattice of candidate words;

receiving a selection of a path in the lattice, the path comprising at least one of the candidate words; and

storing the selection.

2. The method of claim 1, wherein the lattice of candidate words comprises output of a speech recognizer.

3. The method of claim 2, wherein the lattice of candidate words comprises a first candidate word corresponding to a first utterance received by the speech recognizer, the first candidate word being joined in the lattice to a second candidate word and to a third candidate word, the second and third candidate words each corresponding to a second utterance received by the speech recognizer.

4. The method of claim 3, wherein selected path comprises the second candidate word, and further comprising clearing the third candidate word from the lattice.

5. The method of claim 2, further comprising providing the selection as positive feedback to the speech recognizer.

6. The method of claim 2, further comprising playing the recognizer input corresponding to the path.

7. The method of claim 1, further comprising providing an audible representation of the selection.

8. The method of claim 7, further comprising receiving verification of the selected path.

9. The method of claim 1, wherein storing comprises storing the selected path in a transcript.

10. The method of claim 1, wherein the selection comprises a movement of a user-input device to a plurality of positions, each position corresponding to the path in the lattice.

11. The method of claim 1, further comprising receiving the lattice in an instant messaging protocol.

12. A speech recognition system comprising:

a user interface adapted to display a graphical representation of a lattice of candidate words and to receive a selection of a path in the lattice; and

a datastore adapted to store the selection.

13. The system of claim 12, wherein the lattice of candidate words comprises output from a speech recognizer.

14. The system of claim 13, wherein the lattice of candidate words comprises a first candidate word corresponding to a first utterance received by the speech recognizer, the first candidate word being joined in the lattice to a second candidate word and to a third candidate word, the second and third candidate words each corresponding to a second utterance received by the speech recognizer.

15. The system of claim 12, further comprising a user-input device in communication with the processor, wherein the selection of a path comprises movement of the user-input device to a plurality of positions, each position corresponding to the path in the lattice.

16. The system of claim 12, further comprising an output that provides the selection to a text-to-speech engine.

17. A computer readable storage medium for interacting with a speech recognition system, the speech recognition system receiving an utterance, the computer readable storage medium including computer executable instructions to perform the acts comprising:

displaying a lattice of candidate words;

receiving a selection of a path in the lattice, the path comprising at least one of the candidate words; and

providing the path for confirmation that the path corresponds to the utterance.

18. The computer readable storage medium of claim 17, wherein the path comprises at least a candidate word and providing the path for confirmation comprises providing the candidate word to a text-to-speech engine.

19. The computer readable storage medium of claim 17, wherein the computer executable instructions perform the acts further comprising:

receiving the lattice in an instant messaging protocol.

20. The computer readable storage medium of claim 17, wherein the computer executable instructions perform the acts further comprising:

providing the selection as positive feedback to the speech recognition system.
