USER DIRECTED ADAPTATION OF SPOKEN LANGUAGE GRAMMER
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.
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.
