Abstract

A grammar update method for storing grammar data for speech interaction used for recognizing speech data and newly recognizing the speech data without using the grammar data, includes determining whether or not a new-recognition result in the newly-recognizing operation can be accepted, and in the case where the new-recognition result cannot be accepted, specifying a portion to be added and updated from the stored grammar data, thereby adding and updating the grammar data.

Claims

1. A grammar update system, comprising:

an update original grammar recording part for storing grammar data for speech interaction used for recognizing speech data;

a speech newly-recognizing part for newly recognizing the speech data without using the grammar data;

a new-recognition result determining part for determining whether or not a new-recognition result in the speech newly-recognizing part is acceptable using the grammar data; and

a grammar adding and updating part for, in a case where it is determined that the new-recognition result is unacceptable using the grammar data in the new-recognition result determining part, specifying a portion to be added and updated from the grammar data stored in the update original grammar recording part, and adding the portion to be added and updated to the grammar data so as to update the grammar data.

3. A grammar update system according to claim 1, wherein the grammar adding and updating part is capable of setting restriction matter regarding an update of the grammar data.

5. A grammar update system according to claim 1, comprising:

an update information presenting part for presenting the added and updated grammar data or an update portion in the grammar data; and

an update instruction input part for confirming whether or not an update operation is executed on a basis of the presented update portion of the grammar data.

2. A grammar update system, comprising:

a log data recording part for storing at least speech data and a speech recognition result as log data;

an update original grammar recording part for storing grammar data for speech interaction used for recognizing the speech data;

a log obtaining part for obtaining the speech data stored in the log data recording part;

a speech newly-recognizing part for newly recognizing the speech data obtained in the log obtaining part without using the grammar data;

a new-recognition result determining part for determining whether or not a new-recognition result in the speech newly-recognizing part is acceptable using the grammar data; and

a grammar adding and updating part for, in a case where it is determined that the new-recognition result is unacceptable using the grammar data in the new-recognition result determining part, specifying a portion to be added and updated from the grammar data stored in the update original grammar recording part, and adding the portion to be added and updated to the grammar data so as to update the grammar data.

4. A grammar update system according to claim 2, wherein the grammar adding and updating part is capable of setting restriction matter regarding an update of the grammar data.

6. A grammar update system according to claim 2, comprising:

an update information presenting part for presenting the added and updated grammar data or an update portion in the grammar data; and

an update instruction input part for confirming whether or not an update operation is executed on a basis of the presented update portion of the grammar data.

7. A grammar update method comprising the operations of:

storing grammar data for speech interaction used for recognizing speech data;

newly recognizing the speech data without using the grammar data;

determining whether or not a new-recognition result in the newly-recognizing operation is acceptable using the grammar data; and

in a case where it is determined that the new-recognition result is unacceptable using the grammar data in the determining operation, specifying a portion to be added and updated from the stored grammar data, and adding the portion to be added and updated to the grammar data so as to update the grammar data.

8. A grammar update method comprising the operations of:

storing at least speech data and speech recognition result as log data, storing grammar data for speech interaction used for recognizing the speech data, and obtaining the stored speech data;

newly recognizing the obtained speech data without using the grammar data;

determining whether or not a new-recognition result in the newly-recognizing operation is acceptable using the grammar data; and

in a case where it is determined that the new-recognition result is unacceptable using the grammar data in the determining operation, specifying a portion to be added and updated from the stored grammar data, and adding the portion to be added and updated to the grammar data so as to update the grammar data.

9. A recording medium storing a computer-executable program for realizing a grammar update method,

the method comprising the operations of:

storing grammar data for speech interaction used for recognizing speech data and newly recognizing the speech data without using the grammar data;

determining whether or not a new-recognition result in the newly-recognizing operation is acceptable using the grammar data; and

in a case where it is determined that the new-recognition result is unacceptable using the grammar data in the determining operation, specifying a portion to be added and updated from the stored grammar data, and adding the portion to be added and updated to the grammar data so as to update the grammar data.

10. A recording medium storing a computer-executable program for realizing a grammar update method,

the method comprising the operations of:

storing at least speech data and speech recognition result as log data, storing grammar data for speech interaction used for recognizing the speech data, and obtaining the stored speech data;

newly recognizing the obtained speech data without using the grammar data;

determining whether or not a new-recognition result in the newly-recognizing operation is acceptable using the grammar data; and

in a case where it is determined that the new-recognition result is unacceptable using the grammar data in the determining operation, specifying a portion to be added and updated from the stored grammar data, and adding the portion to be added and updated to the grammar data so as to update the grammar data.
