Abstract

An information processing apparatus inputs a document having a plurality of input fields, and displays it using a display control item. The apparatus then determines whether or not one of the plurality of input fields is designated by the user. Specific grammar corresponding to the designated input field is selected from a grammar holding unit for holding a plurality of types of grammar, and the selected grammar is used in a speech recognition process.

Claims

1. An information processing apparatus comprising:

display control means for controlling a display to display a plurality of input fields;

determining means for determining whether or not one of the plurality of input fields is designated by a user;

selection means for selecting grammar corresponding to the designated input field determined by said determining means;

speech determining means for determining the inputting of input speech after the determining by said determining means that one of the plurality of input fields is designated by a user, and the selection by said selection means of a grammar corresponding to the designated input field; and

speech recognition means for recognizing the input speech determined to be input by said speech determining means by utilizing the grammar selected by said selection means.

2. The apparatus according to claim 1, wherein said display control means controls a display of a recognition result of said speech recognition means in the designated input field.

3. An information processing method comprising:

a display control step of controlling a display to display a plurality of input fields;

a determining step of determining whether or not one of the plurality of input fields is designated by a user;

a selection step of selecting grammar corresponding to the designated input field determined in said determining step;

a speech determining step of determining the inputting of input speech after the determining by said determining step that one of the plurality of input fields is designated by a user, and the selection by said selection step of a grammar corresponding to the designated input field; and

a speech recognition step of recognizing the input speech determined to be input by said speech determining step by utilizing the grammar selected in said selection step.

4. The method according to claim 3, wherein said display control step controls a display of a recognition result of said speech recognition step in the designated input field.

5. A control program embodied in a computer-readable medium for making a computer implement an information process, comprising:

code of a display control step of controlling a display to display a plurality of input fields;

code of a determining step of determining whether or not one of the plurality of input fields is designated by a user;

code of a selection step of selecting grammar corresponding to the designated input field determined in said determining step;

code of a speech determining step of determining the inputting of input speech after the determining by said determining step that one of the plurality of input fields is designated by a user, and the selection by said selection step of a grammar corresponding to the designated input field; and

code of a speech recognition step of recognizing the input speech determined to be input by said speech determining step by utilizing the grammar selected in said selection step.

6. The control program according to claim 5, wherein said display control step controls a display of a recognition result of said speech recognition step in the designated input field.

7. An information processing apparatus comprising:

display control means for controlling a display to display a plurality of input fields;

detecting means for detecting whether or not a mouse pointer is staying on one of the plurality of input fields;

selection means for, when detected by said detecting means that the mouse pointer is staying on one of the plurality of input fields, selecting grammar corresponding to the input field;

speech receiving means for receiving input speech while the mouse pointer is staying on the input field; and

speech recognition means for recognizing input speech received by said speech receiving means by utilizing the grammar selected by said selection means.

8. An information processing method comprising:

a display control step of controlling a display to display a plurality of input fields;

a detecting step of detecting whether or not a mouse pointer is staying on one of the plurality of input fields;

a selection step of, when detected in said detecting step that the mouse pointer is staying on one of the plurality of input fields, selecting grammar corresponding to the input field;

a speech receiving step of receiving input speech while the mouse pointer is staying on the input field; and

a speech recognition step of recognizing input speech received in said speech receiving step by utilizing the grammar selected in said selection step.

9. A control program embodied in a computer-readable medium for making a computer implement an information process, comprising:

code of a display control step of controlling a display to display a plurality of input fields;

code of a detecting step of detecting whether or not a mouse pointer is staying on one of the plurality of input fields;

code of a selection step of, when detected in said detecting step that the mouse pointer is staying on one of the plurality of input fields, selecting grammar corresponding to the input field;

code of a speech receiving step of receiving input speech while the mouse pointer is staying on the input field; and

code of a speech recognition step of recognizing input speech received in said speech receiving step by utilizing the grammar selected in said selection step.

10. An information processing apparatus comprising:

display control means for controlling a display to display at least one of a plurality of input fields, the display being configured to display less than all of the plurality of input fields simultaneously;

selection means for selecting a specific grammar corresponding to an input field displayed on the display to be used for speech recognition of speech inputted for the displayed input field; and

speech recognition means for recognizing input speech input for the displayed input field by utilizing the grammar selected by said selection means without utilizing grammar corresponding to input fields not displayed on the display.

11. An information processing method comprising:

a display control step of controlling a display to display at least one of a plurality of input fields, the display being configured to display less than all of the plurality of input fields simultaneously;

a selection step of selecting a specific grammar corresponding to an input field being displayed on the display to be used for speech recognition of speech inputted for the displayed input field; and

a speech recognition step of recognizing input speech input for the displayed input field by utilizing the grammar selected in said selection step without utilizing grammar corresponding to input fields not displayed on the display.

12. A control program embodied in a computer-readable medium for making a computer implement an information process, comprising:

code of a display control step of controlling a display to display at least one of a plurality of input fields, the display being configured to display less than all of the plurality of input fields simultaneously;

code of a selection step of selecting a specific grammar corresponding to an input field being displayed on the display to be used for speech recognition of speech inputted for a displayed input field; and

code of a speech recognition step of recognizing input speech input for the displayed input field by utilizing the grammar selected in said selection step without utilizing grammar corresponding to input fields not displayed on the display.
