Abstract

In a speech recognition system, a method of providing a concise form of a natural command can include receiving a user specified command and identifying all functionally equivalent natural command forms of the user specified command from a natural command grammar. The length of each functionally equivalent natural command form can be determined. The method also can include presenting a selected one of the functionally equivalent natural command forms having the shortest length to the user.

Claims

1. In a speech recognition system, a method of providing a concise form of a natural command, said method comprising:

receiving a user specified command;

identifying all functionally equivalent natural command forms of said user specified command from a natural command grammar;

determining a length of each said functionally equivalent natural command form; and

presenting a selected one of said functionally equivalent natural command forms having the shortest length to said user.

2. The method of claim 1, said presenting step comprising:

presenting a selected plurality of functionally equivalent natural command forms to said user, each one of said selected plurality of functionally equivalent natural command forms having a shortest and equivalent length.

3. The method of claim 1, said presenting step comprising:

presenting a selected one from a plurality of functionally equivalent natural command forms to said user, each one of said plurality of functionally equivalent natural command forms having a shortest and equivalent length.

4. The method of claim 1, wherein if said user specified command is a natural command, said functionally equivalent natural command forms include said received user specified natural command form.

5. In a speech recognition system, a method of providing a concise form of a natural command, said method comprising:

receiving a user specified command;

identifying all functionally equivalent natural command forms of said user specified command from a natural command grammar;

determining a length of each said functionally equivalent natural command form; and

presenting a selected at least one of said functionally equivalent natural command forms having the shortest length to said user.

6. A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:

receiving a user specified command;

identifying all functionally equivalent natural command forms of said user specified command from a natural command grammar;

determining a length of each said functionally equivalent natural command form; and

presenting a selected one of said functionally equivalent natural command forms having the shortest length to said user.

7. The machine readable storage of claim 6, said presenting step comprising:

presenting a selected plurality of functionally equivalent natural command forms to said user, each one of said selected plurality of functionally equivalent natural command forms having a shortest and equivalent length.

8. The machine readable storage of claim 6, said presenting step comprising:

presenting a selected one from a plurality of functionally equivalent natural command forms to said user, each one of said plurality of functionally equivalent natural command forms having a shortest and equivalent length.

9. The machine readable storage of claim 6, wherein if said user specified command is a natural command, said functionally equivalent natural command forms include said received user specified natural command form.

10. A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:

receiving a user specified command;

identifying all functionally equivalent natural command forms of said user specified command from a natural command grammar;

determining a length of each said functionally equivalent natural command form; and

presenting a selected at least one of said functionally equivalent natural command forms having the shortest length to said user.
