12. The method of claim 1 , further comprising displaying a menu of available subsequent command items from the subsequent command level in the vocabulary of command items.

13. The method of claim 12 , wherein the menu of available command items is no longer displayed upon determining that a subsequent vocal utterance from the plurality of vocal utterances corresponds to a subsequent command item from the subsequent command level in the vocabulary of command items.

14. The method of claim 13 , wherein the subsequent command item from the subsequent command level in the vocabulary of command items that corresponds to the subsequent vocal utterance from the plurality of vocal utterances continues to be displayed.

15. The method of claim 12 , wherein the menu is a branching menu.

16. The method of claim 1 , wherein if the subsequent vocal utterance corresponds to the associated subsequent command item from the subsequent command level in the vocabulary of command items, determining whether the subsequent command item from the subsequent command level is associated with another command item from another command level in the vocabulary of command items; and

if the subsequent command item from the subsequent command level is associated with another command item from another command level in the vocabulary of command items, determining whether another vocal utterance from the plurality of vocal utterances corresponds to the associated another command item from the another command level in the vocabulary of command items.

17. The method of claim 16 , wherein if the another vocal utterance corresponds to the associated another command item from the another command level in the vocabulary of command items, performing an action that corresponds to the complete and uninterrupted command.

18. A machine-readable medium having embodied thereon a program, the program being executable by a machine to perform a method for controlling at least one character in a visually dynamic and interactive game environment, the method comprising:

receiving a complete and uninterrupted command from a user, the complete and uninterrupted command comprising a plurality of vocal utterances;

determining whether a first vocal utterance from the plurality of vocal utterances corresponds to a first command item from a first command level in a vocabulary of command items;

if the first vocal utterance corresponds to a first command item from the first command level in the vocabulary of command items, determining whether the first command item from the first command level is associated with a subsequent command item from a subsequent command level in the vocabulary of command items; and

if the first command item from the first command level is associated with a subsequent command item from a subsequent command level in the vocabulary of command items, determining whether a subsequent vocal utterance from the plurality of vocal utterances corresponds to the associated subsequent command item from the subsequent command level in the vocabulary of command items, wherein if the subsequent vocal utterance corresponds to the associated subsequent command item from the subsequent command level in the vocabulary of command items, performing an action that corresponds to the complete and uninterrupted command.

19. The machine-readable medium of claim 18 , further comprising displaying a menu of available subsequent command items from the subsequent command level in the vocabulary of command items.

20. The method of claim 19 , wherein the menu of available command items is no longer displayed upon determining that a subsequent vocal utterance from the plurality of vocal utterances corresponds to a subsequent command item from the subsequent command level in the vocabulary of command items.

21. The method of claim 20 , wherein the subsequent command item from the subsequent command level in the vocabulary of command items that corresponds to the subsequent vocal utterance from the plurality of vocal utterances continues to be displayed.

22. A system for controlling at least one character in a visually dynamic and interactive game environment, the system comprising:

a microphone configured to receive a complete and uninterrupted command from a user, the complete and uninterrupted command comprising a plurality of vocal utterances;

a speech recognition module coupled to the microphone, the speech recognition module the speech recognition module configured to:

determine whether a first vocal utterance from the plurality of vocal utterances corresponds to a first command item from a first command level in a vocabulary of command items;

if the first vocal utterance corresponds to a first command item from the first command level in the vocabulary of command items, determine whether the first command item from the first command level is associated with a subsequent command item from a subsequent command level in the vocabulary of command items;

if the first command item from the first command level is associated with a subsequent command item from a subsequent command level in the vocabulary of command items, determine whether a subsequent vocal utterance from the plurality of vocal utterances corresponds to the associated subsequent command item from the subsequent command level in the vocabulary of command items; and

if the subsequent vocal utterance corresponds to the associated subsequent command item from the subsequent command level in the vocabulary of command items, generate a notification for game software corresponding to the visually dynamic and interactive game environment to provide instructions causing the at least one character to perform an action that corresponds to the complete and uninterrupted command.

23. The system of claim 22 , further comprising a controller device configured to provide instructions for controlling an action of the at least one character, the action corresponding to the instruction.
