receive initial speech input data before presenting information associated with each node in the second group; and

determine that the initial speech input data matches speech input data associated with a child node of the current node.

11. The computing device of claim 1 , wherein program instructions executable by the at least one processor to move a selection of nodes from the first group to the second group comprise program instructions executable by the at least one processor to determine the selection of nodes from the first group to the second group based on a frequency of speech inputs associated with nodes in the first group of nodes.

12. The computing device of claim 1 , further comprising a head-mountable display (HMD), wherein the program instructions executable by the at least one processor to present information associated with each node in the second group comprise instructions executable by the at least one processor to display the nodes in the second group on a graphical display of the HMD.

13. A non-transitory computer-readable medium having stored thereon instructions executable by a computing device to cause the computing device to cause the computing device to perform functions comprising:

(a) designating a first node of a tree as a current node, wherein each node in the tree is associated with a speech input, wherein the first node comprises one or more child nodes;

(b) removing all nodes from a first group of nodes;

(c) copying each child node of the current node to the first group;

(d) removing all nodes from a second group of nodes;

(e) moving a selection of nodes from the first group to the second group; and

(f) presenting information associated with each node in the second group.

14. The non-transitory computer-readable medium of claim 13 , wherein the instructions are further executable to cause the computing device to perform functions comprising:

receiving an arbitrary speech input;

determining that the arbitrary speech input corresponds to speech input data associated with a second node that is a child node of the current node; and

adding the speech input data associated with the second node to an input-grammar segment.

15. The non-transitory computer-readable medium of claim 14 , wherein the instructions are further executable to cause the computing device to perform functions comprising:

determining that the second node does not comprise one or more child nodes, and

executing a function associated with the second node.

16. The non-transitory computer-readable medium of claim 13 , wherein the instructions are further executable to cause the computing device to:

receiving an arbitrary speech input;

determining that the arbitrary speech input does not correspond to speech input data associated with a child node of the current node; and

performing (d)-(g).

17. A computer-implemented method comprising:

(a) designating a first node of a tree as a current node, wherein each node in the tree is associated with a speech input, wherein the first node comprises one or more child nodes;
