11. A system for managing speech data in a computing system of an aircraft, comprising: an information datastore that stores a definition file that is associated with an aircraft related application, wherein the definition file includes a tree structure including a plurality of data structures that define features of a displayed interface associated with the aircraft related application, each data structure including a speech tag that comprises a string of characters that is associated with a name, a label, or function of the feature; and a computer module that receives speech data, that hierarchically searches, by a processor, the data structures of the tree structure for a speech tag that matches the text of the speech data, wherein the hierarchical search comprises evaluating a state of the features associated with the data structures for visibility, and that communicates data to the aircraft related application or generates display data based on an action associated with the speech tag.
