- LVParseTree GetParseTree(int VoiceChannel, int index)
The audio channel containing the input audio
It is possible to have more than one parse tree for an utterance (for instance if the grammar is ambiguous); this is the index of the tree
The return type is a parse tree object.
A parse tree and the parse string returned are logically the same. However, an LVParseTree object makes it easy to search the parse tree for useful information.
The LVParseTree object can be manipulated using the methods described in the LVParseTree C++ API.
