4. A method comprising: parsing, by a hardware processor, a spoken statement to detect a plurality of words in the spoken statement; generating, by the hardware processor, a parse tree based on the detected plurality of words, the parse tree identifies at least one of a clause, phrase, subject, verb, and object in the spoken statement: determining, by the hardware processor, based on the parse tree, a plurality of potential services to invoke to respond to the spoken statement by comparing the at least one clause, phrase, subject, verb, and object to a stored ontology to extract a concept from the parse tree; calculating, by the hardware processor, a confidence score for each potential service of the plurality of potential services by determining a shortest distance between a first node and a second node for each potential service, the first node representing the plurality of words, the second node representing that potential service, wherein each confidence score indicates a likelihood that a potential service is a service requested by the spoken statement; receiving, for each potential service of the plurality of potential services, a parameter used during execution of that potential service; updating, by the hardware processor, the confidence score for each potential service of the plurality of potential services based on a determination of whether the spoken statement includes a value for the parameter used during execution of that potential service so as to reduce a number of questions that a caller associated with the spoken statement answers before the language processor determines a service to invoke to respond to the caller; issuing, by the hardware processor, a command to invoke a potential service of the plurality of potential services with confidence score based on the shortest distance; communicating, by the hardware processor, an audible question in response to a determination that two or more potential services of the plurality of potential services have equivalent confidence scores; and communicating, by the hardware processor, an audible request for a value of a received parameter.

The method of claim 4 , wherein calculating the confidence score for each potential service comprises comparing the parse tree against a plurality of parse trees.
