1. A language processor comprising: a parser configured to: parse a spoken statement to detect a plurality of words in the spoken statement; and generate a parse tree based on the detected plurality of words; an invoker configured to: determine, based on the parse tree, a plurality of potential services to invoke to respond to the spoken statement; calculate 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; receive, for each potential service of the plurality of potential services, a parameter used during execution of that potential service; update 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; issue a command to invoke a potential service of the plurality of potential services with the highest confidence score based on the shortest distance; and a transmitter configured to: communicate 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 communicate an audible request for a value of a received parameter.
