1. An automated response tool comprising: a receiver configured to receive a call and a spoken statement from the received call; a language processor configured to: detect a plurality of words in the spoken statement; generate a parse tree based on the detected plurality of words; determine, based on the parse tree, a plurality of services to invoke in response to the spoken statement; calculate a confidence score for each service of the determined plurality of services based on the parse tree 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, each confidence score indicating a likelihood that a potential service is a service requested by the spoken statement; determine, for each service of the plurality of services, a parameter used during execution of that service; determine, for each determined parameter for each service of the plurality of services, based on the parse tree, whether the spoken statement comprises a value for that determined parameter; eliminate a service of the plurality of services in response to a determination that the spoken statement does not comprise a value for the determined parameter of the eliminated service; determine, based on the parse tree, to invoke a service of the plurality of services with the highest confidence score based on the shortest distance in response to the spoken statement; determine a parameter used during execution of the determined service; and determine, based on the parse tree, a value of the determined parameter; a service invoker configured to issue a command to invoke a service of the plurality of services with the highest confidence score based on the shortest distance, wherein the command comprises the determined value of the determined parameter; and a transmitter configured to communicate an audible question in response to a determination that two or more services of the plurality of services have equivalent confidence scores.
