Abstract

A computer-implemented method and system for processing requests voiced by a user. User speech input is received that contains words from the user that are directed to at least one concept. The user speech input contains a request for a service to be performed. Speech recognition of the user speech input generates recognized words. The concept of the user speech input is determined by applying fuzzy logic rules to the recognized words. The fuzzy logic rules define non-crisp relationships among predetermined concepts. The user'"'"'s request is processed based upon the determined concept of the user speech input.

Claims

1. A computer-implemented method for processing requests voiced by a user, comprising the steps of:

receiving user speech input that contains words from the user that are directed to at least one concept, said user speech input containing a request for a service to be performed;

performing speech recognition of the user speech input to generate recognized words;

determining the concept of the user speech input by applying fuzzy logic rules to the recognized words, said fuzzy logic rules defining non-crisp relationships among predetermined concepts; and

processing the user'"'"'s request based upon the determined concept of the user speech input.
