A computerized method is provided for electronically directing a call to a
class, such that an utterance spoken by a speaker and received by a
call-routing system is classified by the call-routing system as being
associated with the class, such that the call-routing system includes a
speech-recognition module, a feature-extraction module, and a
classification module. The method includes extracting features from
recognized speech; weighting elements of a feature vector with respective
speech-recognition scores, wherein each weighting element is associated
with one of the features; ranking classes to which the features are
associated; and electronically directing the call to a highest-ranking
class.
