A method for providing a voice application includes executing control flow logic modeling a dialog flow with a user via a voice browser. The control flow logic produces a disambiguation requirement. A disambiguation module is initiated and a set of at least two candidates and partitioning criteria is sent from the control flow logic to the module. Attributes of the candidates are analyzed to determine a partitioning score for each attribute indicative of ability to distinguish between candidates based on the partitioning criteria. The attributes are sorted based on the partitioning scores. The user is queried based on a top-sorted attribute and results of the query are used to reduce the set of candidates. The steps of analyzing, sorting, and querying are repeated until the set of candidates is reduced to a single candidate. The single candidate is returned to the control flow logic for continued execution.
