A methodology for automated task selection is provided, where the selected task is identified in natural speech of a user making such a selection. A set of meaningful phrases are determined by a grammatical inference algorithm which operates on a predetermined corpus of speech utterances, each such utterance being associated with a specific task objective, and wherein each utterance is marked with its associated task objective. Each meaningful phrase developed by the grammatical inference algorithm can be characterized as having both a Mutual Information value and a Salience value (relative to an associated task objective) above a predetermined threshold.
