2. An automated task classification system that detects morphemes using lattices and operates on one or more task objectives of a user, comprising: a recognizer that forms a lattice of phone strings representing morphemes in a user's input communication, the lattice representing a distribution over the phone strings; a morpheme detector that detects morphemes in the user's input communication using the formed lattice; and a task classification processor that makes task-type classification decisions based on the detected morphemes in the user's input communication.
