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.
13. The automated task classification system of claim 2 , wherein the system operates in conjunction with one or more communication networks, the one or more communication networks including at least one of a telephone network, the Internet, an intranet, Cable TV network, a local area network (LAN), and a wireless communication network.
