Method and system for automatic detecting morphemes in a task classification system using lattices
First Claim
1. A method of task classification which operates on one or more task objectives of a user, comprising:
- forming a lattice of phone strings representing morphemes in a user'"'"'s input communication, the lattice representing a distribution over the phone strings;
detecting morphemes in the user'"'"'s input communication using the formed lattice; and
making task-type classification decisions based on the detected morphemes in the user'"'"'s input communication.

Abstract
The invention concerns a method and system for detecting morphemes in a user'"'"'s communication. The method may include recognizing a lattice of phone strings from the user'"'"'s input communication, the lattice representing a distribution over the phone strings, and detecting morphemes in the user'"'"'s input communication using the lattice. The morphemes may be acoustic and/or non-acoustic. The morphemes may represent any unit or sub-unit of communication including phones, diphones, phone-phrases, syllables, grammars, words, gestures, tablet strokes, body movements, mouse clicks, etc. The training speech may be verbal, non-verbal, a combination of verbal and non-verbal, or multimodal.
