Patent Images
1. A method comprising:
- receiving speech from a user;
selecting candidate morphemes from the speech;
forming, via a processor, a lattice, based, at least in part, on the candidate morphemes and stored morphemes;
determining a task objective of the speech, based at least in part on the lattice; and
routing the user according to the task objective.

Abstract
In an embodiment, a lattice of phone strings in an input communication of a user may be recognized, wherein the lattice may represent a distribution over the phone strings. Morphemes in the input communication of the user may be detected using the recognized lattice. Task-type classification decisions may be made based on the detected morphemes in the input communication of the user.
