1. XML Output for Sphinx
Motivation: applications may be able to make use of richer information from sphinx including n-best lists, the word lattice, and other features. An xml dtd format will be standard, and easy to parse, express, and modify.

2. Proposed DTD http://www.cs.cmu.edu/~tkharris/usi/utterance-0.1.dtd
Sphinx produces utterances, each utterance is an xml document that conforms to the DTD
An utterance is an n-best list or word-lattice or both
An n-best list is a list of lists of words
Each list and the words may have features
The DTD desperately needs review

3. Issues Is the motivation justified?
Computational/Network impact too much?
API’s are needed to parse XML
Need to get requirements/observations from Sphinx customers
