Just to bring this new Working Draft to the attention of Wordnet/RDF

Pronunciation Lexicon Specification (PLS) Version 1.0 Requirements
The W3C Voice Browser Working Group aims to develop specifications to
enable access to the Web using spoken interaction. This document is part
of a set of requirements studies for voice browsers, and provides
details of the requirements for markup used for specifying application
specific pronunciation lexicons.

Application specific pronunciation lexicons are required in many
situations where the default lexicon supplied with a speech recognition
or speech synthesis processor does not cover the vocabulary of the
application. A pronunciation lexicon is a collection of words or phrases
together with their pronunciations specified using an appropriate
pronunciation alphabet.

In passing I note a 'should have' requirement we ought to watch:
3.8 Metadata information (should have)

The pronunciation lexicon markup should provide a mechanism for
specifying metadata within pronunciation lexicon documents. This
metadata can contain information about the document itself rather than
document content. For example: record the purpose of the lexicon
document, the author, etc.

For more on W3C's work in this area, see http://www.w3.org/TR/voice-intro/
"Introduction and Overview of W3C Speech Interface Framework" (from
2000) or the more actively maintained Voice Browser home page,

If this stuff engages your interest, then http://www.w3.org/TR/voicexml21/
"Voice Extensible Markup Language (VoiceXML) 2.1" is probably a good
thing to review to get a sense of how those groups are addressing this
