An article has posted over at IBM developerWorks titled Create automated verbal conversation annotations for phone numbers, acronyms, and other spoken words:

"Use the open source Sphinx-4 speech-recognition package to capture letters and numbers from spoken conversations in near real time to create notes. Employ a custom Sphinx-4 dictionary file to extract likely matches to spoken letters and numbers. Process the text for higher order values, such as phone numbers and acronyms, and create a meeting annotator through search-engine lookups and local databases."

As usual with IBM developerWorks articles, there is a feedback form at the bottom.
