The engine is not outdated. The voice config file might handled it differently. I know for sure that NNG passed street name with special nuance directive (to be handled after the appropriate preprocessing) One of the thing that it preprocessed special for is US roadname; there is a "catch all" that handle anything else (but...this routine doesn't seem to be called, very odd) Stay tune for my analysis later on tonight. One more thing make absolutely sure it is using the correct voice config (remove everything except it under the content/voice directory)
