Vestec is working on MRCP (Media Resource Control Protocol) support, non-English acoustic models, and large vocabulary engines. In our opinion, the overwhelming majority of speech recognition opportunities in North America do not require MRCP for platform integration, non-English acoustic models, or more than 500 vocabulary items per recognition.
