What is the Topics field under ViaVoice Options, User tab?
A Topic is like a new type of “mini-vocabulary”. Each topic will consist of words and pronunciations covering a specific subject. It is different from a Vocabulary in that it can be active along with the General Dictation Vocabulary installed in the system. In addition, you can have a number of topics active at the same time whereas before you could only have one specialized Vocabulary available at a time. You can add new Topics or Vocabularies with the Vocabulary and Topic Installer. The Vocabulary and Topic Installer is available in ViaVoice Pro and Advanced Editions Only.
