You decide which language database Blueworx Voice Response copies to create the new language database. When the system is installed, the only database available is the database for U.S. English. When you have defined more languages, however, you can copy any one of them. You do not have to copy English.
For example, suppose you need two new languages: German and Swiss German. To create the German database, you must copy the U.S. English database. To create the Swiss German database, you can copy either the U.S. English database or the German database.
