On AIX, for U.S. English (en_US) and U.K. English (en_GB), you can use the System voice segments on your base Blueworx Voice Response system instead of the new voice segments. This is an option you can select when you install the language.
For all other languages on AIX, you cannot use existing System voice segments, because the voice segment names used by the Java language mappers are different from those used by Blueworx Voice Response for AIX . You must either use the supplied ones, or record new System voice segments.
