An additional language name U.S. English TDD is defined to support applications that interact with Telecommunications Devices for the Deaf. If you have installed the optional Telecommunications Devices for the Deaf package, you must import the supplied voice segments and system prompts. These segments and prompts provide TDD equivalents for the base system prompts and segments.
To add the TDD languages, follow the instructions that are given in Defining additional languages. Choose a Language Type of Voice Only, and a New Language Name of U.S. English TDD. Do not copy any voice information from other languages, because this information is not needed and uses space in the voice database.
When you have saved the new language, import it (as described in the Blueworx Voice Response for AIX: Designing and Managing State Table Applications information) to add the base system prompts and segments for the TDD language. The import file is /usr/lpp/dirTalk/sw/samples/TDD.imp.
You can now run the predefined applications for a TDD caller, simply by creating and using an application profile that specifies the U.S. English TDD language. Blueworx Voice Response for AIX: Designing and Managing State Table Applications information describes how you can create versions of your own applications for TDD callers.
