Dialog Designer supports language implementation on four levels:
Project Languages - The project language refers to the default starting language assigned when a speech project is created. In Dialog Designer you can create and add project languages, which are primarily a convenient way to assign the ASR language, the TTS language, and the localization bundle language all at one time. Adding project languages also copies all existing prompts and phrases to a new language directory, so that you can translate them to another language.
Automated Speech Recognition (ASR) Languages - ASR languages are not installed as part of the Dialog Designer software. The ASR languages available to you depend on what languages are installed and available on your ASR server. When you add an ASR language to Dialog Designer, you must ensure that the language exists on the ASR server, or you might get unpredictable results with ASR requests.
Text-to-Speech (TTS) Languages - TTS languages are not installed as part of the Dialog Designer software. The TTS languages available to you depend on what languages are installed and available on your TTS server. When you add a TTS language to Dialog Designer, you must ensure that the language exists on the TTS server, or you might get unpredictable results with TTS requests.
Localization Bundle Languages - Language localization bundles are packaged with Dialog Designer, but not installed automatically during initial installation and configuration. If you find you need a localization bundle for your speech project, you can install it.
The current release of Dialog Designer includes the U.S. English language localization bundle.
Additional localization bundles can be obtained and installed as they become available. To receive updated information about the availability of localization bundles, contact your Avaya service representative or visit support.avaya.com.
