Dialog Designer Elements are designed to be vendor-neutral as it pertains to speech recognition, and have been tested using both Nuance and IBM speech recognition engines.

All prompting and caller input is designed around a directed dialog (DD) paradigm in which the caller is directed to speak one datum per prompt.

The initial set of Dialog Designer Elements as released have been localized to support English-speaking callers via pre-recorded professional voice quality prompts and U.S. English speech recognition grammars and Text-to-Speech (TTS) capabilities. Developers can easily modify the Dialog Design Elements and replace the pre-recorded prompts in order to support additional languages for both speech recognition and TTS.
