voicexml.nomatchHandlerPrompt
Prompt played if a nomatch event is thrown and not handled by the application.
The nomatch event is thrown if the caller’s utterance cannot be recognized by the current active grammars. The default is nomatch.wav located in %NSSSVRSDK%\master\vbs_basepath\lang\en-US\prompts. %NSSSVRSDK% is the location of the Nuance Speech Server.
If the prompt fails to load, the TTS version is played instead.
This service property takes only the filename of the prompt to play as its value, not its location.
See Step 5: Localize the default system prompts for information on localizing this prompt.
