Remarks

The prompts have their culture specified on the telephony session at the time when content is first added to the prompt. If the culture changes after some content is added, the prompt keeps the culture in effect before the content was added. If the prompt is cleared and new content is added, the culture is updated to the most recent culture.

When the TurnStarting event for the QuestionAnswerActivity occurs, the system determines the appropriate prompt to play. Because only the main prompt is required, it is possible that the appropriate prompt for a given situation might not be specified (that is, there might be nothing to play for the prompt). In these situations, the system relies on a fallback scheme, as summarized in the following table.

Note

If the fallback prompt is also unspecified, treat the fallback prompt as if it is the requested prompt and look for its fallback prompt.

Requested Prompt	Fallback Prompt
EscalatedSilencePrompt	SilencePrompt
SilencePrompt	HelpPrompt
HelpPrompt	MainPrompt
EscalatedNoRecognitionPrompt	NoRecognitionPrompt
NoRecognitionPrompt	HelpPrompt
RepeatPrompt	MainPrompt
