BargeIn Property

Gets or sets whether playback of the DialogPrompt control can be interrupted by user speech or telephone keypad input. Read/write.

Usage

Remarks

A BargeIn value of True enables the DialogPrompt to be interrupted; a value of False prevents it from being interrupted.

Specify the BargeInType with a Param control contained in a Params collection.
