BargeIn Property

  • Article
  Microsoft Speech Technologies Homepage

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

Usage

ASP.NET markup: <speech:Prompt BargeIn="..." />
Get value: Boolean = DialogPrompt.BargeIn;
Set value: DialogPrompt.BargeIn = Boolean;
Data type: System.Boolean
Required: No; Default: True

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.

Example

In the following example, the DialogPrompt contained in the first QA control can be interrupted by successful recognition of a city name. The DialogPrompt contained in the second QA control cannot be interrupted.

<form id="Form1" method="post" runat="server">
  ...
  <speech:semanticmap id="TheSemanticMap" runat="server">
