Public Property ConfirmationThreshold As Single

[GlobalizedCategoryAttribute("SpeechCategory")] 
[DefaultValueAttribute(1)] 
[GlobalizedDescriptionAttribute("DialogActivityCommon_ConfirmationThreshold")] 
public float ConfirmationThreshold { get; set; }

Property Value

A Single whose value ranges from 0.0 to 1.0. The default value is 1.0, which means that confirmation always occurs.

Example

The following example creates a MenuActivity instance and sets a number of properties on the instance. In the highlighted line of code, ConfirmationThreshold is set to 0.8, which causes any response whose confidence level is 0.8 or less to be passed to the confirmation stage.

this.chooseSize = new Microsoft.SpeechServer.Dialog.MenuActivity();
this.chooseSize.CanBargeIn = true;
this.chooseSize.ConfirmationThreshold = 0.8F;
this.chooseSize.DataField = "";
this.chooseSize.DataMember = "";
this.chooseSize.DataSource = null;
this.chooseSize.CompleteTimeout = System.TimeSpan.Parse("00:00:01.5000000");
this.chooseSize.InitialSilenceTimeout = System.TimeSpan.Parse("00:00:01.5000000");
this.chooseSize.Name = "chooseSize";
this.chooseSize.SynonymsField = "";
this.chooseSize.UseDefaultGrammars = true;
this.chooseSize.ConfirmationTurnStarting += new System.EventHandler<Microsoft.SpeechServer.Dialog.TurnStartingEventArgs>(this.chooseSize_ConfirmationTurnStarting);
this.chooseSize.TurnStarting += new System.EventHandler<Microsoft.SpeechServer.Dialog.TurnStartingEventArgs>(this.chooseSize_TurnStarting);
this.Activities.Add(this.chooseSize);
