Interface: ISpeechRecoContext
RequestedUIType Property
The RequestedUIType property specifies the UIType of the last UI requested from the engine.
After a speech recognition (SR) engine sends a RequestUI event, the UIType persists until the next RequestUI event. This way the application can check for the last requested UI type. If no UI has been requested, the UIType string will be Empty.
Syntax
Set: | (This property is read-only) |
Get: | String = SpeechRecoContext.RequestedUIType |
Parts
- SpeechRecoContext
- The owning object.
- String

Set: (This property is read-only)
Get: A String variable specifying the UIType. The UIType is a String corresponding to the UI requested.
Remarks
See RequestUI event and ISpeechRecognizer.DisplayUI for more information.Example
The following Visual Basic form code demonstrates retrieving the UI last requested from the engine. Due to the complexity of replicating a RequestUI, the UI this code retrieves is a zero-length string. To run this code, paste it into the Declarations section of a form that contains no controls.
Option Explicit
Private Sub Form_Load()
Dim RecoContext As SpInProcRecoContext
Dim T As String
Dim UI As String
On Error GoTo EH
Set RecoContext = New SpSharedRecoContext
UI = RecoContext.RequestedUIType
If Len(UI) = 0 Then
T = "No user interface type has been requested by the engine."
MsgBox T, vbInformation
End If
End
EH:
If Err.Number Then ShowErrMsg
End Sub
Private Sub ShowErrMsg()
' Declare identifiers:
Dim T As String
T = "Desc: " & Err.Description & vbNewLine
T = T & "Err #: " & Err.Number
MsgBox T, vbExclamation, "Run-Time Error"
End
