PhonemeId Property

The PhonemeId property retrieves the ID of the current phoneme being spoken by the voice.


Set: (This property is read-only)
Get: Integer = ISpeechVoiceStatus.PhonemeId


The owning object.
Set: (This property is read-only)
Get: An Integer variable returning the Phoneme ID.


The following Visual Basic form code demonstrates the use of the PhonemeId property of an ISpeechVoiceStatus object. To run this code, create a form with the following controls:

  • A command button called Command1
  • Two text boxes called Text1 and Text2

Paste this code into the Declarations section of the form.

The Form_Load procedure creates a voice object and places a sentence in the text box. The Command1_Click procedure speaks the contents of the text box asynchronously, and loops until the voice has finished speaking. Inside the loop, the code checks PhonemeId property periodically and displays it in Text2.

Option Explicit

Private V As SpeechLib.SpVoice

Private Sub Command1_Click()
    Dim ii As Integer

    On Error GoTo EH

    Text2.Text = ""
    V.Speak Text1.Text, SVSFlagsAsync

        For ii = 0 To 20000
        Next ii
        Text2.Text = Text2.Text & V.Status.PhonemeId & " "

    Loop While V.Status.RunningState = SRSEIsSpeaking

    If Err.Number Then ShowErrMsg
End Sub

Private Sub Form_Load()
    On Error GoTo EH

    Set V = New SpVoice
    Text1.Text = "way, we, why, woe, woo."
    Text2.Text = ""

    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"
