SpVoice Skip method (SAPI 5.3)

  • Article

Microsoft Speech API 5.3

Object: SpVoice

Skip Method

The Skip method skips the voice forward or backward by the specified number of items within the current input text stream.

  
    SpVoice.Skip(
     Type As String,
     NumItems As Long
) As Long

Parameters

  • Type
    The type of items to be skipped. Currently, Sentence is the only type supported.
  • NumItems
    The number of items to be skipped forward in the voice input stream. A negative value specifies skipping backward.

Return Value

A Long variable containing the number of items skipped.

Example

The following Visual Basic form code demonstrates the use of the Skip method. To run this code, create a form with the following controls:

  • A text box called Text1
  • Two command buttons called Command1 and Command2
  • An HScrollbar control called HScroll1

Paste this code into the Declarations section of the form.

The Form_Load procedure creates a voice, sets up the HScrollbar with a value of -2 in a range from -5 to 5, and puts a string of numbers in the textbox. Because the numbers are followed by periods and separated by spaces, SAPI considers each number to be a sentence. The scrollbar specifies the number of sentences that the voice object will skip.

Click Command1 to start the voice speaking the sentences in the textbox. Click Command2 to skip the voice forward or backward, depending on the value of the scrollbar control. Click the left side or the right side of the scrollbar to increase or decrease the number of sentences to be skipped by the Command2 button.
