SpVoice Pause method (SAPI 5.3)
Microsoft Speech API 5.3
The Pause method pauses the voice at the nearest alert boundary and closes the output device, allowing it to be used by other voices.
The following Visual Basic form code demonstrates the use of the Pause and Resume methods. To run this code, create a form with the following control:
- A command button called Command1
Paste this code into the Declarations section of the form.
The Form_Load procedure creates a voice object. The first call of the Command1_Click procedure causes the voice to begin speaking a text stream. Subsequent Command1 clicks alternately pause and resume the voice. When the voice has finished speaking the stream, the EndStream event procedure causes the voice to speak it again.
The voice's AlertBoundary setting of SVEPhoneme means that the Pause method can interrupt the voice within word boundaries. The text stream spoken contains a number of long words in order to show this interruption of words more clearly.
