Pause Method

  • Artikel
  Microsoft Speech Technologies Homepage

Pauses playback of the current subqueue without flushing the audio or otherwise affecting the subqueue.

PromptQueue.Pause()

Remarks

The Pause method has no effect if playback is already paused or stopped. Note that the Pause method is a synchronous method that returns 0 if the subqueue is successfully paused, or -1 if it is not. While playback is paused, subsequent calls to the Start method of either the prompt element or the PromptQueue element have the expected result of delimiting subqueues. Playback remains paused, however, until the Resume method is called.

Example

The following code demonstrates the use of the Pause method.
