The <break> tag instructs the TTS engine to insert a pause in the synthesized text.
Can be one of four possible settings: “none”, “small”, “medium”, or “large”.
A duration of time specified with the appropriate measurement (e.g., 300ms for three hundred milliseconds).
Without attributes, a <break/> tag will insert a default-length brief break in the text.
<?xml version="1.0"?><vxml version="2.0"><form><block><prompt>Let's have a moment of silence.<break time="5s"/>Okay. All done.</prompt></block></form></vxml>
The output of the above script would be:
Computer: Let's have a moment of silence. Computer: (5 seconds of silence) Computer: Okay. All done.
