size Can be one of four possible settings: “none”, “small”, “medium”, or “large”.

Without attributes, a <break/> tag will insert a default-length brief break in the text.


<?xml version="1.0"?>
<vxml version="2.0">
        Let's have a moment of silence.
        <break time="5s"/>
        Okay. All done.
