Examples

When the Tellme VoiceXML interpreter executes the following VoiceXML document it converts the string "Hello World!" to speech, plays that string to the user, and then transitions to the main Tellme service menu.

<?xml version="1.0"?>
<vxml version="2.1"
 xmlns="http://www.w3.org/2001/vxml">
<form>
   <block>
      Hello World!
      <exit />
   </block>  
</form> 
</vxml>
