  3. Locate the TTSVOICE action and place a SNIPPET action and a PLAY action after it. Connect them. If the script already has a SNIPPET action in this location, you can use the existing instance.

  4. In the SNIPPET action, add a line for a variable assignment. Set the variable value to be the SSML markup you wrote. For example:

    ASSIGN playSSML = "[SSML markup]"

  5. Configure the Play action's Sequence property with the name of the variable you added to the SNIPPET action. Include a percent sign ( % ) as a string reference character before the variable name to identify the value of the variable as text. Enclose the string reference character and variable name in double quotes. Enclose the variable name in curly brackets. For example: "%{playSSML}".
