How to configure SSML in Dialogue Studio

Speech Synthesis Markup Language (SSML) is an XML-based markup language for speech synthesis applications.

Based on you speech engine a different format needs to be used:

We are going to start with a “Incoming conversation” node. This node only listens to audio/video and is connected to our server using SignalR.


  1. Drag and drop Incoming Call Node

  2. Open Node

    1. Select / Configure server

    2. Filter on Audio/Video

Next creating the SSML text we want to use. This can be done by using a function node.


  1. Drag and drop Function Node

  2. Open Node

    1. Enter text you want to play.

      Example Microsoft Text to Speech:

      /*jshint multistr: true */

      msg.text =' <speak version="1.0" xmlns="http://www.w3.org/2001/10/synthesis" xml:lang="en-EN">\

      Here are <say-as interpret-as="characters">SSML</say-as> samples.\

      I can pause <break time="1s"/>. \

      I can speak in cardinals. Your number is \

      <say-as interpret-as="cardinal"> \

      10 \

      </say-as>. \

      Or I can speak in ordinals. You are \

      <say-as interpret-as="ordinal">\


      </say-as> in line.\

      Or I can even speak in digits. The digits for ten are\

      <say-as interpret-as="characters">\



      I can also substitute phrases, like the \

      <sub alias="World Wide Web Consortium"> \



      Finally, I can speak a paragraph with two sentences.\


      <s>This is sentence one.</s>\

      <s>This is sentence two.</s>\


      Today is <say-as type="date:mdy"> 11/20/2019 </say-as> \

      I <emphasis level="strong">really</emphasis>\

      Like pepperoni on my pizza.\

      <audio src="http://localhost/applause8.mp3"> \

      applause <!--when file is not loaded--> \



      return msg;

  3. Connect end of Incoming Call node with Function Node

Next we are adding an “Say”, to play the SSML text.


  1. Drag and drop Say Node

  2. Open Node

    1. Set message to: msg.text

  3. Connect end of Function Node with begin of Say node
