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:

• Microsoft Text to Speech: https://learn.microsoft.com/en-us/previous-versions/office/developer/speech-technologies/hh378377(v=office.14)

• Microsoft Cognitive Services: https://learn.microsoft.com/en-us/azure/ai-services/speech-service/speech-synthesis-markup?tabs=csharp

• Google Cloud Text to Speech: https://developers.google.com/assistant/actions/reference/ssml#markupSSML

Configure

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.

Steps:

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.

Steps:

1. Drag and drop Function Node

2. Open Node

   1. Enter text you want to play.

      Example Microsoft Text to Speech:

      Copy

      Function

      msg.text = '<p>\
      <s 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"> 10 </say-as> in line.\
      Or I can even speak in digits.\
      The digits for ten are <say-as interpret-as="characters"> 10 </say-as>.\
      I can also substitute phrases, like the <sub alias="World Wide Web Consortium"> W3C </sub>.\
      Finally, I can speak a paragraph with in multiple languages.\
      </s>\
      </p>\
      <p>\
      <s xml:lang="en-EN">I can speak english</s>\
      <s xml:lang="nl-NL">Ik kan nederlands spreken.</s>\
      <s xml:lang="de-DE">Ich kann Deutsch sprechen</s>\
      </p>\
      <p>\
      Today is <say-as type="date:mdy"> 11/20/2019 </say-as> \
      I <emphasis level="strong">really</emphasis> like pepperoni on my pizza.\
      </p>'
      return msg;

3. Connect end of Incoming Call node with Function Node

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

Steps:

1. Drag and drop Say Node

2. Open Node

   1. Set message to: msg.text

   2. Set method to: SSML

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