Step 3 Insert Text to Speech Service

Insert text to speech node from IBM Watson palette and connect to output of delay node

Get Access to Text To Speech

• Log into IBM Cloud and Go to IBM Cloud Catalog

• Search for Text to Speech Service within Catalog

• Create Lite Service

• Go to created Service and get service credentials for Text to Speech node

• Set up node properties with username , password and API key from service credentials

Step 4 : Insert play audio node

Insert play audio node . Node might need to be installed within the Manage palette in hamburger menu
