Dialogflow

Getting bored of having just a button-clicking chatbot and looking for something more intelligent? We have adopted Google's natural language processing engine, Dialogflow, to provide a higher level of experience to you.

Dialogflow incorporates Google's machine learning expertise and products and is built on Google infrastructure which can be optimized for the Google Assistant. It can process both voice and text-based conversation.

You need to first go to Dialogflow to create a project agent and then fill out the necessary information on our builder for setup: Client Email, Project ID, Private Key.

Usage

There are two things you need to manage to create a functioning Dialogflow chatbot:

• Perform training on Dialogflow console
• Set up responses to different intents on WOZTELL

For training on Dialogflow, you may refer to Dialogflow's documentation.

When you have completed setting up intents, you can select the created intents in Trigger and that node will be processed through Dialogflow. Click here for more details on how to set up a chatbot with NLP capability.
