Voice Scripting uses Unity’s Visual Scripting
What is Visual Scripting? — it’s one of the trendy new ways to learn how to code. Children are doing it.
Aspiring developers are using it. Artists, animators, and game designers are picking it up very quickly.
Visual Scripting is a tool that uses a graphical interface to help the developer create programs based on visual representations of logic rather than writing it out in the required language syntax like in a programming language like C#.
Voice Scripting extends Visual Scripting to Dialogflow. The primary interface is Dialogflow Intents Responses. So you might interface with Dialogflow with your voice and when Dialogflow has finished it will send an Intent Response that will instruct how to handle the response in a Unity world.
