vhToolkitUnity is the Unity rendered version of the Virtual Human Toolkit. This project integrates several research systems together in order for the user to interact with a virtual human character through usage of text to speech and language understanding. Some of the systems that are integrated into his project are the Smartbody animation system, text to speech engines, and AcquireSpeech. Unity is a 3rd party proprietary rendering engine and is provided as binary-only with the Virtual Human Toolkit. You can download the free version of Unity here.
