Vrbal is a smart VR experience that uses machine learning to help the user prepare for a specific anxiety-inducing event of their choice. The AI agent enables a virtual environment that adapts to the user’s needs as training progresses. There are several built-in difficulty levels within Vrbal, thus allowing users to practice with different types of environments, noise levels, and audience sizes based on individual comfort levels. Before each level, users can pick a relaxation scene to practice challenging words, vowels or to simply relax.
