Practice public speaking in the virtual space.

An AI-Powered Virtual Reality Application


1% of the total population who suffer from a neurological disorder called stuttering often find social scenarios stressful. VRbal was created with a mission to make practicing for these scenarios easier with artificial intelligence in virtual reality.


Artificial Intelligence



The AI agent enables a virtual environment that adapts to the user’s needs as training progresses. It collects users' feedback and to customize the training for them, allowing a socially safe and optimized learning experience that can build communication skills.

On a scale of 1 to 10, how are you feeling today?



Multiple Difficulty Levels

There are several built-in difficulty levels within VRbal, allowing users to practice with different types of environment, noise levels and numbers of audience based on their levels of comfort.




Relaxation Scenes

Before each level, users can pick a relaxation scene to practice challenging words or vowels or just relax. These scenes are customized based on their preferences and comfort levels.

Do you want to practice deep breathing or vowels pronunciation?
