Virtual Reality (VR): Speech Therapy

VRbal is a virtual reality (VR) speech therapy app that uses AI and machine learning (ML) to help stutter patients practice speech and overcome anxiety.

<My Role>

In a team of 5, my main role was the Instructional Designer and UX Designer. I also actively participated in the end-to-end product development cycle as a UX Researcher, which included conducting generative research, prototype design, and usability testing.

  • Adobe Design Achievement Awards, Semi-Finalist

  • Verizon Connected Futures III, Fellowship Award

<Project Background>

I worked with UX designers and engineers from NYU, SVA and Parsons in 2018 to design a VR experience that uses artificial intelligence to help stutter patients overcome social anxiety through exposure therapy techniques. We were awarded the Verizon Connected Futures III fellowship, selected as one of the twelve finalists of the US Microsoft Imagine Cup 2018, named as Semifinalist for Social Impact of the Adobe Design Achievement Awards in 2018, and received the Iron Award as part of the A’ Design and Award Competition in 2019.

My Design Process

*Below is a summary of the full product development cycle I project managed.

Step 1: Identify "The Problem & Target Audience"

VR Problem Background.001.jpeg

Stuttering is an incurable communication disorder, but symptoms can be alleviated through exposure therapy and pretend-play (Applied Behavior Analysis) with speech language pathologists. 


However, each therapy sessions are not easily accessible and affordable.

Step 2: Ideation


With the combination of VR, AI and speech therapy, stutter patients are put in a safe environment to rehearse speech therapy exercises and to practice job interviews in a 360 degree simulation scene.

Step 5: Prototype User Test

Developed prototypes were tested with members of the National Stuttering Association, Chapter in New York.


Step 6: Revise User Flow

The user flow was revised based on feedback received from the usability testing study.
