Vocal Willow-Software

Vocal Willow is a multi-sport, audio-first training ecosystem designed to give blind and visually impaired athletes complete independence in their practice, while also serving as an elite, screen-free swing analysis tool for sighted players. By mounting a low-cost, IMU-based sensor to the handle of a bat or paddle, the system analyzes raw physics to detect swings and ball impacts in real-time. It then delivers instant spoken feedback—such as hit quality, g-force intensity, or rally counts—directly to a companion mobile app in five Indian languages. Currently supporting Cricket, Paddleball, and Pickleball, Vocal Willow allows athletes to keep their focus entirely on the game, relying on precise audio and haptic feedback to refine their mechanics without needing a coach in the loop or a screen to look at.
