StutterGuide

Swift Student Challenge 2026 Winner 🏆

An iOS app that helps children who stutter build awareness of word repetitions through real-time speech recognition.

About

StutterGuide provides a safe, judgment-free space for practicing reading aloud. The app listens as you read sentences and gently identifies when you repeat words (like "the the dog"), helping build awareness of speech patterns.

Built from personal experience: at age 3, I couldn't speak like other kids and spent years in remedial speech classes. This is the patient companion I needed back then.
