About SwiftSpeech A free, on-device speech-practice app that helps children who stutter or are working on fluency build confidence through short, illustrated daily quests. Every week brings a new original story, a few minutes of guided practice, and a quiet moment to reflect on how it felt. Where It Came From SwiftSpeech was built by Samarth Gaggar, who lived with a stutter through childhood. When his younger brother started down the same road, Samarth wanted to give him the kind of patient, structured, kid-first practice that did not exist when he was small. Every screen, every line of code, and every illustration is shaped by that lived experience and a simple belief: confident speech is something every child can grow into. What's Inside A 52-Week Journey of Original Stories Fifty-two illustrated read-aloud stories with short daily exercises, moving from breathing basics to confident storytelling. The On-Device AI Practice Lab Four listening exercises, Echo Mirror, Pace Coach, Tongue Twister Lab, and Conversation Quest, with live feedback and audio that never leaves the phone. Practice Journal A private, on-device space to log mood, feelings, and notes after practice so kids and parents can talk about how it felt, not just how long they practiced. Stars, Stamps, and a Sticker Album Gentle milestones and visual Foundations -> Flow -> Confidence map, no leagues, no pressure, no hearts to lose. Parent View Calm progress snapshots linked by Student ID, plus recent journal reflections to spark easy conversations at home. Schools and Clinics Organization Codes for teachers and SLPs to manage classes, customize plans, and export PDF discharge reports. Designed for Young Users No ads, no in-app purchases, spoken instructions for early readers, and microphone audio processed entirely on-device. No ads. No in-app purchases. Secure sign-in. Spoken instructions for kids who don't read yet. Microphone audio stays on the device. Who It Helps Children who stutter or are working on pronunciation, families practicing between therapy visits, and SLPs, schools, and early-intervention teams looking for a structured at-home tool.
