StutterLab Is Not For Everyone
We'd rather be honest upfront than waste your time.
Children
StutterLab is designed for adults. Pediatric stuttering requires direct SLP supervision.
People looking for a quick fix
There is no magic cure for stuttering. This is a 90-day training program that requires real effort.
People who can’t commit to 10 minutes a day
Consistency is everything. If you can’t practice daily, this won’t work.
A Real Training Program.
Not Another Meditation App.
Day 1: Feel the Difference
Try DAF in your first session. Most people feel an immediate change in their speech. It’s not magic — it’s neuroscience. Your brain responds to altered auditory feedback by slowing and smoothing your speech patterns.
Days 2–14: Build Your Toolkit
Learn gentle onset, pausing, light contact. Practice conversations with AI. Complete your first real-world challenge. By Day 14, you’ll have 5 techniques you can use anywhere — not just in the app.
Days 15–90: Transform
Advanced AI scenarios: job interviews, phone calls, presentations. Feared Words mastery. CBT for speech anxiety. By Day 90, you won’t need us anymore. That’s the point.
Everything Your SLP Uses.
Available 24/7 in Your Browser.
Audio Lab
You've been told to "just slow down." That's not how it works.
DAF, FAF, Choral Speaking & Metronome — the same clinical tools SLPs use, in your browser. Delayed Auditory Feedback alone reduces stuttering by up to 80% in clinical studies.
Phone Call Simulator
Phone calls are the #1 feared situation for people who stutter.
Practice calling the doctor, ordering takeout, handling customer service — with an AI that responds naturally. Fail safely. Build real confidence.
AI Conversation Practice
You can't practice a job interview with a YouTube video.
Adaptive AI conversations for interviews, dates, meetings, presentations. It listens to you speak, detects your patterns, and adjusts difficulty in real time.
Feared Words Trainer
Everyone has "those words." The ones you rearrange entire sentences to avoid.
Add your personal trigger words. Practice them with gentle onset, cancellation, and pull-out techniques until they lose their power over you.
90-Day Curriculum
Random exercises don't work. You need a structured program.
10 minutes a day. Each session builds on the last — from breathing basics to real-world phone calls. Designed by an SLP, not a product manager.
CBT & Mindfulness
Stuttering is 50% motor, 50% anxiety. Most apps ignore the anxiety.
Thought records to reframe catastrophic thinking. Guided breathing for pre-call anxiety. Prediction testing to prove your fears wrong.
Real-World Challenges
Practicing alone is safe. But fluency lives in the real world.
Daily micro-missions: order at a counter, greet a stranger, make a phone call. Earn XP, build streaks, and prove to yourself it gets easier.
Voice Journal & Analytics
"Am I actually getting better, or does it just feel that way?"
Record yourself daily. AI tracks your fluency rate, speech patterns, and anxiety trends over time. See the proof in your own data.

From the Stuttering Community
Real stories from people who stutter — proving that your voice is not your limitation.
From Stutter to Commercial Pilot
Real Story“I just passed my Commercial Pilot certification, and honestly, it still feels surreal. I’ve been a lifelong stutterer, and it’s something I’ve battled for as long as I can remember. There were moments growing up when I questioned whether aviation was even realistic for me, especially in a field where communication is everything. Over time, though, I learned something important — the fear of stuttering is a mile wide and an inch deep. The anticipation is always worse than the moment itself. Aviation has always been my passion, and I decided I wasn’t going to let fear dictate my future. I worked through the uncomfortable radio calls, pushed through the blocks, and kept showing up. Little by little, confidence replaced fear. If you’re hesitating to chase your passion because of a stutter, don’t. Your voice is not your limitation. The fear feels big, but it shrinks every time you lean into it.”

This Isn't Positive Thinking.
It's Neuroscience.
80%
fluency improvement with DAF
Delayed Auditory Feedback is one of the most-studied interventions in stuttering research. It changes how your brain processes speech in real time.
70M
people worldwide stutter
You’re not broken. Stuttering is a neurological difference affecting 1% of the population. Consistent practice works because of neuroplasticity.
10 min
daily practice changes brain structure
fMRI studies show that consistent speech practice literally rewires the neural pathways responsible for fluency. Frequency matters more than duration.
“My Patients Needed a Way to Practice Between Sessions”
I built StutterLab because I watched my clients make incredible progress in our sessions — then come back a week later having lost momentum. They didn't need more willpower. They needed a tool that put clinical-grade practice in their pocket.
Every exercise, every AI conversation prompt, every progression in this curriculum is built on peer-reviewed fluency shaping and stuttering modification research. This isn't a wellness app with a speech theme. It's a training program.
