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 daily practice habit that requires real effort over time.
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: Try the tools
Try DAF in your first session. Some people notice a change in their speech right away; effects vary, and they are not a cure. Altered auditory feedback can slow and smooth speech for some speakers while the tool is on.
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.
Keep showing up
Job interviews, phone calls, presentations. Feared-word practice. The point is a daily habit you can keep — not a Day-90 finish line.
Evidence-based techniques.
One session you will actually finish.
Daily dual-track session
You don't need a 90-day syllabus. You need a habit you will actually open.
Shape your speech, face a feared word, speak, then do one real-world thing. About 25 minutes — a 12-minute short day still counts.
Techniques SLPs actually use
Random breathing apps are not stuttering practice.
Easy onset, light contact, prolonged speech, pausing, cancellation, pull-out, preparatory set, and voluntary stuttering — with honest evidence tiers.
Speak, then transfer
Fluency in your room is not fluency in the world.
The speak step is a short AI conversation (phone, ordering, interview). Then one real-world mission from your actual feared situations.
Your feared words
Everyone has words they rearrange entire sentences to avoid.
Practice those words inside today's session until they lose their charge. The list follows you across devices.
Built for Consistent, Private Practice
No invented ratings or miracle claims—just an SLP-designed program you can use between real-world speaking moments.

This Isn't Positive Thinking.

fluency shaping effect sizes
Speech restructuring (gentle onset, light contact, prolonged speech) has among the strongest evidence for adults who stutter in systematic reviews.
70M
people worldwide stutter
You’re not broken. Stuttering is a neurological difference affecting about 1% of the population. Consistent practice can support change over time.
10 min
core daily practice
Short, repeatable sessions build the habit. Optional deeper practice when you have time — frequency matters more than marathon sessions.
“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 way to keep practicing between real-world speaking moments.
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.
