For you · Speech-language pathologists
A between-sessions companion you can trust.
Calm Speech is a non-clinical daily companion for adults and older teens who stutter. It tracks effort rather than fluency, so it supports the work you do in session instead of quietly pulling against it.
Free for clients to start, on iOS and Android.
The gap between appointments
Your clients see you for an hour. They live the other hundred and sixty-seven, and that is where avoidance, anticipation and self-talk do most of their work.
Most apps that fill that gap are built on fluency-scoring. A client who has spent a session doing careful desensitisation work then opens an app that grades their speech and reintroduces the idea that fluency is the measure of a good day. In Calm Speech, a fluency score stays off unless your client chooses to turn it on.
How it fits clinical practice
Effort first, scores off
The app counts participation: small things done, sessions chosen, entries written. Practice feedback reports blocks, repetitions, prolongations and interjections as neutral counts with speaking rate — observations, not grades. A fluency score appears only if the user switches it on.
Client autonomy by design
Six techniques — Breathing, Easy Onset, Pacing, Prolonged Speech, Reading and Voluntary Stuttering — each a six-session ladder with nothing locked. The client chooses what to open, which supports the self-management goals you set.
Rehearsal between sessions
Clients can rehearse 38 real situations with Aiden, the app’s AI companion — calls, interviews, ordering, appointments. Patient by default, harder only on request, and he steps out of role to check in if the client seems upset.
Tools you’ll recognise
Live DAF with an adjustable 50–300 ms delay, 31 guided breathing and pacing warm-ups, and a three-step warm-up before an upcoming moment: paced breathing, slow reading, easy-onset sounds.
Affirming language throughout
No cure framing, no “correction”, and no correcting stammer to stutter. Techniques are offered as options, never as prescriptions, and Aiden never makes unprompted comments about a client’s stutter.
Safe in hard moments
If a client is in danger or talks about self-harm, Aiden sets everything aside, responds with care, and points to real help where they live.
