How it works

Something you live alongside, not a course you complete.

Calm Speech is a daily companion for people who stutter and stammer, with Aiden — a patient AI companion you can talk or type to — there throughout. Open it for two minutes or twenty. There’s no programme to finish and no week you’re behind on.

A calm first five minutes

No assessment and no test to pass. Just a few answers that shape the app around you.

1

One-tap sign-in

Sign in with Google. No passwords to make up or remember.

2

Six quick questions

Your goals, your first name, where you are in your journey, what feels hard, Aiden’s voice and a daily nudge time. Every answer shapes the app.

3

Choose Aiden’s voice

A range of natural voices, each with a sample to hear first, plus the speaking pace that suits you.

4

A first breath

The first thing the app asks is to rest, not perform: 90 seconds of breathing with the animated orb. Skip it if you like.

What’s inside

Five tabs — Today, Practice, Talk, Journal and Me — plus Prepare for upcoming moments. Features marked Premium are part of Premium; everything else is free.

01 · TODAY

An adaptive home, one thing at a time

Not a dashboard: one suggestion, one upcoming moment, one prompt.

  • A greeting from Aiden — a short personal line, written for that day.
  • Today’s small thing — one short exercise chosen from a rotation of 37, marked done in a tap.
  • Got something coming up? — the next call, interview or meeting shows here with its prep plan.
  • A daily prompt — a gentle question to write or speak about.
  • An effort streak — it counts the days you showed up, not how fluent you were.
  • Easier days — after a harder stretch, the home screen softens and upcoming events step back.

02 · PRACTICE

A steady habit, at your pace

Structured exercises, with new ones arriving without an app update.

  • Six techniques — Breathing, Easy Onset, Pacing, Prolonged Speech, Reading and Voluntary Stuttering — six sessions each, laid out as a ladder. Nothing is locked.
  • A weekly theme — a focus for the week that ties the day’s practice together.
  • Guided sessions — a timer, rounds, clear instructions and the breathing orb while you read or speak aloud.
  • Feedback after each sessionPremium — Aiden’s note, what stood out as neutral counts (blocks, repetitions, prolongations, interjections), your speaking rate, and one tip to try next.
  • Scores are opt-in — a fluency score appears only if you switch it on in Settings.

03 · TALK

Four ways to use your voice

With Aiden, the app’s AI companion — out loud when you want to, typed when you don’t.

  • Chat with AidenPremium — a live voice conversation: he listens as you talk and starts replying aloud within moments. Switch to typing any time in the same thread — typing is always free.
  • Rehearse a real momentPremium — 38 situations across everyday life, work, social, service, health and education. Aiden plays the other person: patient by default, tougher only if you ask — and if you seem upset, he steps out of role to check in.
  • Live DAFPremium — delayed auditory feedback plays your voice back through headphones after a short delay you set (50–300 ms). A long-established technique that helps many people slow down.
  • Guided warm-ups — 31 short breathing and pacing flows for before a moment, paced by the breathing orb.

04 · PREPARE

Ready for the real thing

For a specific moment that’s coming up.

  • Add an upcoming event — a date, a time and the kind of situation: a call, an interview, a date or a presentation.
  • Start with breath — a three-step warm-up matched to the situation: paced breathing with the orb, slow reading, then easy-onset sounds.
  • An AI prep planPremium — a small plan of breath, warm-up and optional role-play, made for that moment. Swap any step for an alternative.

05 · JOURNAL

Write it or say it

Voice and writing are equal here.

  • Written entries and voice notes — whichever feels easier that day. Voice notes are transcribed.
  • A daily prompt — a question to start from on days when a blank page is too much.
  • Aiden’s reflectionPremium — a short, warm reflection on any entry, with a follow-up question to Aiden right from it.
  • A weekly reviewPremium — a short letter from Aiden on your week: one pattern he noticed and three quiet numbers. Never a scoreboard.

MEET AIDEN

A companion, not a feature

Aiden is Calm Speech’s AI companion, available by voice or text across the app — and about anything, not only speech.

Answers properly — at whatever length a question deserves, and looks things up when the answer depends on today.

Remembers what matters — a few short facts — “is a teacher”, “dreads phone calls”, “prefers short answers” — so you don’t repeat yourself. It never keeps what you said, and every fact can be deleted.

A tone you choose — Warm (gentle and encouraging), Direct (brief, no cushioning) or Light (relaxed, humour welcome). Respect and patience hold in every tone.

Knows you, quietly — your onboarding answers tailor his help. A question about a phone call gets advice about the call — never an unprompted comment about your stutter.

Safe in hard moments — if someone is in danger or talks about self-harm, Aiden sets everything aside, responds with care, and points to real help where they live.

What Calm Speech is not

Worth being blunt about, so nobody arrives expecting the wrong thing.

Not a cure

No app can cure stuttering, and we don’t use the word. Fluency isn’t the target.

Not a replacement for an SLP

If you work with a speech-language pathologist, keep working with them. This sits alongside.

Not a fluency test

Nothing grades you. Practice feedback is neutral counts and one tip, and a fluency score exists only if you switch it on.

Works alongside therapy

Calm Speech is not competing with your speech-language pathologist. It fills the gap between appointments, where most of the actual living happens, and it won’t contradict stutter-affirming practice.

Nothing is gated behind a clinician, and nothing in the app tells you a technique is mandatory.

For speech-language pathologists

What you share stays yours

Journal entries are never scored or sold. Aiden keeps only a few short facts you can delete — never what you said — and there’s no ad-tech profiling anywhere in the product.
