Supporting clinicians, empowering speakers

Speak with
confidence.

Evidence-based software for speech therapy: a review workbench that gives SLPs objective measures of every session, and guided practice that keeps speakers progressing between sessions.

About StutterStep

Step into confidence.

Speaking with confidence isn't a given for everyone. Whether you stutter, are working through another speech difference, or simply want to be heard more clearly, we build tools that turn daily practice into measurable progress, for speakers, the clinicians who support them, and the developers building what's next.

Make evidence-based speech support available to everyone, every day, not just one hour a week. Practice that meets your voice where it is, and grows with you.

Your voice stays yours. On-device processing where possible, encrypted everywhere else. Your recordings are never sold and never used without your consent.

Individual from $12/mo. SLP practices from $49/mo. API metered, with a free tier to get building.

What's inside

Built for daily voices and busy clinics

Three specialist models

Fluency, pacing, and clarity models score every session against your own baseline.

Practice that fits your day

Short guided sessions with real-time feedback, built around techniques clinicians already use.

The SLP Workbench

The model flags disfluencies on real audio; clinicians confirm the calls and keep the record.

Direct Zoom integration

Telehealth sessions stream straight into the Workbench, with live pacing cues during the call.

One-click reports

School, IEP, and progress summaries assembled from confirmed labels, ready to send.

Private by design

On-device processing where possible, encrypted everywhere, and clinic data never trains models.

Where your voice goes

Three products. Three separate paths.

SLP

HIPAA

A separate, HIPAA-protected platform. Client data stays with the clinic, never used for model training.

Individual

Trains models

Anonymized practice audio helps our models get better for everyone. We start with how you speak, not what you say.

API

HIPAA

Separate, HIPAA-protected infrastructure. Audio in, metrics out, never used for training by default.

Model training

fluency · pacing · clarity

Disfluency detection

Flags blocks, prolongations, and repetitions the moment they happen.

Pacing & rhythm

Tracks syllable rate, pauses, and easy onsets across a whole session.

Clarity & intelligibility

Measures how clearly each word lands, then trends it week over week.

Personal baselines

Learns your starting point and scores progress against you, not others.

Individual audio is anonymized before training, and you can opt out anytime. API keys choose per-key whether to share training data in exchange for lower rates; healthcare workloads typically keep it sealed.

Grounded in evidence

Built on peer-reviewed speech science

How we approach speaking

Speaking well isn't about sounding like everyone else, it's about being heard. We build speaking confidence the way you'd build any skill: short, structured practice, every day, with feedback you can trust.

Whether you stutter, are working through a motor-speech condition, or simply want steadier delivery, each session applies techniques clinicians already use, easy onsets, pacing, and breath support, to real speech, not drills in isolation.

Our models listen for the moments that matter: where speech flows, where it catches, and how pace and clarity shift week over week. Rather than scoring you against other people, the model learns your baseline and measures progress against it.

That picture of progress is shared with you (and, if you choose, your SLP) so practice and therapy finally point in the same direction.
