PAD Fluency Profile — FluentPlay

FluentPlay

Six-axis PAD fluency profile, across four treatment stages.

3D visualization · illustrative data

PAD · 64/016,001

Isolate stage

Shape · full trajectory

Six axes, four stages, one shape over time.

Each polygon is a complete PAD profile — six axes radiate from a central spine, with vertex distance equal to score × r_max. Stacked across four stages, the shape grows outward as pre-articulatory timing becomes more stable.

01 · Axes

Six axes, each surfacing a different dimension of pre-articulatory stability.

PAD v1 · Six-dimensional

01 / 06

Pressure Reduction

How much subjective strain the speaker carries across a session. Lower pressure correlates with more stable motor timing on the pre-articulatory window.

02 / 06

Anxiety Reduction

Anticipatory anxiety surrounding feared sounds or phrases. Acoustic and prosodic correlates surface in the signal before articulation onset.

03 / 06

Ground Strength

Breath support and phonation onset quality. Without ground, every other axis compresses — the profile sinks toward center.

04 / 06

Fluency Rate

Syllables per minute at stable PAD score. Not raw speed — stability-adjusted speed. Fast and unstable rates score lower than slow and stable.

05 / 06

Session Consistency

Variance across sessions — are profiles returning similar shapes over time? High variance scores low; locked-in practice scores high.

06 / 06

Phoneme Range

Coverage across the phoneme inventory. A speaker can be fluent on /m/ and collapse on /p/ — this axis makes that pattern visible.

02 · What PAD measures

Timing instability before the block, not after.

Most speech-fluency tools measure what happens at and after the moment of disfluency — the block, the repetition, the prolongation. PAD measures the pre-articulatory window — the motor timing instability in the milliseconds before speech onset. That earlier signal is what makes the six-axis profile possible.

The framework is not a single score. It is a multi-dimensional surface: six axes derived from acoustic, prosodic, and timing features, scored per session, stacked across the arc of treatment. A profile is a shape. A treatment arc is a shape changing over time.

Clinicians, researchers, and digital therapeutic partners can use the PAD framework as an independent instrument — for outcome measurement, for validation of other tools, or as the scoring layer inside their own platform.

PAD score definition

D = P × A × (1 − G · λ)

Disfluency index = Prediction × Acoustic × (1 − Gate · λ). Full scoring framework detailed in the provisional filing.

The full picture

The first platform to measure what happens before the block.

The audio pipeline captures pre-articulatory timing instability in real time. PAD scores it per syllable. Every game in the FluentPlay library ships with both layers hardwired in. The pipeline and the scoring framework are architecturally independent — licensable separately or as an integrated stack. Patent pending under U.S. Provisional 64/016,001.
