# How Speech Clarity Is Measured and Progress-Tracked

Speech clarity (ICF b320) is measured through intelligibility sampling, phonetic/phonological inventory, connected-speech analysis and generalisation probes. Progress is tracked by re-measuring these parameters against the child's own baseline at fixed intervals, with defined criteria driving advancement through the target hierarchy. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional.

*Speech clarity isn't a single number — it's a pattern of intelligibility we map, baseline against the child's own profile, and re-measure session by session.*

## In short
Within a therapy plan, speech clarity (ICF **b320**, articulation functions) is measured through structured intelligibility sampling, single-word and connected-speech analysis, and standardised criterion-referenced probes. Progress is tracked by re-measuring the same parameters at fixed intervals against the child's own baseline — not against a generic norm — so the therapist can see whether targeted sounds and overall intelligibility are gaining real-world stability.

## The science of measurement
Clinicians triangulate several data layers rather than relying on one score:

- **Percentage intelligibility** — proportion of utterances understood by a familiar versus unfamiliar listener, sampled in structured and spontaneous contexts.
- **Phonetic & phonological inventory** — which target phonemes are stimulable, emerging, mastered, or in error, plus active phonological processes.
- **Connected-speech analysis** — clarity under load (running speech), where coarticulation and rate effects surface.
- **Generalisation probes** — whether a target sound holds across word positions, untrained words, and untrained settings (home, classroom).
- **Functional carryover** — caregiver- and teacher-reported intelligibility in daily communication.

Each target carries a defined criterion (e.g. accuracy across a set of probe items over consecutive sessions before advancing the hierarchy). Plotting these data points across the therapy block shows trajectory, plateau, or the need to re-cue the target.

## Tracking within the plan
Baseline probes anchor the plan; session-level data and periodic re-sampling chart movement. When generalisation stalls, the therapist adjusts cueing level, complexity, or dosage — the measure drives the method.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — our AbilityScore® is a clinician-administered structured assessment, never an online figure. Drawing on 2.5 billion+ data points and 25 million+ therapy sessions, our therapists convert these intelligibility measures into a working plan.
