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.","answer_md":"*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.*\n\n## In short\nWithin 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.\n\n## The science of measurement\nClinicians triangulate several data layers rather than relying on one score:\n\n- **Percentage intelligibility** — proportion of utterances understood by a familiar versus unfamiliar listener, sampled in structured and spontaneous contexts.\n- **Phonetic & phonological inventory** — which target phonemes are stimulable, emerging, mastered, or in error, plus active phonological processes.\n- **Connected-speech analysis** — clarity under load (running speech), where coarticulation and rate effects surface.\n- **Generalisation probes** — whether a target sound holds across word positions, untrained words, and untrained settings (home, classroom).\n- **Functional carryover** — caregiver- and teacher-reported intelligibility in daily communication.\n\nEach 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.\n\n## Tracking within the plan\nBaseline 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.\n\n## The Pinnacle way\nDevelopmental 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.
