AD/PD™ 2026 · Copenhagen · 17–21 March 2026 · Two ePosters
Every speech reading traced to features a clinician can check
Cephalgo’s two AD/PD™ 2026 ePosters, Copenhagen, March: speech recordings distinguished people with Alzheimer’s dementia or MCI, and people with Parkinson’s, from healthy controls in existing public datasets. Each reading traces to named features.

- Data
- Recordings from two independent public datasets, analysed after the fact
Speech alone, with every reading explained
Both posters test one method on recordings that already existed: two branches read the same audio, and each reading can be traced back to named speech features.
Alzheimer’s or MCI versus healthy adults
Speech recordings distinguished people with Alzheimer’s dementia or MCI from healthy older adults of a similar age, in an independent public cohort.
Parkinson’s versus healthy controls
In the second ePoster, speech recordings distinguished people with Parkinson’s disease from healthy controls, in a second independent public dataset.
Each reading can be traced
A feature branch uses named acoustic, timing and, for Alzheimer’s, language measures, so each reading goes back to features a clinician can inspect.
Two branches, combined by agreement
A deep‑learning branch on the raw audio picks up subtle patterns the named measures do not fully capture. The two are combined through agreement‑based decision logic, which supports stable classification. Repeat recordings of the same people were used to test how well readings hold up from one test to the next.
Start with audio you already hold
The method works on recordings that already exist, so a sponsor can test it before planning any new study.
Audio from a trial you already ran
A re‑analysis pilot reads recordings you already hold, on your trial’s own scale, with the named features behind each reading. Re‑analysis pilot ›
