Scientific work
in speech biomarkers

For neurodegenerative disease. Our scientific work is presented at the leading international forums in digital biomarkers and neurology, and developed in collaboration with academic and clinical research partners.

Architectural stability under real-world acoustic variability

A systematic evaluation of how on-device noise-cancellation changes — common over the lifetime of a longitudinal smartphone-based trial — affect the stability of speech biomarker outputs.

Robustness of deep-learning speech biomarkers to OS noise-cancellation variability in longitudinal Parkinson's Disease monitoring

9th Annual Digital Biomarkers in Clinical Trials Summit · Basel · Hosted in partnership with Roche.

Cephalgo SAS

Comparative evaluation of four classifier architectures under simulated post-OS-update conditions, using the Italian Parkinson's Voice and Speech Dataset. Across six scenarios of mid-study noise-cancellation algorithm change, our dual-pipeline classifier maintained sensitivity within an 11.3 percentage-point spread; three baseline architectures showed spreads of 42 – 46 percentage points. Reporting follows TRIPOD+AI.
