Early Detection of Alzheimer's Disease and Affective Disorders by Automated Voice and Speech Analysis (PLATA)
Sponsor: Centre Hospitalier Universitaire de Nice
PLATA is testing whether an algorithm can detect early signs of Alzheimer's disease by analyzing how people speak during a phone-based cognitive task. Researchers will compare speech patterns against established biological markers like CSF proteins and PET scans. This is a diagnostic research study, not a clinical drug trial — the goal is to see if voice analysis could one day replace invasive testing like lumbar punctures. Details on phase are limited.
