The goal is to assess the accuracy of an application that analyzes voice characteristics to diagnose patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD). The main question is whether the application's diagnosis is the same as the clinician's for MCI and AD patients.

The study aims to assess the sensitivity and specificity of an application that uses vocal biomarkers to diagnose patients with mild cognitive impairment (MCI) and Alzheimer's disease. The application will use clinically validated survey instruments and voice recordings to determine the disease status of patients with MCI and Alzheimer's disease. The diagnosis developed by the application is the primary outcome variable. To determine the sensitivity and specificity, the application diagnosis will be compared against the physician's clinical diagnosis.
