Company profile
researched Aug 2026LANGaware (operating as LANGaware Health, Inc.) develops an AI-based screening platform that analyzes speech and voice biomarkers to support the early detection of cognitive and mental health conditions, currently mild cognitive impairment (MCI), Alzheimer's disease and depression. The product is positioned as an objective decision-support system rather than a diagnostic tool; the company states that its outputs support general well-being awareness and are not a substitute for medical diagnosis or clinical decisions.
The workflow has three steps: a short elicitation task in which the participant describes an image or explains how they perform a daily activity; upload of the audio sample to the LANGaware platform, where language, speech and voice patterns are analyzed against proprietary digital biomarkers; and generation of a report containing seven data points intended to help primary care physicians and specialists make informed decisions about a patient's cognitive and mental health status. The company reports that the speaking task takes about one minute and results are returned within roughly two further minutes, for a total process of just over three minutes.
Traction
Published clinician testimonials reference use of the platform, including at-home access to LANGaware's cognitive and mental health screening tool for patients and providers, and endorsement from the chief medical officer of American TelePhysicians. The blog was active through October 2024.

Market position
Positioning emphasizes speed (a screening process completed in just over three minutes), reported accuracy validated against expert-provided ground truth labels, and accessibility — testing described as unbiased, education-independent and deployable in any setting, whether self-administered, in person or remote, in contrast to instruments such as PHQ-9 scoring, which the company's blog critiques.
Technology
The platform is built on speech analysis and proprietary voice and speech digital biomarkers, applying AI to language, speech and voice patterns extracted from a short recorded audio sample. Model training uses ground-truth labels provided by medical experts. The company reports 90% sensitivity and 85% specificity for dementia and 83% sensitivity and 80% specificity for depression, and describes the test as education-independent and administrable by self-service, in person or remotely.
Go-to-market
The website drives demand through demo requests and a self-service "Take The Test" entry point, with segment-specific pages for providers, payors, life sciences and corporate wellness. A blog ("Mind Matters") and newsletter are used for content marketing, and testimonials from clinicians, including the chief medical officer of American TelePhysicians and a practicing physician, are featured as references.
Four customer segments are addressed: healthcare providers (reduced time-to-diagnosis and more timely specialist referral with fewer resources), payors (early-priority referral of high-risk patients, cost savings and support for risk adjustment measures), life sciences companies (clinical trial participant recruitment and evaluation of participant response trends), and corporate wellness programs (employee health initiatives, reduced absenteeism and improved engagement).
