Sonde Health: Voice as a vital sign

Sonde Health is a vocal biomarker platform that analyzes short voice samples or everyday speech to track mental, cognitive and respiratory health. Health companies, employers and device makers integrate it through an API and SDK, and get scores that flag changes in a person's health without extra steps from the user.

Key Features

• Mental Fitness score: Measures acoustic and prosodic vocal features from about 30 seconds of voice to give insight into depression and anxiety, with the clinically validated M3 Checklist assessment available alongside.
• Respiratory Fitness score: Estimates the likelihood of symptoms such as coughing, shortness of breath and chest tightness from 6 seconds of voice on a smartphone, covering asthma, COPD and COVID-19.
• Cognitive Fitness score: Produces a single score that reflects current cognitive effort, grouped into demanding, balanced and efficient ranges.
• Stress biomarker: Turns shifts in tone, strain and speech flow into a Stress Score that tracks the body's stress response over time.
• Passive or cued capture: Voice samples can be analyzed during everyday speech or through short, prompted sessions.
• API/SDK platform: Runs in the cloud, on the edge or embedded, across smartphones, wearables and health apps, with test and live keys for partners.
• Enterprise dashboard: Aggregates population health trends with adoption tracking, trend analysis and risk stratification by team or site.
• User verification: Checks that analyzed samples come from the enrolled, consenting user.
• Privacy and compliance: Follows GDPR and HIPAA, is SOC Type 1 and Type 2 certified, and offers on-device processing of voice data.

Use Cases

• Workforce wellbeing: Industrial employers in construction, energy, logistics and manufacturing spot fatigue, burnout and cognitive strain before they lead to accidents or turnover.
• Remote respiratory monitoring: Health and wellness organizations help people with chronic respiratory illness track symptoms and reduce exacerbations.
• Patient stratification: Companies find the right patient at the right time for outreach, medical workflows or interventions.
• Consumer health apps and devices: App and wearable makers add mental, cognitive and stress tracking to products people already use, including smart glasses.
