By analyzing just a few seconds of speech, Sonde’s platform can identify vocal characteristics linked to a wide range of physical and psychological conditions.
The company’s mission is to make health monitoring accessible, non-invasive, and continuous—without the need for wearables or lab tests. Sonde’s platform is designed to be embedded in smartphones, apps, and telehealth services, providing real-time, passive health insights for individuals and healthcare providers alike.
Sonde Health operates at the intersection of speech science, machine learning, and clinical research, offering scalable voice technology that empowers proactive care, early detection, and population-level health screening.
Features
Voice Biomarker Technology: Sonde uses proprietary AI models to analyze vocal features such as tone, pitch, rhythm, and articulation, extracting patterns associated with health conditions.
Mental Fitness: The platform can assess cognitive load, energy levels, mood, and overall mental well-being using a 30-second voice sample.
Respiratory Fitness: Sonde evaluates respiratory health by identifying signs of shortness of breath, fatigue, or compromised lung function in a 6-second voice clip.
Device-Agnostic Deployment: The technology works on virtually any device with a microphone, including smartphones, tablets, and embedded systems, allowing for widespread accessibility.
Real-Time Health Insights: Sonde’s platform delivers immediate feedback, enabling users and care providers to track changes in wellness without waiting for lab results or clinic visits.
APIs for Easy Integration: Sonde offers a suite of APIs that can be embedded into mobile apps, telehealth platforms, and connected devices for seamless integration.

Global Language Support: Sonde Health’s voice models support multiple languages and dialects, making the platform adaptable for international deployment and diverse populations.
How It Works
Sonde Health’s platform starts with a simple voice recording. A user speaks a short phrase or sentence into a microphone-enabled device, typically a smartphone or tablet. This can be done through a standalone app or any third-party platform that has integrated Sonde’s API.
The captured audio is then analyzed in real time using Sonde’s AI-based voice processing engine. This engine evaluates hundreds of vocal features and compares them to known patterns associated with mental stress, fatigue, respiratory impairment, and other health issues.
Based on this analysis, the platform delivers a wellness score or flag that can indicate potential health concerns. These results can be tracked over time, giving users and healthcare providers a dynamic view of their physical or mental state.
Because the process is fast, contactless, and passive, it’s ideal for frequent, even daily, check-ins—supporting preventive care and early intervention.
Use Cases
Sonde Health’s technology has a wide range of applications across healthcare, wellness, and digital health.
In remote patient monitoring, the platform enables clinicians to continuously assess respiratory or mental health without requiring patients to visit a clinic or wear a device.
In mental health apps, Sonde provides voice-based insights into mood, energy, and cognitive load, helping users track their mental fitness and stress levels.
In population health management, Sonde can screen large groups for early signs of health deterioration, supporting preventative care strategies in workplaces, senior care, and public health programs.
In telehealth platforms, Sonde’s voice analysis can be embedded to give providers additional insights during virtual consultations.
Wellness product companies and consumer health apps can use Sonde to offer users real-time wellness tracking features powered by voice, enhancing engagement and personalization.
Pricing
Sonde Health does not publish pricing on its official website. The platform is offered primarily as a B2B solution with custom pricing models based on deployment scale, integration requirements, and number of users.
Organizations interested in using Sonde Health’s voice technology should contact the company directly for a tailored proposal. Pricing may vary depending on the type of integration (e.g., app vs. device), the features selected (mental vs. respiratory health), and expected voice data volume.
Sonde offers partnership models for healthcare providers, telehealth platforms, app developers, and device manufacturers.
Strengths
One of Sonde Health’s key strengths is its ability to deliver health insights using only the human voice. This makes it an extremely accessible and non-invasive tool for health monitoring, with no need for wearables, sensors, or diagnostics.
The platform’s real-time analysis and API-driven integration allow businesses to add scalable health tracking to existing digital products quickly and securely.
Its support for multiple languages and dialects increases inclusivity and global reach, making it suitable for international health programs and diverse user bases.
Sonde’s strong focus on privacy and compliance ensures the technology meets regulatory standards in healthcare data protection.
The company’s voice models are backed by rigorous clinical research and are built to detect subtle changes in health status—giving it clinical value in addition to wellness applications.
Drawbacks
While Sonde Health offers powerful voice biomarker capabilities, its focus is currently limited to mental fitness and respiratory health. It does not yet cover broader diagnostic categories like cardiovascular or metabolic health.
Since the platform operates primarily in a B2B model, individual consumers cannot directly access Sonde’s services unless a third-party app or provider has implemented the technology.
Accuracy can be influenced by environmental noise, microphone quality, and the user’s speech clarity. Ensuring standardized voice capture conditions may be a challenge in real-world usage.
For organizations without in-house development teams, integrating Sonde’s APIs into existing systems may require additional technical support or third-party assistance.
The lack of publicly available pricing may also be a consideration for startups or smaller organizations evaluating digital health tools on a tight budget.
Comparison with Other Tools
Sonde Health operates in the growing space of voice biomarker technology, competing with platforms like Aural Analytics and Winterlight Labs.
Aural Analytics focuses more on neurological and speech disorder detection using linguistics and acoustic features in clinical contexts, particularly neurodegenerative diseases like ALS or Alzheimer’s.
Winterlight Labs uses voice to detect cognitive decline and mental health indicators through narrative and linguistic analysis.
Sonde Health stands out by offering real-time analysis for both mental and respiratory health using short speech samples, optimized for frequent monitoring and consumer wellness applications. Its approach is more lightweight, scalable, and designed for integration into everyday digital health tools.
While competitors lean more toward clinical research and diagnostics, Sonde is designed for proactive wellness tracking and broad-scale public health applications.
