Sonde Health Raises $19.25 Million Series B to Build the Next Generation of Voice-Based Health Monitoring

AI vocal biomarker company will use funding to accelerate its commercial growth, expand its platform into new health conditions, and enter new geographies

BOSTON – Dec. 8, 2022 – Sonde Health, a health technology company committed to bringing accessible health monitoring to everyone, has raised a $19.25 million Series B investment round led by Partners Investment, with participation from NEOM Company, KT Corporation, and existing investors, including co-founder PureTech Health and M Ventures. The company has raised $35.25 million in total and will use the funding to drive its global commercial growth, deepen its respiratory and mental health monitoring technologies, and build capabilities for additional health conditions.

“Digital biomarkers are becoming a mainstay in healthcare. Today’s healthcare companies are realizing how vocal biomarkers can engage people earlier in their health. The data and insights found in voice can power health monitoring and patient stratification so issues can become apparent well before a costly medical event occurs,” said David Liu, CEO of Sonde Health. “With voice and any listening device, accessible and effective health monitoring can be made available to the majority of the world.”

Sonde has the largest and most diverse health-labeled voice dataset with over 1.2 million voice samples from over 85,000 subjects on 4 continents. Sonde is the only vocal biomarker company to offer AI/machine learning-based monitoring products for multiple health conditions and to have developed the ability to embed its technology into device chipsets for passive and safe health monitoring through voice.

Today, Sonde provides its enterprise vocal biomarker technology to companies across several health verticals, including telehealth, pharmaceutical, remote patient monitoring, and consumer/medical devices. Sonde licenses its platform to customers globally in two ways:

  • Health Checks

    • Respiratory Fitness: Sonde’s platform can detect and monitor respiratory health conditions, like asthma, from 6 seconds of voice. Patients are engaging with Sonde’s respiratory fitness health checks 2+ times per week.
    • Mental Fitness: Sonde’s platform can detect and monitor evidence of depression and anxiety from 30 seconds of voice. Patients are engaging with Sonde’s mental fitness health checks 3+ times per week.
  • Vocal Biomarker Development

    • MCI, COPD, General Health: Sonde is developing novel vocal biomarkers using its proprietary “research-build-validation” methodology with clinical partners.

Partners Investment Vice President Joonsoo Kim will join Sonde’s board of directors. “Sonde is at the forefront of a vocal biomarker revolution that has the potential to change how we detect, manage, and understand our health. They have the deepest, high-quality dataset combined with leading edge-processing technology, which gives them a significant competitive advantage,” he said. “We believe Sonde’s team and platform are primed to disrupt and add tremendous value to health monitoring around the world, and we’re thrilled to support the company’s mission to harness the power of voice for better health.”

Sonde’s fundraise follows a stream of new and expanded commercial partnerships to accelerate development and adoption of vocal biomarkers worldwide. KT Corporation, one of the world’s leading telecom companies, announced recently that it will be working commercially with Sonde to advance its voice-based businesses, including its call centers and AI voice assistants for health monitoring. It will also deploy Sonde’s technology for applications in digital therapeutics and telemedicine in Asia.

GN Group will integrate Sonde’s Mental Fitness vocal biomarker into its hearing products. The company is already working with Sonde to develop an MCI vocal biomarker. Qualcomm, which has already integrated Sonde’s vocal biomarkers into its mobile device chipsets, has extended the relationship to include its wearable chipsets. Koye Pharmaceuticals, which had already engaged Sonde to develop a COPD vocal biomarker, has expanded the partnership to develop a novel mental health vocal biomarker for deployment in India.
