Visualize Your Brain health
Through Your Voice.

An AI-powered voice analysis technology that extracts acoustic features from approximately 40 seconds of speech to visualize trends in your brain health status based on subtle changes in your voice.

Our voice analysis technology extracts acoustic features from approximately 40 seconds of speech and analyzes them with AI to visualize trends in brain health status. It can be used on everyday devices such as smartphones and PCs, and can also be integrated into services via API.
The technology can be used in a wide range of services, including insurance, municipal, and healthcare services, to help identify changes in condition and support health management.

Value for Users

Easily check trends in your brain health status through everyday conversation.
Simply speak freely for approximately 40 seconds and receive a result in two levels—“Good” or “Needs Attention.” This low-burden experience provides an opportunity to regularly check your brain health status without requiring special tests or equipment.

How the Analysis Works

How can brain health status be analyzed from the voice?
Speech contains a variety of characteristics, including speaking speed, pauses, intonation, and vocal stability.

Conversation involves a range of functions, such as thinking of words, recalling information, maintaining attention, and controlling the voice. When a person's condition changes, subtle changes may appear in speaking speed, pauses, intonation, and vocal stability—changes that may be difficult for the person or those around them to notice.
“Voice-Based Health Check” uses AI to analyze a variety of acoustic features contained in speech. By combining these features with information such as age, sex, and years of education, the technology visualizes trends in each individual's brain health status.

In addition to voice-only analysis, adding supplementary information such as age and sex can enable more accurate analysis. The technology can be flexibly adapted to a variety of services and use cases.
