On August 29, 2025, Tokio Marine dR Co., Ltd. (hereinafter referred to as TdR) and PST Inc. (hereinafter referred to as PST) announced the launch of their business collaboration.

Through this partnership, both companies will combine their respective strengths to further enhance service quality, with the aim of promoting corporate health management and reducing employee turnover rates in Japan.

PST built a strong track record as a pioneer in the research and development of innovative “vocal biomarker” technology and their application to new businss services. We expect that this collaboration will lead to further growth and development through the synergistic effects of TdR’s extensive consulting experience and expertise and PST’s cutting-edge vocal biomarker technology.

In recent years, declining productivity and rising turnover rates due to employee mental health issues have become critical challenges for corporate management. There is a growing demand for mechanisms that can non-invasively and easily monitor employees’ physical and emotional well-being. This would enable timely and appropriate manager-led employee well-being support based on those insights.

PST has achieved remarkable success using vocal biomarker technology, particularly in fields such as call centers and logistics. For instance, in call centers, PST has effectively detected changes in the operator’s condition by analyzing the vocal patterns of employees who later left their positions. In the field of logistics, PST has demonstrated a strong correlation between drivers’ voice data and accident risk by integrating voice analysis with digital tachograph driving records (such as sudden acceleration and braking), attendance data, and accident history. This collaboration aims to expand these efforts including advancing technology and creating practical solutions: in call centers, enabling real-time detection of changes in the operator’s condition and the rapid implementation of appropriate line care; and in logistics, identifying early indicators of accident risk through voice signals to enhance both driver and public safety.

TdR and PST will leverage the expertise and insights gained through this collaboration to develop new consulting services and deliver higher-quality offerings, further advancing initiatives to promote corporate health management in Japan.
