Smartmedical Launches Web Empath API, Identifying Emotion from Speech in Real-time.

TOKYO, March 23, 2016 /PRNewswire/ — Smartmedical Corp. announces the launch of its Web Empath API for developers. By analyzing multiple vocal properties such as intonation, pitch, speed, and volume, Empath can identify emotions in real-time, regardless of language. Our website ( offers registration for a Web Empath API key and provides a free month-long API trial.



Smartmedical Corp., is the leading authority in vocal emotion recognition.

“Just by adding sample code to a website, the API enables developers to incorporate our vocal emotion recognition technology into various applications,” says Takaaki Shimoji, a Smartmedical Corp. board director. “The API will help developers innovate by creating their own customized applications. There is a lot of potential for inventive use.”

Empath was first developed to assist with the delivery of mental healthcare services. In 2013, it was used in NTT DoCoMo’s Tohoku reconstruction project to evaluate care workers’ mental health conditions. “Some care workers assisting Tohoku earthquake victims suffered from negative mood, so we used Empath s an instrument to evaluate their mental states. If their negative moods persisted, we encouraged them to pursue counselling with doctors. This project was highly praised by Japanese media.”  

In addition to mental healthcare, Empath is utilized in various fields: robotics (with Yukai Engineering), lighting systems (with PHILIPS), virtual reality (with Intelligence, Ltd.), contact center service (with TMJ), and employee assistance programs (with NTT DoCoMo). “In the past ten years, the number of emotion recognition start-ups has increased, but Smartmedical is unique for developing multiple real use cases for our signature technology. The API will expand our fields with imaginative developers all around the world,” added Mr. Shimoji.

With a program that sends WAVE files to the API, there is potential for integration with multiple platforms including Windows, iOS, and Android OS. In addition, the API is easily adaptable for use as a M2M and IoT sensor.
