Dr. Masakazu Higuchi, Assistant Professor of Voice Analysis and Measurement of Pathophysiology, Graduate School of Engineering, the University of Tokyo, has published a new paper on MIMOSYS® technology of PST Inc.

In this paper, we have scientifically clarified that the minimum number of utterances in speech data required for valid analysis on MIMOSYS can be as few as three including positive phrases.
Until now, six utterances had been required to maintain the accuracy of MIMOSYS® analysis. However, MIMOSYS® can now be used more easily than ever before because of this paper published.
