System development that focuses on speech intelligibility

Purpose of Research

Measurement and control of speech quality using machine learning technology.

Summary of Research

The quality of the speech system is determined by a psychological index. For this reason, high-cost subjective evaluation is required. We propose to support development of speech system by reproducing human psychological experiments with machine learning technology.
