Outline of Final Research Achievements

Subjective speech quality assessment has been used widely for the development of public-address (PA) systems, speech masking systems, hearing aid, mobile-phone, etc.
However, as this assessment is difficult in many cases, we propose an objective speech intelligibility evaluation system that includes a machine learning technique. Through outdoor-field recorded signal experiments, the effectiveness of these approaches could be verified.

Academic Significance and Societal Importance of the Research Achievements

駅や空港,学校など音声を放送する拡声システムは様々なところに実装されているが,必ずしも聴き取りやすいとは言い難い。本研究ではより聴き取りやすい拡声システムの設計に利用可能な音声の了解度(聴き取りやすさ or 聴き取りにくさ)の計測器を機械学習技術を利用して開発する。これにより身近な音声システムが聴き取りやすく最適化されることで国民生活の向上を目指す。
