歩行者・自転車用AARシステムにおける骨伝導ヘッドホンと風雑音抑制処理したイヤホンマイクとの比較（風雑音環境におけるアノテーション音声の了解度の検討）

Since a visual navigation system using smart-phones show information on small screens, users attention is likely to be distracted. Therefore, we are considering a portable navigation system by using Audio Augmented Reality. However, if such equipment is used outdoors, very loud wind noise is recorded with the environmental sound. Thus, to reduce this wind noise, we use wind screen and applied signal processing for wind noise reduction. In this paper, we compared noise control earphone and bone conduction headphone. It was shown that Iterative Wiener filtering improves the speech intelligibility score dramatically.
