| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | When cyclists and pedestrians use an audio augmented reality system outdoors, very loud wind noise poses a problem. In this paper, spectral subtraction and iterative Wiener filtering methods are used in order to reduce wind noise. Speech intelligibility evaluation and sign signal (car horn and ambulance siren) recognition evaluation is carried out on processed speech. Results show that iterative Wiener filtering method is quite effective and improves speech intelligibility drastically. However, sign signal recognition ratio is degraded because the Wiener filter attenuates not only wind noise but also sign signal excessively. | |
