| Research Abstract |
This study focused on masking speech with meaningless steady noise for achieving speech privacy in open spaces such as for oral consultations near waiting rooms of small-scale clinics, tax-payment consultations at a taxation office window. A speech privacy protection system was constructed using high directivity sound source. An applicability of the system was confirmed experimentally, and reasonable results were obtained.
