Outline of Final Research Achievements

In this study, we focused on a way to mask meaningful speech with some other sound achieving speech privacy/security, the masking sound system was considered for setting speech privacy/security levels using a meaningless steady masking. From the result of psychological experiments, effectiveness of the masking sound system for speech privacy/security ptotection was confirmed.
