Development and Construct of Speech Privacy Protection System using High Directivity Sound Source

这项研究的重点是在无意义的稳定噪声中屏蔽语音，以实现在开放空间中的语音隐私，例如在小型诊所候诊室附近的口头咨询，在税务机关窗口的纳税咨询。利用高指向性声源构建了一种语音隐私保护系统。通过实验验证了该系统的适用性，并得到了合理的结果。

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.
