使用虚拟助手原型对抗语音垃圾邮件
Fighting Voice Spam with a Virtual Assistant Prototype
摘要：
大规模的robocalls每天影响数百万人。不幸的是，目前大多数针对机器人呼叫的防御措施都依赖于电话阻止列表，并且对来电显示欺骗无效。为了能够检测欺骗的robocalls，我们提出了一个{ \em虚拟助理}应用程序，可以集成在智能手机上，以自动审查来电。与人类助理类似，虚拟助理可以接听来电并对其进行筛选，而无需用户中断，以确定该呼叫是否不需要。通过用户研究，我们表明，我们的虚拟助理能够保留典型电话的用户体验。与此同时，我们证明了我们的系统可以检测到大量的robocalls，而不会对合法的呼叫者产生负面影响。
英文摘要：
Mass robocalls affect millions of people on a daily basis. Unfortunately, most current defenses against robocalls rely on phone blocklists and are ineffective against caller ID spoofing. To enable the detection of spoofed robocalls, we propose a {\em virtual assistant} application that could be integrated on smartphones to automatically vet incoming calls. Similar to a human assistant, the virtual assistant can pick up an incoming call and screen it without user interruption to determine if the call is unwanted. Via a user study, we show that our virtual assistant is able to preserve the user experience of a typical phone call. At the same time, we show that our system can detect mass robocalls without negatively impacting legitimate callers.
